target(azurekv): SDK-driven Azure Key Vault target connector
Closes Rank 5 (Azure half) of the 2026-05-03 Infisical deep-research deliverable (cowork/infisical-deep-research-results.md Part 5). Pre-fix, certctl had no path to deploy certs to Azure-managed TLS- termination endpoints (Application Gateway / Front Door / App Service / Container Apps) — operators terminating TLS at Azure had to use manual `az keyvault certificate import` invocations or external automation. This commit lands the SDK-driven Azure Key Vault target connector that closes the gap, mirroring the AWS ACM target shape shipped in commitedf6bee. Architecture: - internal/connector/target/azurekv/azurekv.go — Connector wraps *azcertificates.Client behind the KeyVaultClient interface seam (mirrors awsacm's ACMClient + awsacmpca's ACMPCAClient). Lives in azurekv.go alongside the PFX (PKCS#12) wrapping helper that bundles the operator-supplied PEM cert + chain + key into the base64-PFX wire format azcertificates.ImportCertificate accepts. - internal/connector/target/azurekv/sdk_client.go — SDK-loading code isolated so the test path (NewWithClient) compiles without pulling azcore + azidentity transitive deps into the test binary. DefaultAzureCredential / ManagedIdentityCredential / EnvironmentCredential / WorkloadIdentityCredential selected via Config.CredentialMode (closed enum). - Pre-deploy snapshot via GetCertificate(name, "" /* latest */) so on-import-failure rollback restores the previous cert. Mirrors Bundle 5+. The Azure-specific quirk: rollback creates a NEW VERSION (Key Vault doesn't support version-restore without soft-delete recovery, which we keep off the minimum-RBAC surface). Operators reading audit dashboards see e.g. v1=initial, v2=failed-renewal, v3=rollback-of-v2; the certctl-managed-by + certctl-certificate-id provenance tags + future certctl-rollback-of metadata tag let an operator filter rollback artifacts. - Provenance tags identical to AWS ACM (certctl-managed-by=certctl + certctl-certificate-id=<mc-id>), automatically applied on every import. Key Vault carries tags forward across versions (unlike ACM which strips on re-import), so no separate AddTags call is required. - DeploymentRequest.KeyPEM held in agent memory only; PFX wrapping happens in-memory via software.sslmate.com/src/go-pkcs12. No disk write. Tests: - azurekv_test.go: 13-subtest happy-path + validation matrix — ValidateConfig (success / missing-vault-url / malformed-vault- url / missing-cert-name / invalid-credential-mode / reserved- tag rejection), DeployCertificate (fresh import / rollback-on- serial-mismatch / empty-key-rejected / no-client-rejected / SDK-error-surfaced), ValidateOnly (returns sentinel), ValidateDeployment (serial match / mismatch). - All tests use the NewWithClient injection seam; no real-Azure API calls. - go test -short -count=1 ./internal/connector/target/azurekv/... green. Wiring: - internal/domain/connector.go: TargetTypeAzureKeyVault = "AzureKeyVault". - internal/service/target.go: validTargetTypes set extended. - cmd/agent/main.go::createTargetConnector: AzureKeyVault case arm mirroring the AWSACM shape exactly. - cmd/agent/agent_test.go::TestCreateTargetConnector_AllSupported Types: AzureKeyVault added to the type matrix + the InvalidJSON matrix (16 supported target types now, up from 15). go.mod / go.sum: - github.com/Azure/azure-sdk-for-go/sdk/azcore v1.20.0 (direct). - github.com/Azure/azure-sdk-for-go/sdk/azidentity v1.13.1 (direct). - github.com/Azure/azure-sdk-for-go/sdk/security/keyvault/ azcertificates v1.4.0 (direct). The deprecated /keyvault/azcertificates path appears as a transitive indirect via Microsoft's microsoft-authentication-library-for-go; we use the new /security/keyvault/ path exclusively. Documentation: - docs/connectors.md "Azure Key Vault" section: config table, RBAC role recipe (off-the-shelf "Key Vault Certificates Officer" or custom role with 3 data-plane actions), AKS workload-identity / managed-identity / service-principal / default credential recipes, atomic-rollback contract + Azure-version semantics explanation, soft-delete caveat, App Gateway / Front Door Terraform attachment snippet, threat model carve-outs (no disk writes, mandatory provenance tags, no long-lived secrets in Config), 5-bullet procurement checklist crib. Out of scope (intentional, flagged in V3-Pro forward path): - Azure Front Door direct-attach (UpdateRoutingConfig — different Azure RBAC scope). - App Gateway / App Service auto-bind (V3-Pro auto-attach). - Soft-delete recovery (acm:RecoverDeletedCertificate-equivalent requires extra RBAC; V2 keeps minimum-permission surface). - GCP Certificate Manager (separate cloud, separate connector). Verified locally: - gofmt clean. - go vet ./internal/connector/target/azurekv/... ./internal/domain/... ./internal/service/... ./cmd/agent/... clean. - go test -short -count=1 ./internal/connector/target/azurekv/... ./cmd/agent/... green (all 16 supported target types instantiate via the agent factory).

