# Certctl Architecture
# Architecture Guide
## Overview
Certctl is a certificate management platform with a **decoupled control-plane and agent architecture**. The control plane orchestrates certificate issuance and renewal, while stateless agents deployed across your infrastructure handle certificate generation, deployment, and renewal without exposing private keys to the control plane.
Certctl is a certificate management platform with a **decoupled control-plane and agent architecture**. The control plane orchestrates certificate issuance and renewal, while agents deployed across your infrastructure handle key generation, certificate deployment, and local validation — private keys never leave the infrastructure they were generated on.
New to certificates? Read the [Concepts Guide](concepts.md) first.
### Design Principles
1. **Zero Private Key Exposure** — Private keys generated and managed only on agents
2. **Decoupled Operations** — Agents operate autonomously; control plane is optional for agent function
1. **Zero Private Key Exposure** — Private keys are generated and managed only on agents, never sent to the control plane
2. **Decoupled Operations** — Agents operate autonomously; the control plane coordinates but doesn't block agent function
3. **Audit-First** — Complete traceability of all issuance, deployment, and rotation events
4. **Connector Architecture** — Pluggable issuers, targets, and notifiers for extensibility
5. **Self-Hosted** — No cloud lock-in; run on Kubernetes, Docker, or bare metal

5. **Self-Hosted** — No cloud lock-in; run with Docker Compose, Kubernetes, or bare metal
## System Components
### Control Plane
### Control Plane (Server)
The control plane is a REST API server backed by PostgreSQL. It:
The control plane is a Go HTTP server backed by PostgreSQL. It manages state (certificates, agents, targets, issuers, policies), orchestrates issuance by coordinating with CAs through issuer connectors, tracks jobs for certificate issuance/renewal/deployment workflows, maintains an immutable audit trail, and dispatches work via a background scheduler.
- **Manages state**: Certificates, agents, targets, issuers, policies
- **Orchestrates issuance**: Coordinates with ACME/PKI issuers
- **Tracks jobs**: Certificate issuance, renewal, and deployment workflows
- **Audits all actions**: Immutable audit trail for compliance
- **Dispatches work**: Schedules renewal checks and deployment jobs
The server exposes a REST API under `/api/v1/` and optionally serves the web dashboard as static files from the `web/` directory.
**Deployment Options**: Single binary, Docker container, Kubernetes deployment
**Key internals**: The server uses Go 1.22's `net/http` stdlib routing (no external router framework), structured logging via `slog`, and a handler → service → repository layered architecture. Handlers define their own service interfaces for clean dependency inversion.
### Agents
Lightweight agents deployed on or near your infrastructure. They:
Lightweight Go processes that run on or near your infrastructure. An agent generates private keys locally, creates CSRs, receives signed certificates from the control plane, deploys them to target systems, and reports status back. Agents communicate with the control plane via HTTP and authenticate with API keys.
- **Generate certificates**: Create private keys and certificate requests
- **Deploy certificates**: Push certs to NGINX, F5, IIS, etc.
- **Manage credentials**: Store and rotate API keys with control plane
- **Report status**: Health checks and job completion status
- **Operate independently**: Continue functioning even if control plane is unreachable
The agent runs two background loops: a heartbeat (every 60 seconds) to signal it's alive, and a work poll (every 30 seconds) to check for pending jobs.
**Deployment Options**: Container, systemd service, Kubernetes DaemonSet, Lambda
### Web Dashboard
A single-page React application served as a static HTML file (`web/index.html`). It communicates with the REST API and provides a visual interface for certificate inventory, agent status, job monitoring, audit trail, policy management, and notifications.
The dashboard includes a **demo mode** that activates when the API is unreachable — it renders realistic mock data for screenshots and offline presentations.
### PostgreSQL Database
Persistent state store:
All state is stored in PostgreSQL 16. The schema uses TEXT primary keys (not UUIDs) with human-readable prefixed IDs like `mc-api-prod`, `t-platform`, `o-alice`.
Database tables:

---
Migrations are idempotent (`IF NOT EXISTS` on all CREATE statements, `ON CONFLICT (id) DO NOTHING` on all seed data) so they're safe to run multiple times — important for Docker Compose where both initdb and the server may run the same SQL.
## Data Flow: Certificate Lifecycle

```
### 3. **Deploy Certificate to Target**
### 3. Deploy Certificate to Target
```
Agent Target System
├─ Fetch target credentials from config
├─ Load certificate:
│ - /etc/certctl/api.example.com/cert.pem
│ - /etc/certctl/api.example.com/key.pem
├─ NGINX (SSH):
│ ├─ scp cert.pem → /etc/nginx/ssl/
│ ├─ scp key.pem → /etc/nginx/ssl/ (restricted perms)
│ ├─ ssh nginx -s reload
│ └─ Verify: curl https://api.example.com/health
├─ F5 (HTTPS API):
│ ├─ Authenticate with credentials
│ ├─ POST /mgmt/tm/ltm/cert {"name": "api.example.com", "cert": "..."}
│ ├─ PUT /mgmt/tm/ltm/virtual (update virtual server)
│ └─ Verify: F5 configuration updated
├─ IIS (WinRM):
│ ├─ Import cert to store: Import-PfxCertificate
│ ├─ Bind to site: Set-WebBinding
│ └─ Verify: Get-WebBinding
└─ Report deployment status:
POST /api/v1/deployments/{id}/status
{ "status": "success", "deployed_at": "..." }
```
The agent deploys certificates using target connectors. Each connector knows how to push certificates to a specific system:
### 4. **Renewal Check & Rotation**
- **NGINX**: Writes cert/chain files to disk, validates config with `nginx -t`, reloads with `nginx -s reload` or `systemctl reload nginx`
- **F5 BIG-IP**: Calls the F5 REST API to upload certificate and update virtual server bindings
- **IIS**: Uses WinRM to import the certificate into the Windows certificate store and bind it to an IIS site
```
Scheduler (Control Plane)
├─ Every hour: SELECT certificates WHERE expiry_date < NOW() + 30 days
├─ For each certificate:
│ │
│ ├─ Create renewal job
│ ├─ Notify agent(s)
│ │
│ └─ Agent flow:
│ ├─ Generate new CSR
│ ├─ Request new certificate
│ ├─ Deploy new cert to targets
│ ├─ Verify deployment
│ └─ Delete old private key from agent
├─ Log completion
└─ Notify via email/webhook
```
The agent handles both the certificate (public) and the private key (local only). The control plane never sees the private key.
---
### 4. Automatic Renewal
The control plane runs a scheduler with four background loops:
| Loop | Interval | Purpose |
|------|----------|---------|
| Renewal checker | 1 hour | Finds certificates approaching expiry, creates renewal jobs |
| Job processor | 30 seconds | Processes pending jobs (issuance, renewal, deployment) |
| Agent health check | 2 minutes | Marks agents as offline if heartbeat is stale |
| Notification processor | 1 minute | Sends pending notifications via configured channels |
When the renewal checker finds a certificate within its renewal window (e.g., 30 days before expiry), it creates a renewal job. The job processor picks it up, coordinates with the issuer, and triggers deployment. All steps are logged in the audit trail and generate notifications.
## Connector Architecture
Certctl uses **connector interfaces** for extensibility. Connectors are pluggable implementations of specific capabilities.
Certctl uses connector interfaces for extensibility. Each connector type has a standard interface that implementations must satisfy.
### Issuer Connector
Handles certificate issuance from external PKI systems.
Handles certificate issuance from CAs.
```go
type IssuerConnector interface {
// GetDirectory returns the ACME directory
GetDirectory(ctx context.Context) (*ACMEDirectory, error)
// NewAccount registers a new account
NewAccount(ctx context.Context, email string) (*Account, error)
// NewOrder creates a new certificate order
NewOrder(ctx context.Context, identifiers []Identifier) (*Order, error)
// GetAuthorization retrieves challenge info
GetAuthorization(ctx context.Context, authURL string) (*Authorization, error)
// FinalizeOrder submits CSR and gets certificate
FinalizeOrder(ctx context.Context, orderURL, csr string) ([]byte, error)
type Connector interface {
ValidateConfig(ctx context.Context, config json.RawMessage) error
IssueCertificate(ctx context.Context, request IssuanceRequest) (*IssuanceResult, error)
RenewCertificate(ctx context.Context, request RenewalRequest) (*IssuanceResult, error)
RevokeCertificate(ctx context.Context, request RevocationRequest) error
GetOrderStatus(ctx context.Context, orderID string) (*OrderStatus, error)
}
```
**Built-in Issuers**:
- `acme` — ACME v2 protocol (Let's Encrypt, Sectigo, etc.)
**Example Usage**:
```yaml
issuer:
type: acme
config:
directory_url: https://acme-v02.api.letsencrypt.org/directory
email: admin@example.com
```
Built-in issuers: **Local CA** (self-signed, for development/demos) and **ACME** (Let's Encrypt, Sectigo, etc., in progress).
### Target Connector
Deploys certificates to infrastructure systems.
Deploys certificates to infrastructure. Note: the interface does NOT include private keys — agents handle keys locally.
```go
type TargetConnector interface {
// Validate tests connectivity and credentials
Validate(ctx context.Context) error
// Deploy pushes certificate to target
Deploy(ctx context.Context, cert *Certificate) error
// Remove removes/revokes certificate from target
Remove(ctx context.Context, domain string) error
// GetStatus checks deployment status
GetStatus(ctx context.Context, domain string) (string, error)
type Connector interface {
ValidateConfig(ctx context.Context, config json.RawMessage) error
DeployCertificate(ctx context.Context, request DeploymentRequest) (*DeploymentResult, error)
ValidateDeployment(ctx context.Context, request ValidationRequest) (*ValidationResult, error)
}
```
**Built-in Targets**:
- `nginx` — NGINX via SSH
- `f5` — F5 BIG-IP via REST API
- `iis` — Microsoft IIS via WinRM
**Example Usage**:
```yaml
target:
type: nginx
config:
host: web01.prod.internal
ssh_user: deploy
ssh_key: /etc/certctl/keys/deploy.pem
cert_path: /etc/nginx/ssl
```
Built-in targets: **NGINX**, **F5 BIG-IP**, **IIS**.
### Notifier Connector
Sends notifications about certificate events.
Sends alerts about certificate lifecycle events.
```go
type NotifierConnector interface {
// Send delivers a notification
Send(ctx context.Context, notif *Notification) error
// Validate checks configuration
Validate(ctx context.Context) error
type Connector interface {
ValidateConfig(ctx context.Context, config json.RawMessage) error
SendAlert(ctx context.Context, alert Alert) error
SendEvent(ctx context.Context, event Event) error
}
```
**Built-in Notifiers**:
- `email` — SMTP email
- `webhook` — HTTP webhooks
Built-in notifiers: **Email** (SMTP) and **Webhook** (HTTP POST).
**Example Usage**:
```yaml
notifier:
type: email
config:
smtp_host: smtp.example.com
smtp_port: 587
username: alerts@example.com
password: "***"
from_address: certctl@example.com
recipients:
- ops@example.com
- security@example.com
```

## Job Lifecycle & States
Jobs represent work to be done: certificate issuance, renewal, deployment, etc.
```
┌──────────┐
│ PENDING │ Job created, waiting to be processed
└────┬─────┘
┌──────────┐
│ RUNNING │ Job in progress (CSR generation, issuance, deployment)
└────┬─────┘
├─→ SUCCESS ──→ COMPLETED (job done, no errors)
├─→ FAILURE ──→ FAILED (error occurred, may retry)
└─→ CANCEL ───→ CANCELLED (user or scheduler cancelled)
Additional states:
• RETRY_WAIT — Backoff before retry
• ABANDONED — Max retries exceeded
```
### Job Steps
Complex jobs are broken into steps:
```
Issuance Job
├─ Step 1: Notify agent of CSR request
│ Status: COMPLETED
├─ Step 2: Wait for CSR from agent
│ Status: RUNNING (timeout: 5 min)
├─ Step 3: Submit to ACME issuer
│ Status: PENDING
├─ Step 4: Poll for certificate
│ Status: PENDING
└─ Step 5: Trigger deployment jobs
Status: PENDING
```
---
See the [Connector Development Guide](connectors.md) for details on building custom connectors.
## Security Model
### Private Key Management
```
Private Key Lifecycle
├─ GENERATED on Agent (never sent to control plane)
│ └─ Location: /etc/certctl/domains/{domain}/key.pem
├─ STORED on Agent
│ ├─ File permissions: 0600 (agent user only)
│ └─ Encrypted at rest (optional, per deployment)
├─ USED on Agent for:
│ ├─ Deployment to targets
│ └─ Certificate renewal
└─ DELETED on Agent
├─ Old key deleted after successful renewal
└─ Manual revocation on agent removal
```
Private keys follow a strict lifecycle:
### Authentication & Authorization
1. **Generated on the agent** — never sent to the control plane
2. **Stored on the agent** — file permissions 0600, owned by the agent process user
3. **Used by the agent** — for deployment to targets and CSR generation
4. **Rotated by the agent** — old keys deleted after successful renewal
**Agent-to-Server**:
- API Key (registered at agent creation)
- mTLS optional for high-security deployments
- All API calls include agent ID + API key
The control plane only ever handles public material: certificates, chains, and CSRs. This is a deliberate architectural decision — even if the control plane database is compromised, no private keys are exposed.
**Server-to-External Systems**:
- ACME: ACME protocol with account key
- NGINX: SSH key authentication
- F5: Username/password or token
- IIS: WinRM with encrypted credentials
### Authentication
### Audit Logging
- **API clients → Server**: API key in `Authorization: Bearer` header, or `none` for demo mode
- **Agent → Server**: API key registered at agent creation, included in all requests
- **Server → Issuers**: ACME account key, or connector-specific credentials
- **Agent → Targets**: SSH keys, API tokens, WinRM credentials (stored locally on agent)
Every action is logged:
### Audit Trail
Every action is recorded as an immutable audit event:
```json
{
"id": "audit-98765",
"timestamp": "2024-03-14T10:30:00Z",
"actor": {
"type": "agent",
"id": "agent-prod-01"
},
"action": "certificate_issued",
"resource": {
"type": "certificate",
"id": "cert-api-example-com"
},
"status": "success",
"details": {
"issuer": "acme/letsencrypt",
"expiry": "2024-06-12T10:30:00Z",
"deployed_to": ["nginx-prod-01"]
}
"id": "audit-001",
"actor": "o-alice",
"actor_type": "User",
"action": "certificate_created",
"resource_type": "certificate",
"resource_id": "mc-api-prod",
"details": {"environment": "production"},
"timestamp": "2026-03-14T10:30:00Z"
}
```
**Query examples**:
- All actions by agent: `GET /audit/logs?actor_type=agent&actor_id=agent-001`
- All deployments: `GET /audit/logs?action=certificate_deployed`
- Last 30 days: `GET /audit/logs?from=2024-02-12`
Audit events cannot be modified or deleted. They support filtering by actor, action, resource type, resource ID, and time range.