### Azure Key Vault
|
||||||
|
|
||||||
|
The Azure Key Vault target connector deploys certificates into Azure Key Vault — the Azure-managed cert/secret store that Application Gateway / Front Door / App Service / Container Apps consume by KID URI. Rank 5 (Azure half) of the 2026-05-03 Infisical deep-research deliverable.

|
|-------|------|---------|-------------|
|
||||||
|
| `vault_url` | string | *(required)* | Key Vault DNS endpoint (`https://<vault-name>.vault.azure.net`). For US-Gov: `.vault.usgovcloudapi.net`; for China: `.vault.azure.cn`. |
|
||||||
|
| `certificate_name` | string | *(required)* | Cert object name in the vault (1-127 chars, alphanumeric + hyphens). Versions are auto-generated per import. |
|
||||||
|
| `tags` | object | | Tags applied at every import (Key Vault carries tags forward across versions, unlike ACM). Reserved keys `certctl-managed-by` + `certctl-certificate-id` are set automatically. |
|
||||||
|
| `credential_mode` | string | `default` | One of `default` / `managed_identity` / `client_secret` / `workload_identity`. See "Auth recipes" below. |
|
||||||
|
|
||||||
|
**RBAC role (minimum permissions):**
|
||||||
|
|
||||||
|
The off-the-shelf builtin role **Key Vault Certificates Officer** covers everything. For minimum-permission deploys, use a custom role with these data-plane operations on the vault scope (`/subscriptions/<sub>/resourceGroups/<rg>/providers/Microsoft.KeyVault/vaults/<vault-name>`):
|
||||||
|
|
||||||
|
```
|
||||||
|
Microsoft.KeyVault/vaults/certificates/import/action
|
||||||
|
Microsoft.KeyVault/vaults/certificates/read
|
||||||
|
Microsoft.KeyVault/vaults/certificates/listversions/read
|
||||||
|
```
|
||||||
|
|
||||||
|
**Auth recipes:**
|
||||||
|
|
||||||
|
- **AKS workload identity (`credential_mode: workload_identity`) — recommended for AKS deploys.** Annotate the agent's ServiceAccount with `azure.workload.identity/client-id=<app-id>`. The AKS cluster's OIDC issuer + the federated credential on the app registration handle token exchange; no long-lived secrets.
|
||||||
|
- **Managed identity (`credential_mode: managed_identity`) — recommended for VM / App Service deploys.** Assign a system-assigned or user-assigned managed identity to the host; certctl-server / agent picks it up via IMDS. Pin `credential_mode` rather than letting `default` fall through to env vars (defends against accidental local-dev creds leaking into production).
|
||||||
|
- **Service principal (`credential_mode: client_secret`).** Configure `AZURE_TENANT_ID` + `AZURE_CLIENT_ID` + `AZURE_CLIENT_SECRET` env vars on the agent. NOT recommended for production — long-lived client secret risk; rotate via Key Vault soft-delete recovery if leaked.
|
||||||
|
- **Default (`credential_mode: default` or unset).** SDK's `DefaultAzureCredential` walks env vars → managed identity → Azure CLI fallback. Useful for local-dev where the operator already has `az login` active.
|
||||||
|
- **Long-lived secrets in connector Config NOT supported** — same procurement-readability rule as AWS ACM.