### Data Encryption at Rest
## API Design
Optional encryption for sensitive fields:
All endpoints are under `/api/v1/` and follow consistent patterns:
- Passwords in connector configs
- API keys
- ACME account keys
- **List**: `GET /api/v1/{resources}` — returns `{data: [...], total, page, per_page}`
- **Get**: `GET /api/v1/{resources}/{id}` — returns the resource
- **Create**: `POST /api/v1/{resources}` — returns the created resource with `201`
- **Update**: `PUT /api/v1/{resources}/{id}` — returns the updated resource
- **Delete**: `DELETE /api/v1/{resources}/{id}` — returns `204` (soft delete/archive)
- **Actions**: `POST /api/v1/{resources}/{id}/{action}` — returns `202` for async operations
Uses AES-256-GCM with per-row nonce.
Resources: certificates, issuers, targets, agents, jobs, policies, teams, owners, audit, notifications.
---
## Scaling Considerations
### Control Plane Scaling
**Single Server Limits**:
- ~1000 agents (verified in testing)
- ~10,000 managed certificates
- ~100,000 audit log entries per day
**Horizontal Scaling** (future):
- Multiple server instances behind load balancer
- Shared PostgreSQL backend
- Distributed job queue (Redis/RabbitMQ)
### Agent Scaling
Agents are stateless and scale horizontally:
- Each agent processes certificates independently
- Scheduler distributes renewal checks across agents
- No inter-agent communication required
### Database Scaling
For large deployments:
- Vertical scaling: More CPU/RAM for PostgreSQL
- Read replicas: For audit log queries
- Partitioning: Audit logs by date
- Connection pooling: PgBouncer
---

# Understanding Certificates: A Beginner's Guide
If you've never worked with TLS certificates before, this guide will get you up to speed. By the end, you'll understand what certificates are, why they matter, and why managing them at scale is hard enough to need a tool like certctl.
## What Is a TLS Certificate?
When you visit `https://yourbank.com`, your browser checks a digital document called a **TLS certificate** before sending any data. That certificate proves two things: (1) you're really talking to yourbank.com and not an imposter, and (2) everything sent between you and the server is encrypted.
A TLS certificate is just a file — a small chunk of structured data that contains a **public key**, the **domain name** it belongs to, who **issued** it (the Certificate Authority), and when it **expires**. It's signed by a trusted third party so that browsers and clients can verify it's legitimate.
Think of it like a notarized ID badge for a website. The badge says "I am api.example.com," the notary (Certificate Authority) vouches for it, and anyone can check the notary's signature to confirm the badge is real.
## Why Do Certificates Expire?
Every certificate has an expiration date, typically 90 days for Let's Encrypt or up to 1 year for commercial CAs. This isn't a bug — it's a security feature. Short lifetimes limit the damage if a private key is compromised, and they force organizations to prove they still control their domains.
The problem? When you have 5 certificates, tracking expiry dates is trivial. When you have 500 certificates spread across NGINX servers, F5 load balancers, and IIS boxes in three environments, it becomes a ticking time bomb. One missed renewal means a production outage — your site goes down, your API returns errors, and your customers see scary browser warnings.
**This is the core problem certctl solves**: automated tracking, renewal, and deployment of certificates across your entire infrastructure.
## The Cast of Characters
### Certificate Authority (CA)
A CA is the trusted third party that signs your certificates. When a CA signs a cert, they're saying "we've verified that whoever asked for this certificate actually controls this domain." Browsers ship with a built-in list of CAs they trust.
Common CAs include Let's Encrypt (free, automated), DigiCert, Sectigo, and your organization's internal/private CA. Each issues certificates through different protocols and APIs.
### ACME Protocol
ACME (Automatic Certificate Management Environment) is the protocol Let's Encrypt created for automated certificate issuance. Instead of filling out forms and waiting for emails, ACME lets software request, validate, and receive certificates programmatically. The server proves domain ownership by responding to challenges — placing a specific file on the web server (HTTP-01) or creating a DNS record (DNS-01).
certctl speaks ACME natively, so it can request certificates from Let's Encrypt or any ACME-compatible CA without manual intervention.
### Private Key
Every certificate has a corresponding private key. The certificate is public — anyone can see it. The private key is secret — it's what allows your server to decrypt traffic. If someone gets your private key, they can impersonate your server.
**This is why certctl's architecture is built around a critical rule: private keys never leave the server they were generated on.** The control plane orchestrates certificate issuance and tracks state, but it never sees or stores private keys. Keys are generated locally by agents running on your infrastructure.
### Subject Alternative Names (SANs)
A single certificate can cover multiple domain names. The primary domain is the Common Name (CN), and additional domains are listed as Subject Alternative Names. For example, one cert might cover `example.com`, `www.example.com`, and `api.example.com`. This reduces the number of certificates you need to manage.
### Certificate Chain
When a CA signs your certificate, the CA itself has a certificate, which was signed by a higher-level CA, all the way up to a **root CA** that browsers trust directly. This chain of trust — your cert, signed by an intermediate CA, signed by a root CA — is called the certificate chain. Servers need to present the full chain so clients can verify the entire trust path.
## How certctl Works
certctl has three main components that work together:
### The Control Plane (Server)
This is the brain. It's a REST API server backed by PostgreSQL that tracks every certificate in your organization: what domain it covers, when it expires, who owns it, which servers it's deployed to, and its full audit history. It runs a scheduler that automatically checks for expiring certificates and triggers renewal jobs.
The control plane never touches private keys. It coordinates the certificate lifecycle — "this cert needs renewal," "deploy this cert to these targets" — but the actual cryptographic operations happen elsewhere.
### Agents
Agents are lightweight processes that run on or near your infrastructure. They do the actual work: generating private keys, creating Certificate Signing Requests (CSRs), receiving signed certificates, and deploying them to servers. An agent might run on the same machine as your NGINX server, or on a management host that has SSH access to your web servers.
The flow looks like this:
1. The scheduler on the control plane decides a certificate needs renewal
2. The control plane creates a renewal job
3. An agent picks up the job, generates a new private key locally, and sends a CSR (which contains only the public key) to the control plane
4. The control plane submits the CSR to the CA and receives the signed certificate
5. The control plane sends the signed certificate (public material only) back to the agent
6. The agent deploys the certificate and private key to the target server
7. The agent reports success back to the control plane
At no point does the private key leave the agent. This is a fundamental security property.
### Deployment Targets
Targets are the systems where certificates actually get installed — NGINX web servers, F5 BIG-IP load balancers, Microsoft IIS servers. Each target type has a **connector** that knows how to deploy certificates to that specific system (e.g., writing files and reloading NGINX config, calling the F5 REST API, running PowerShell commands on IIS via WinRM).
## The Certificate Lifecycle
Every managed certificate in certctl goes through these states:
```
Pending → Active → Expiring → (auto-renewal) → Active → ...
→ Expired (if renewal fails)
→ Failed (if issuance fails)
```
- **Pending**: Certificate record created, awaiting initial issuance
- **Active**: Certificate is valid and deployed, everything is healthy
- **Expiring**: Certificate is within the renewal window (e.g., 30 days before expiry) — renewal will be triggered automatically
- **Expired**: Certificate passed its expiration date without successful renewal — this is a problem
- **Failed**: Something went wrong during issuance or renewal — needs investigation
- **RenewalInProgress**: A renewal job is currently running
- **Archived**: Certificate was decommissioned and soft-deleted
## Why Not Just Use Certbot?
Certbot is great for a single server. It runs on one machine, gets one certificate, and installs it locally. But it doesn't solve the organizational problem: who owns which certificates? When do they expire across the fleet? Which servers need updating? Did the deployment succeed everywhere? Who changed what, and when?
certctl is for organizations that need visibility, automation, and accountability across their certificate infrastructure. It's the difference between a spreadsheet and a database — both store data, but one scales.
## Key Concepts in certctl
### Teams and Owners
Every certificate belongs to a **team** and has an **owner**. This answers the question "whose problem is it when this cert expires?" In a large organization, the platform team might own infrastructure certs while the payments team owns payment gateway certs.
### Policies
Policies are guardrails. You can enforce rules like "production certificates must use specific issuers," "all certificates must have an owner," or "certificate lifetime cannot exceed 90 days." When a certificate violates a policy, certctl flags it with a policy violation so you can take action.
### Jobs
Every action in certctl — issuing a certificate, renewing one, deploying to a target — is tracked as a **job**. Jobs have states (Pending, Running, Completed, Failed, Cancelled), retry logic, and a full audit trail. If a deployment fails, you can see exactly what happened and when.
### Audit Trail
Every action is logged: who did it, what changed, when, and why. This is essential for compliance (SOC 2, PCI-DSS, ISO 27001) and for debugging. You can trace a certificate's entire history from creation through every renewal and deployment.
### Notifications
certctl can alert you when certificates are expiring, when renewals fail, when deployments succeed, or when policy violations are detected. Notifications go out via email or webhooks, with Slack support planned.
## What's Next
Now that you understand the concepts, head to the [Quick Start Guide](quickstart.md) to get certctl running locally in under 5 minutes. You'll see a pre-loaded dashboard with demo certificates, explore the API, and understand how everything fits together.
For a deeper look at the system design, see the [Architecture Guide](architecture.md).

# Certctl Connector Development Guide
# Connector Development Guide
Connectors extend certctl to integrate with external systems for certificate issuance, deployment, and notifications. This guide covers building custom connectors from scratch.
Connectors extend certctl to integrate with external systems for certificate issuance, deployment, and notifications. This guide covers the connector interfaces, built-in implementations, and how to build your own.
## Overview
Three types of connectors:
1. **IssuerConnector** — Obtains certificates from PKI systems (ACME, Vault, DigiCert)
2. **TargetConnector** — Deploys certificates to infrastructure (NGINX, F5, IIS, Kubernetes)
3. **NotifierConnector** — Sends notifications about certificate events (Email, Webhooks, Slack)
1. **Issuer Connector** — Obtains certificates from CAs (ACME, Local CA, Vault, DigiCert)
2. **Target Connector** — Deploys certificates to infrastructure (NGINX, F5, IIS)
3. **Notifier Connector** — Sends alerts about certificate events (Email, Webhooks, Slack)
All connectors:
- Are registered with a unique type identifier
- Accept configuration at initialization
- Are used by the control plane or agents
- Are tested via validation endpoints
All connectors accept JSON configuration at initialization, support config validation, and are registered in the service layer. Issuer connectors run on the control plane; target connectors run on agents.
---
## Issuer Connector
## IssuerConnector Interface
Issuer connectors obtain signed certificates from Certificate Authorities.
Issuers obtain certificates from external PKI systems.
### Interface Definition
### Interface
```go
// internal/connector/issuer/interface.go
package issuer
type IssuerConnector interface {
// Validate checks the issuer configuration and connectivity
Validate(ctx context.Context) error
type Connector interface {
// ValidateConfig checks that the issuer configuration is valid
ValidateConfig(ctx context.Context, config json.RawMessage) error
// IssueCertificate requests a certificate for the given domains
IssueCertificate(ctx context.Context, req *IssueRequest) (*CertificateResponse, error)
// IssueCertificate submits a CSR and returns a signed certificate
IssueCertificate(ctx context.Context, request IssuanceRequest) (*IssuanceResult, error)
// RevokeCertificate revokes an issued certificate
RevokeCertificate(ctx context.Context, certPEM []byte) error
// RenewCertificate renews an existing certificate

// GetStatus returns the status of an issuance request
GetStatus(ctx context.Context, requestID string) (*StatusResponse, error)
// RevokeCertificate revokes a previously issued certificate
RevokeCertificate(ctx context.Context, request RevocationRequest) error
// GetOrderStatus checks the status of an async issuance order
GetOrderStatus(ctx context.Context, orderID string) (*OrderStatus, error)
}
type IssueRequest struct {
Domains []string // Primary domain + SANs

### Example: Vault PKI Issuer
### Built-in: Local CA
The Local CA issuer generates self-signed certificates using Go's `crypto/x509` library. It creates a CA on first use (in memory), issues certificates with proper serial numbers, validity periods, SANs, and key usage extensions.
This issuer is designed for development and demos only — certificates are self-signed and not trusted by browsers.
Configuration:
```json
{
"ca_common_name": "CertCtl Local CA",
"validity_days": 90
}
```
Location: `internal/connector/issuer/local/local.go`
### Building a Custom Issuer

### Registration
## Target Connector
Register your issuer in the connector registry:
```go
// internal/connector/issuer/registry.go
package issuer
var registry = map[string]Factory{
"acme": func(cfg Config) (IssuerConnector, error) { return acme.New(&cfg) },
"vault": func(cfg Config) (IssuerConnector, error) { return vault.New(&cfg) },
// Add more issuers here
}
func GetConnector(connectorType string, config Config) (IssuerConnector, error) {
factory, ok := registry[connectorType]
if !ok {
return nil, fmt.Errorf("unknown issuer type: %s", connectorType)
}
return factory(config)
}
```
---
## TargetConnector Interface
Targets deploy certificates to infrastructure.
### Interface Definition
Target connectors deploy certificates to infrastructure systems. They run on agents, not on the control plane.
### Interface
```go
// internal/connector/target/interface.go
package target
type TargetConnector interface {
// Validate tests connectivity and credentials
Validate(ctx context.Context) error
type Connector interface {
// ValidateConfig checks target configuration
ValidateConfig(ctx context.Context, config json.RawMessage) error
// Deploy pushes the certificate to the target
Deploy(ctx context.Context, req *DeployRequest) (*DeployResponse, error)
// DeployCertificate pushes a certificate to the target system
DeployCertificate(ctx context.Context, request DeploymentRequest) (*DeploymentResult, error)
// Remove removes/revokes a certificate from the target
Remove(ctx context.Context, domain string) error
// GetStatus checks the deployment status
GetStatus(ctx context.Context, domain string) (*StatusResponse, error)
// ValidateDeployment verifies a certificate was deployed correctly
ValidateDeployment(ctx context.Context, request ValidationRequest) (*ValidationResult, error)
}
type DeployRequest struct {
Domain string // Primary domain
Certificate []byte // Signed certificate (PEM)
PrivateKey []byte // Private key (PEM) - optional
CertificateChain []byte // CA chain (PEM)
type DeploymentRequest struct {
CertPEM string // Signed certificate (PEM)
ChainPEM string // CA chain (PEM)
TargetConfig json.RawMessage // Target-specific config
Metadata map[string]string
// NOTE: No private key — agents handle keys locally
}
type DeployResponse struct {
RequestID string
Status string // "success", "pending", "error"
type DeploymentResult struct {
Success bool
TargetAddress string
DeploymentID string
Message string
DeployedAt time.Time
Metadata map[string]string
}
type StatusResponse struct {
Status string // "deployed", "pending", "failed"
DeployedAt time.Time
Error string
}
```
### Example: Custom Load Balancer Target
```go
package lb
import (
"bytes"
"context"
"encoding/json"
"fmt"
"net/http"
)
type LBConfig struct {
Host string // Load balancer hostname

}
}
// Validate tests connectivity
func (lb *LoadBalancerTarget) Validate(ctx context.Context) error {

}
return nil
}
// Deploy pushes certificate to the load balancer
func (lb *LoadBalancerTarget) Deploy(ctx context.Context, req *target.DeployRequest) (
*target.DeployResponse, error) {
body := map[string]interface{}{
"domain": req.Domain,
"certificate": string(req.Certificate),

## NotifierConnector Interface
Notifiers send alerts about certificate events.