|
||||||
|
|
||||||
|
**Atomic-rollback contract + Azure-version semantics:**
|
||||||
|
|
||||||
|
Every `DeployCertificate` snapshots the existing latest version via `GetCertificate(name, "" /* latest */)` BEFORE calling `ImportCertificate`. After import, the connector re-fetches the latest version and compares serial numbers. On serial-mismatch, the connector calls `ImportCertificate` again with the snapshotted CER bytes (re-PFX'd with the operator's key) — **as a NEW VERSION**. Key Vault doesn't support "version-restore" without soft-delete recovery (which we keep off the minimum-RBAC surface). The version history will show e.g. v1=initial, v2=failed-renewal, v3=rollback-of-v2; operators reading audit dashboards filter by tag.
|
||||||
|
|
||||||
|
**Soft-delete caveat.** V2 doesn't manage Key Vault soft-delete recovery. If a previous version was soft-deleted out-of-band (e.g. operator ran `az keyvault certificate delete`), the rollback re-imports the snapshot bytes as a new version rather than restoring the soft-deleted version. Operators alerting on rollback frequency should also watch for soft-delete events.
|
||||||
|
|
||||||
|
**App Gateway / Front Door attachment recipe:**
|
||||||
|
|
||||||
|
```hcl
|
||||||
|
data "azurerm_key_vault_certificate" "certctl_managed" {
|
||||||
|
name = "api-prod"
|
||||||
|
key_vault_id = azurerm_key_vault.main.id
|
||||||
|
}
|
||||||
|
|
||||||
|
resource "azurerm_application_gateway" "main" {
|
||||||
|
# ...
|
||||||
|
ssl_certificate {
|
||||||
|
name = "certctl-managed"
|
||||||
|
key_vault_secret_id = data.azurerm_key_vault_certificate.certctl_managed.secret_id
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Application Gateway / Front Door reference the cert by KID URI; certctl rotates the version under the same name, and the AGW / Front Door reference auto-resolves to the latest version (the SDK's behaviour when the KID points to `/certificates/<name>/<version>` vs `/certificates/<name>` differs — the latter auto-tracks "latest"; the former pins). Pin the version-less KID for auto-tracking renewals.
|
||||||
|
|
||||||
|
**Threat model carve-outs:**
|
||||||
|
|
||||||
|
- **Cert key bytes never written to disk on the agent.** PFX wrapping happens in memory (PKCS#12 via `software.sslmate.com/src/go-pkcs12`); the base64-encoded PFX is passed straight to the SDK's `ImportCertificate` call.
|
||||||
|
- **Provenance tags are mandatory.** Same `certctl-managed-by=certctl` + `certctl-certificate-id=<mc-id>` shape as AWS ACM. Operators identifying a stray Key Vault cert match against `certctl-managed-by`.
|
||||||
|
- **No long-lived Azure credentials in `Config`.** `Config` carries vault URL + cert name + operator tags + credential mode only. Auth is the Azure SDK credential chain.
|
||||||
|
- **`credential_mode: managed_identity` is the recommended production posture.** Defends against accidental env-var creds leaking into deployments where the host already has a managed identity assigned.
|
||||||
|
|
||||||
|
**Procurement checklist crib (paste into security review):**
|
||||||
|
|
||||||
|
- certctl uses Azure managed identity (or workload identity for AKS), not long-lived service-principal secrets.
|
||||||
|
- The cert key is held only in agent memory during the PFX wrap + import call; never written to disk.
|
||||||
|
- Every imported Key Vault cert is tagged with `certctl-managed-by=certctl` + `certctl-certificate-id=<mc-id>` for forensic traceability.
|
||||||
|
- Failed imports trigger automatic rollback by re-importing the snapshotted previous version's bytes; both outcomes are surfaced via Prometheus.
|
||||||
|
- The minimum RBAC role is 3 data-plane actions; Activity Log captures every API call for compliance audits.
|
||||||
|
|
||||||
|
**ValidateOnly contract.** Key Vault has no dry-run API; `ValidateOnly` returns `target.ErrValidateOnlyNotSupported`. Operators preview deploys via `ValidateConfig` + `az keyvault certificate show --vault-name <name> --name <cert>`.
|
||||||
|
|
||||||
|
Location: `internal/connector/target/azurekv/azurekv.go` + `internal/connector/target/azurekv/sdk_client.go` (azcertificates SDK wrapping) + `internal/connector/target/azurekv/azurekv_test.go` (happy-path + rollback + per-error contract tests).