### Interface Definition
```go
package notifier
type NotifierConnector interface {
// Validate checks configuration
Validate(ctx context.Context) error
// Send delivers a notification
Send(ctx context.Context, notification *Notification) error
}
type Notification struct {
EventType string // "certificate_issued", "renewal_failed", "deployment_success"
Subject string
Body string
Severity string // "info", "warning", "error"
type ValidationResult struct {
Valid bool
Serial string
TargetAddress string
Message string
ValidatedAt time.Time
Metadata map[string]string
}
```
### Example: Slack Notifier
### Built-in: NGINX
```go
package slack
The NGINX connector writes certificate and chain files to disk, validates the NGINX configuration, and reloads the server.
import (
"bytes"
"context"
"encoding/json"
"fmt"
"net/http"
)
type SlackConfig struct {
WebhookURL string // Slack incoming webhook URL
Channel string // Optional: override channel
Username string // Bot username
}
type SlackNotifier struct {
config *SlackConfig
client *http.Client
}
func New(cfg *SlackConfig) *SlackNotifier {
return &SlackNotifier{
config: cfg,
client: &http.Client{Timeout: 10 * time.Second},
}
}
// Validate checks webhook connectivity
func (s *SlackNotifier) Validate(ctx context.Context) error {
payload := map[string]interface{}{
"text": "Certctl test message",
}
data, _ := json.Marshal(payload)
resp, err := s.client.Post(s.config.WebhookURL, "application/json", bytes.NewReader(data))
if err != nil {
return err
}
defer resp.Body.Close()
if resp.StatusCode != http.StatusOK {
return fmt.Errorf("slack webhook returned %d", resp.StatusCode)
}
return nil
}
// Send posts a message to Slack
func (s *SlackNotifier) Send(ctx context.Context, notif *notifier.Notification) error {
color := "good"
if notif.Severity == "error" {
color = "danger"
} else if notif.Severity == "warning" {
color = "warning"
}
payload := map[string]interface{}{
"username": s.config.Username,
"attachments": []map[string]interface{}{
Configuration:
```json
{
"title": notif.Subject,
"text": notif.Body,
"color": color,
"fields": formatMetadata(notif.Metadata),
},
},
}
data, _ := json.Marshal(payload)
resp, err := s.client.Post(s.config.WebhookURL, "application/json", bytes.NewReader(data))
if err != nil {
return err
}
defer resp.Body.Close()
if resp.StatusCode != http.StatusOK {
return fmt.Errorf("slack post failed: %d", resp.StatusCode)
}
return nil
}
func formatMetadata(m map[string]string) []map[string]interface{} {
fields := []map[string]interface{}{}
for k, v := range m {
fields = append(fields, map[string]interface{}{
"title": k,
"value": v,
"short": true,
})
}
return fields
"cert_path": "/etc/nginx/certs/cert.pem",
"chain_path": "/etc/nginx/certs/chain.pem",
"reload_command": "systemctl reload nginx",
"validate_command": "nginx -t"
}
```
---
The connector writes cert and chain files with mode 0644, runs the validation command first (so a bad config doesn't take down NGINX), and only reloads if validation passes.
Location: `internal/connector/target/nginx/nginx.go`
### Built-in: F5 BIG-IP
Deploys certificates via the F5 REST API. Uploads the certificate and key, then updates virtual server SSL profiles.
Location: `internal/connector/target/f5/f5.go`
### Built-in: IIS
Deploys certificates to Microsoft IIS via WinRM. Imports the certificate into the Windows certificate store and binds it to an IIS site.
Location: `internal/connector/target/iis/iis.go`
## Notifier Connector
Notifier connectors send alerts about certificate lifecycle events (expiration warnings, renewal success/failure, deployment status, policy violations).
### Interface
The service layer defines a simple notifier interface:
```go
// internal/service/notification.go
type Notifier interface {
Send(ctx context.Context, recipient string, subject string, body string) error
Channel() string
}
```
The connector layer has a richer interface:
```go
// internal/connector/notifier/interface.go
type Connector interface {
ValidateConfig(ctx context.Context, config json.RawMessage) error
SendAlert(ctx context.Context, alert Alert) error
SendEvent(ctx context.Context, event Event) error
}
```
Built-in notifiers: **Email** (SMTP) and **Webhook** (HTTP POST).
In demo mode, notifications are marked as "sent" even without a configured notifier — this prevents error spam in the logs while still generating notification records for the dashboard to display.
## Registering a Connector
To add a new connector:
1. Create a package under the appropriate directory:
- `internal/connector/issuer/myissuer/`
- `internal/connector/target/mytarget/`
- `internal/connector/notifier/mynotifier/`
2. Implement the interface (all methods required)
3. Register it in the service layer during server initialization in `cmd/server/main.go`:
```go
// For issuers
issuerRegistry := map[string]service.IssuerConnector{
"local": localCAConnector,
"acme": acmeConnector,
"vault": vaultConnector, // your new issuer
}
// For notifiers
notifierRegistry := map[string]service.Notifier{
"Email": emailNotifier,
"Webhook": webhookNotifier,
"Slack": slackNotifier, // your new notifier
}
```
## Testing Connectors
### Unit Tests
```go
package vault
import (
"context"
"testing"
)
func TestValidate(t *testing.T) {
cfg := &VaultConfig{
Address: "http://localhost:8200",
Token: "test-token",
func TestNginxDeploy(t *testing.T) {
cfg := &nginx.Config{
CertPath: "/tmp/test-cert.pem",
ChainPath: "/tmp/test-chain.pem",
ReloadCommand: "echo reloaded",
ValidateCommand: "echo valid",
}
issuer := New(cfg)
connector := nginx.New(cfg, slog.Default())
err := issuer.Validate(context.Background())
if err == nil {
t.Fatal("expected error for invalid token")
}
}
func TestIssueCertificate(t *testing.T) {
// Mock Vault responses or use Vault test harness
cfg := &VaultConfig{/* ... */}
issuer := New(cfg)
req := &issuer.IssueRequest{
Domains: []string{"example.com"},
CSR: testCSR,

## Registering Custom Connectors
### 1. Create Connector Package
```
internal/connector/issuer/myissuer/
├── issuer.go # Implementation
└── config.go # Configuration validation
```
### 2. Implement Interface
```go
package myissuer
type MyIssuer struct {
config *Config
}
func (m *MyIssuer) Validate(ctx context.Context) error {
// Validation logic
}
func (m *MyIssuer) IssueCertificate(ctx context.Context, req *issuer.IssueRequest) (*issuer.CertificateResponse, error) {
// Issuance logic
}
```
### 3. Register in Factory
```go
// internal/connector/issuer/factory.go
import "github.com/shankar0123/certctl/internal/connector/issuer/myissuer"
var factories = map[string]ConnectorFactory{
"myissuer": func(cfg interface{}) (IssuerConnector, error) {
return myissuer.New(cfg.(*myissuer.Config))
},
}
```
### 4. Add Configuration Schema
```go
// Validate connector configuration at registration
func ValidateConfig(connectorType string, config interface{}) error {
switch connectorType {
case "myissuer":
cfg := config.(*MyConfig)
if cfg.Host == "" {
return fmt.Errorf("host is required")
}
if cfg.Token == "" {
return fmt.Errorf("token is required")
}
}
return nil
}
```
### 5. Use in Your Application
```go
// Get connector
connector, err := issuer.GetConnector("myissuer", config)
// Issue certificate
resp, err := connector.IssueCertificate(ctx, issueReq)
```
---
## Best Practices
1. **Error Handling** — Return descriptive errors with context
2. **Timeout Management** — Always use context with timeouts
3. **Validation** — Validate configuration during Validate()
4. **Retry Logic** — Handle transient failures gracefully
5. **Logging** — Log all operations for debugging
6. **Testing** — Provide unit and integration tests
7. **Documentation**Document configuration options and limitations
8. **Security** — Never log sensitive data (tokens, keys, passwords)
1. **Always validate config** — Check all required fields in `ValidateConfig` before any operation
2. **Use context for timeouts** — All connector methods accept `context.Context`; honor cancellation and deadlines
3. **Return descriptive errors** — Wrap errors with context so failures are diagnosable from logs
4. **Never log secrets** — Don't log API tokens, passwords, or private key material
5. **Support dry-run** — Where possible, support a validation/dry-run mode for deployment testing
6. **Idempotent operations** — Deploying the same certificate twice should succeed, not fail
7. **Report metadata**Return deployment duration, target address, and other useful data in results

# Advanced Demo: Certificate Lifecycle End-to-End
This demo goes beyond browsing pre-loaded data. You'll create a team, register an owner, set up an issuer, create a certificate, trigger renewal, and watch everything appear in the dashboard in real time. By the end, you'll understand the full certificate lifecycle as certctl manages it.
**Time**: 10-15 minutes
**Prerequisites**: certctl running via Docker Compose (see [Quick Start](quickstart.md))
## Setup
Make sure certctl is running:
```bash
docker compose -f deploy/docker-compose.yml up -d
# Wait for healthy status
docker compose -f deploy/docker-compose.yml ps
```
Open **http://localhost:8443** in your browser alongside your terminal. You'll watch changes appear in the dashboard as you make API calls.
Set up a base variable for convenience:
```bash
API="http://localhost:8443"
```
## Part 1: Build the Organization Structure
### Create a new team
```bash
curl -s -X POST $API/api/v1/teams \
-H "Content-Type: application/json" \
-d '{
"id": "t-demo",
"name": "Demo Team",
"description": "Team created during advanced demo walkthrough"
}' | jq .
```
### Register an owner
```bash
curl -s -X POST $API/api/v1/owners \
-H "Content-Type: application/json" \
-d '{
"id": "o-demo-user",
"name": "Demo User",
"email": "demo@example.com",
"team_id": "t-demo"
}' | jq .
```
Verify both exist:
```bash
curl -s $API/api/v1/teams/t-demo | jq .
curl -s $API/api/v1/owners/o-demo-user | jq .
```
## Part 2: Configure the Issuer
The demo ships with a Local CA issuer (`iss-local`) that can sign certificates immediately — no external CA needed. Let's verify it's available:
```bash
curl -s $API/api/v1/issuers/iss-local | jq .
```
You should see:
```json
{
"id": "iss-local",
"name": "Local Dev CA",
"type": "GenericCA",
"enabled": true
}
```
This Local CA generates real X.509 certificates using Go's `crypto/x509` library. The certificates are self-signed (not trusted by browsers in production), but structurally identical to production certificates — they have serial numbers, validity periods, SANs, key usage extensions, and a proper certificate chain.
## Part 3: Create a Managed Certificate
Now the main event. Let's create a certificate for a fictional internal API:
```bash
curl -s -X POST $API/api/v1/certificates \
-H "Content-Type: application/json" \
-d '{
"id": "mc-demo-api",
"name": "Demo API Certificate",
"common_name": "demo-api.internal.example.com",
"sans": ["demo-api.internal.example.com", "demo-api-v2.internal.example.com"],
"environment": "staging",
"owner_id": "o-demo-user",
"team_id": "t-demo",
"issuer_id": "iss-local",
"renewal_policy_id": "rp-default",
"status": "Pending",
"tags": {
"service": "demo-api",
"created_by": "advanced-demo",
"tier": "internal"
}
}' | jq .
```
**Check the dashboard now.** Click "Certificates" in the sidebar. You'll see your new "Demo API Certificate" with status "Pending" alongside the pre-loaded demo certificates. Click on it to see the full details: owner, team, environment, tags, and timeline.
### Verify via API
```bash
curl -s $API/api/v1/certificates/mc-demo-api | jq '{id, name, common_name, status, environment, owner_id, team_id}'
```
## Part 4: Trigger Certificate Renewal
In production, the scheduler automatically triggers renewal when certificates approach expiry. For this demo, we'll trigger it manually:
```bash
curl -s -X POST $API/api/v1/certificates/mc-demo-api/renew | jq .
```
Expected response:
```json
{
"status": "renewal_triggered"
}
```
This creates a renewal job. Check the jobs list:
```bash
curl -s "$API/api/v1/jobs" | jq '.data[] | select(.certificate_id == "mc-demo-api") | {id, type, status, certificate_id}'
```
**Check the dashboard.** Go to the "Jobs" view — you'll see the renewal job for your certificate.
## Part 5: Deploy the Certificate
Trigger deployment to see the deployment workflow:
```bash
curl -s -X POST $API/api/v1/certificates/mc-demo-api/deploy | jq .
```
Expected response:
```json
{
"status": "deployment_triggered"
}
```
Check for deployment jobs:
```bash
curl -s "$API/api/v1/jobs" | jq '.data[] | select(.certificate_id == "mc-demo-api")'
```
## Part 6: View the Audit Trail
Every action you've taken has been recorded. Check the audit trail:
```bash
curl -s $API/api/v1/audit | jq '.data[0:5]'
```
You'll see events for certificate creation, renewal trigger, and deployment trigger — each with actor, action, resource type, and timestamp.
**Check the dashboard.** The "Audit" view shows the full timeline of all actions across the system.
## Part 7: Check Notifications
Certctl sends notifications for certificate lifecycle events. Check what notifications were generated:
```bash
curl -s $API/api/v1/notifications | jq '.data[0:5]'
```
In demo mode, notifications are marked as "sent" even without a real email/webhook backend. In production, these would go out via SMTP or HTTP webhooks.
## Part 8: Create a Second Certificate and Compare
Let's create another certificate in production to see how the dashboard handles multiple environments:
```bash
curl -s -X POST $API/api/v1/certificates \
-H "Content-Type: application/json" \
-d '{
"id": "mc-demo-payments",
"name": "Demo Payments Gateway",
"common_name": "payments.example.com",
"sans": ["payments.example.com", "checkout.example.com"],
"environment": "production",
"owner_id": "o-demo-user",
"team_id": "t-demo",
"issuer_id": "iss-local",
"renewal_policy_id": "rp-default",
"status": "Active",
"expires_at": "2026-04-01T00:00:00Z",
"tags": {
"service": "payments",
"pci": "true",
"tier": "critical"
}
}' | jq .
```
This certificate expires in about 18 days from the demo date, so it should show up as "Expiring" in the dashboard when the scheduler runs. **Refresh the dashboard** — you'll see it in the certificate list.
Now filter the dashboard by environment or status to see how the filtering works with your new certificates mixed in with the demo data.
## Part 9: Policy Violations
Let's see what happens when a certificate doesn't meet policy requirements. Check existing policy rules:
```bash
curl -s $API/api/v1/policies | jq '.data[] | {id, name, type, enabled}'
```
The demo includes rules for required owner metadata, allowed environments, maximum certificate lifetime, and minimum renewal windows. Check existing violations:
```bash
curl -s "$API/api/v1/policies/pr-max-certificate-lifetime/violations" | jq .
```
**In the dashboard**, click "Policies" in the sidebar to see all active rules and which certificates are violating them.
## Full Automated Script
Here's a single script that runs the entire demo end-to-end. Save it as `demo.sh` and run it:
```bash

## What to Show Stakeholders
If you're using this demo to present certctl to decision-makers, here's the narrative:
1. **Start with the dashboard** — "This is your certificate inventory. Every TLS certificate across your infrastructure, in one place."
2. **Point to expiring certs** — "These certificates would have caused outages. Certctl catches them automatically."
3. **Show the cert you just created** — "I just created this via the API. It's already tracked, assigned to a team, and will be renewed automatically."
4. **Show the audit trail** — "Complete traceability. Every action, every change, every deployment — timestamped and attributed."
5. **Show policies** — "Guardrails. We enforce that every certificate has an owner, uses approved CAs, and stays within allowed environments."
6. **Show agents** — "Private keys never touch the control plane. Agents handle cryptographic operations locally on your infrastructure."
7. **Show the API** — "Everything is API-first. The dashboard is just one consumer. You can integrate with CI/CD, Terraform, or custom tooling."

---
## Walk-Through: Create Your First Certificate
### Step 1: Verify API Access
```bash
curl -X GET http://localhost:8443/health
```
Response:
```json
{"status":"healthy"}
```
### Step 2: Create a Team (Optional)
## Open the Dashboard
Teams organize ownership and auditing. For this quick start, we'll use a default team.
Open **http://localhost:8443** in your browser.
The dashboard comes pre-loaded with 14 demo certificates across multiple teams, environments, and statuses. You'll see expiring certs, expired certs, active certs, failed renewals — a realistic snapshot of what a certificate inventory looks like in a real organization.
Explore the sidebar: Certificates, Agents, Policies, Jobs, Audit Trail, Notifications. Everything you see in the dashboard is backed by the REST API.
## Explore the API
The dashboard reads from the same REST API you can call directly. All endpoints live under `/api/v1/` and return JSON.
### List all certificates
```bash
TEAM_ID="default"
curl -s http://localhost:8443/api/v1/certificates | jq .
```
### Step 3: Register an ACME Issuer
Create a certificate issuer configuration (Let's Encrypt staging for this demo):
```bash
curl -X POST http://localhost:8443/api/v1/issuers \
-H "Content-Type: application/json" \
-d '{
"team_id": "default",
"name": "lets-encrypt-staging",
"type": "acme",
"config": {
"directory_url": "https://acme-staging-v02.api.letsencrypt.org/directory",
"email": "admin@example.com"
}
}'
```
Response (save the `issuer_id`):
The response has this shape:
```json
{
"id": "issuer-abc123",
"name": "lets-encrypt-staging",
"type": "acme",
"created_at": "2024-03-14T10:30:00Z"
"data": [
{
"id": "mc-api-prod",
"name": "API Production",
"common_name": "api.example.com",
"sans": ["api.example.com", "api-v2.example.com"],
"environment": "production",
"owner_id": "o-alice",
"team_id": "t-platform",
"issuer_id": "iss-local",
"status": "Active",
"expires_at": "2026-05-28T00:00:00Z",
"tags": {"service": "api-gateway", "tier": "critical"},
"created_at": "2026-03-14T00:00:00Z",
"updated_at": "2026-03-14T00:00:00Z"
}
],
"total": 14,
"page": 1,
"per_page": 50
}
```
Store the issuer ID:
### Filter by status
```bash
ISSUER_ID="issuer-abc123"
# Get only expiring certificates
curl -s "http://localhost:8443/api/v1/certificates?status=Expiring" | jq .
# Get only production certificates
curl -s "http://localhost:8443/api/v1/certificates?environment=production" | jq .
```
### Step 4: Register an Agent
Agents handle certificate requests and deployment. Register one:
### Get a specific certificate
```bash
curl -X POST http://localhost:8443/api/v1/agents \
curl -s http://localhost:8443/api/v1/certificates/mc-api-prod | jq .
```
### List agents
```bash
curl -s http://localhost:8443/api/v1/agents | jq .
```
### View audit trail
```bash
curl -s http://localhost:8443/api/v1/audit | jq .
```
### View policy rules
```bash
curl -s http://localhost:8443/api/v1/policies | jq .
```
### View notifications
```bash
curl -s http://localhost:8443/api/v1/notifications | jq .
```
## Create Your First Certificate
Let's create a new managed certificate from scratch using the API. This will create a certificate record that certctl will track, renew, and deploy.
### Step 1: Create a certificate
```bash
curl -s -X POST http://localhost:8443/api/v1/certificates \
-H "Content-Type: application/json" \
-d '{
"team_id": "default",
"name": "quickstart-agent",
"description": "Local development agent"
}'
"name": "My First Certificate",
"common_name": "myapp.example.com",
"sans": ["myapp.example.com", "www.myapp.example.com"],
"environment": "staging",
"owner_id": "o-alice",
"team_id": "t-platform",
"issuer_id": "iss-local",
"renewal_policy_id": "rp-default",
"status": "Pending",
"tags": {"purpose": "quickstart-demo"}
}' | jq .
```
Response (save the `api_key` and `id`):
The server returns the created certificate with an auto-generated ID:
```json
{
"id": "agent-xyz789",
"name": "quickstart-agent",
"api_key": "ey...",
"registered_at": "2024-03-14T10:30:00Z",
"status": "registered"
"id": "a1b2c3d4-...",
"name": "My First Certificate",
"common_name": "myapp.example.com",
"status": "Pending",
"created_at": "2026-03-14T..."
}
```
Store the agent details:
Save the certificate ID:
```bash
AGENT_ID="agent-xyz789"
AGENT_API_KEY="ey..."
CERT_ID="<paste the id from the response>"
```
### Step 5: Create a Deployment Target
Targets are where certificates will be deployed (NGINX, F5, etc.). For this demo, we'll skip actual deployment:
### Step 2: Trigger renewal
```bash
curl -X POST http://localhost:8443/api/v1/targets \
-H "Content-Type: application/json" \
-d '{
"team_id": "default",
"agent_id": "'$AGENT_ID'",
"name": "example-nginx",
"type": "nginx",
"config": {
"host": "nginx.example.com",
"ssh_user": "deploy",
"ssh_key": "/path/to/key",
"cert_path": "/etc/nginx/ssl"
}
}'
curl -s -X POST http://localhost:8443/api/v1/certificates/$CERT_ID/renew | jq .
```
Response:
```json
{
"id": "target-def456",
"name": "example-nginx",
"agent_id": "agent-xyz789",
"type": "nginx",
"status": "pending_validation"
}
```
This creates a renewal job that will be processed by the scheduler.
Store the target ID:
```bash
TARGET_ID="target-def456"
```
### Step 6: Create a Managed Certificate
Now the main event—request a certificate to be issued and managed:
### Step 3: Check the certificate
```bash
curl -X POST http://localhost:8443/api/v1/certificates \
-H "Content-Type: application/json" \
-d '{
"team_id": "default",
"domain": "api.example.com",
"issuer_id": "'$ISSUER_ID'",
"target_ids": ["'$TARGET_ID'"],
"renewal_days_before": 30,
"auto_deploy": true
}'
curl -s http://localhost:8443/api/v1/certificates/$CERT_ID | jq .
```
Response:
```json
{
"id": "cert-ghi012",
"domain": "api.example.com",
"issuer_id": "issuer-abc123",
"status": "pending",
"created_at": "2024-03-14T10:30:00Z",
"expires_at": null,
"renewal_at": null
}
```
Store the certificate ID:
```bash
CERT_ID="cert-ghi012"
```
### Step 7: Check Certificate Status
Poll the certificate status as issuance progresses:
### Step 4: Check the audit trail
```bash
curl -X GET http://localhost:8443/api/v1/certificates/$CERT_ID \
-H "Content-Type: application/json"
curl -s http://localhost:8443/api/v1/audit | jq '.data[0:3]'
```
Response (will change over time):
```json
{
"id": "cert-ghi012",
"domain": "api.example.com",
"status": "issued",
"expires_at": "2024-06-12T10:30:00Z",
"issued_by": "issuer-abc123",
"deployed_to": [
{
"target_id": "target-def456",
"status": "success",
"deployed_at": "2024-03-14T10:30:30Z"
}
]
}
```
Refresh the dashboard at http://localhost:8443 — your new certificate appears in the inventory.
### Step 8: View Audit Trail
## Understanding the Demo Data
See all actions related to your certificate:
The demo comes pre-loaded with realistic data so you can explore certctl's features immediately:
| Resource | Count | Examples |
|----------|-------|---------|
| Teams | 5 | Platform, Security, Payments, Frontend, Data |
| Owners | 5 | Alice, Bob, Carol, Dave, Eve |
| Issuers | 3 | Local Dev CA, Let's Encrypt Staging, DigiCert |
| Agents | 5 | nginx-prod, nginx-staging, f5-prod, iis-prod, data-agent |
| Targets | 5 | NGINX (prod/staging/data), F5 LB, IIS |
| Certificates | 14 | Various statuses: Active, Expiring, Expired, Failed |
| Policies | 4 | Required owner, allowed environments, max lifetime, min renewal window |
Certificates have varied statuses so you can see what each state looks like in the dashboard: healthy certs with 45+ days remaining, certs about to expire (5-12 days), certs that already expired, and a failed renewal.
## Tear Down
```bash
curl -X GET "http://localhost:8443/api/v1/audit/logs?resource_id=$CERT_ID" \
-H "Content-Type: application/json"
docker compose -f deploy/docker-compose.yml down -v
```
Response:
```json
{
"logs": [
{
"id": "audit-001",
"timestamp": "2024-03-14T10:30:00Z",
"actor": {
"type": "api",
"id": "client-001"
},
"action": "certificate_created",
"resource": {
"type": "certificate",
"id": "cert-ghi012"
},
"status": "success"
},
{
"id": "audit-002",
"timestamp": "2024-03-14T10:30:10Z",
"actor": {
"type": "agent",
"id": "agent-xyz789"
},
"action": "certificate_issued",
"resource": {
"type": "certificate",
"id": "cert-ghi012"
},
"status": "success",
"details": {
"issuer": "lets-encrypt-staging",
"expiry": "2024-06-12"
}
},
{
"id": "audit-003",
"timestamp": "2024-03-14T10:30:25Z",
"actor": {
"type": "system",
"id": "scheduler"
},
"action": "certificate_deployed",
"resource": {
"type": "certificate",
"id": "cert-ghi012"
},
"status": "success",
"details": {
"deployed_to": "example-nginx"
}
}
]
}
```
The `-v` flag removes the PostgreSQL data volume so you get a clean slate next time.
### Step 9: Trigger Manual Renewal (Optional)
## What's Next
To manually trigger certificate renewal:
```bash
curl -X POST http://localhost:8443/api/v1/certificates/$CERT_ID/renew \
-H "Content-Type: application/json"
```
The scheduler will automatically check for renewals every hour. Certificates within 30 days of expiry are renewed automatically.

## Development Mode
For development with hot reload and database browser:
```bash
# Install tools
make install-tools
# Start dev stack (includes PgAdmin at localhost:5050)
make docker-up-dev
# View logs
make docker-logs-server
make docker-logs-agent
# Admin credentials for PgAdmin:
# Email: admin@example.com (default, see .env)
# Password: admin (default, see .env)
# Access PgAdmin: http://localhost:5050
# Add server: postgres, port 5432, user certctl, password certctl
```
---
## Testing the Flow End-to-End
Here's a complete script to test the full flow:
```bash
#!/bin/bash
set -e
API="http://localhost:8443"
TEAM="default"
echo "1. Creating ACME issuer..."
ISSUER=$(curl -s -X POST $API/api/v1/issuers \
-H "Content-Type: application/json" \
-d '{
"team_id": "'$TEAM'",
"name": "letsencrypt-staging",
"type": "acme",
"config": {
"directory_url": "https://acme-staging-v02.api.letsencrypt.org/directory",
"email": "test@example.com"
}
}' | jq -r '.id')
echo " Issuer: $ISSUER"
echo "2. Registering agent..."
AGENT=$(curl -s -X POST $API/api/v1/agents \
-H "Content-Type: application/json" \
-d '{
"team_id": "'$TEAM'",
"name": "test-agent"
}' | jq -r '.id')
echo " Agent: $AGENT"
echo "3. Creating certificate..."
CERT=$(curl -s -X POST $API/api/v1/certificates \
-H "Content-Type: application/json" \
-d '{
"team_id": "'$TEAM'",
"domain": "test-'$(date +%s)'.example.com",
"issuer_id": "'$ISSUER'",
"renewal_days_before": 30
}' | jq -r '.id')
echo " Certificate: $CERT"
echo "4. Checking status..."
curl -s -X GET $API/api/v1/certificates/$CERT | jq '.status'
echo "5. Viewing audit trail..."
curl -s -X GET "$API/api/v1/audit/logs?resource_id=$CERT" | jq '.logs | length'
echo "Done!"
```
Save as `test.sh`, make executable, and run:
```bash
chmod +x test.sh
./test.sh
```
---
## Common Issues
### Server Won't Start
```bash
# Check database connection
psql -h localhost -U certctl -d certctl -c "SELECT 1"
# View logs
make docker-logs-server
# Check environment
env | grep DB_
```
### Agent Can't Connect
```bash
# Verify server is running
curl http://localhost:8443/health
# Check agent logs
docker logs certctl-agent
# Verify API key is correct
echo $AGENT_API_KEY
```
### Certificate Stays "Pending"
```bash
# Check if agent is registered
curl http://localhost:8443/api/v1/agents
# Check agent logs for errors
make docker-logs-agent
# View certificate details
curl http://localhost:8443/api/v1/certificates/$CERT_ID
# Check audit trail
curl "http://localhost:8443/api/v1/audit/logs?resource_id=$CERT_ID"
```

## Next Steps
1. **Read** [docs/architecture.md](architecture.md) to understand the design
2. **Explore** the [API](../README.md#api-overview) for more operations
3. **Build** a [custom connector](connectors.md) for your infrastructure
4. **Deploy** to production using [docs/k8s-deployment.md](k8s-deployment.md) (coming soon)
