rcourtman 8ad0cbbe26 Move static inline styles to classes the production CSP allows (#2642)
## Why

The production server sends `style-src 'self' 'nonce-...'` with no
`'unsafe-inline'` (`internal/api/security.go`). Solid compiles static
style values, such as `style="..."` or a literal entry of a `style={{
... }}` object, into template HTML. The browser reports each one as a
`style-src-attr` violation. Opening a row's inline detail on Machines or
Docker Images logged eight of them. The HelpIcon popover, the Assistant
typing dots and the alert threshold slider logged their own.

Chromium still applied the styles after Solid cloned the template, so
the visible effect there was console noise. Whether a stricter browser
applies them is not guaranteed. The Vite dev server allows inline
styles, so none of this showed up in development.

## What changed

- 24 drawer tab-panel `overflow-anchor` styles (ResourceDetailDrawer,
GuestDrawer, NodeDrawer, DockerHostDrawer, StoragePoolDetail,
DiskDetail) became the `[overflow-anchor:none]` class.
- The Assistant typing-dot delays became `[animation-delay:...]`
classes. `animate-bounce` already sets the 1s duration.
- ThresholdSlider uses `touch-none`.
- The HelpIcon popover keeps its dynamic position in `style` and takes
`min-w-[200px]` as a class.
- The boot-failure fallback in `index.tsx` is built from DOM nodes and
classes, which also stops the error text being parsed as markup.
- A new guard in `SharedPrimitives.guardrails.test.ts` compiles every
runtime `.tsx` that mentions `style` with the client-build Solid preset.
It fails on any `style` attribute or `<style>` element in the resulting
templates, nested `<template>` content included. The regex scans I used
first missed a mixed style object in HelpIcon; this check caught it.
- A note in `frontend-primitives.md` records the rule.

## Verification

- Production build of this branch embedded in a mock-mode backend that
serves the real nonce CSP, compared with an origin/main build on the
same setup. Checked at 1440x900 and 390x844, plus 1920/2560 for the
desktop thresholds table.
- Before: 8 violations per drawer open on `/standalone/machines` and
`/docker/images`, 3 on Docker host and Proxmox guest drawers, 1 on the
HelpIcon popover, 5 on the typing dots, 1 on the threshold slider.
- After: 0 violations on all of those, plus the Proxmox node drawer,
storage pool detail and disk detail.
- Computed styles match the old ones: `overflow-anchor: none` on every
visible panel, dot delays of 0/0.12/0.24s and 0/0.15/0.3s,
`touch-action: none`, popover `min-width: 200px`.
- Rows opened below the fold (drawer 215 to 351px past it) did not move.
Other drift readings were identical in both builds.
- Vitest: 933 files pass across the affected directories. The only
failure is `agentInstallCommand.test.ts`, which fails on macOS
regardless of this change.
- A new MessageItem test fails on origin/main and passes here.

Real-time Proxmox, Docker and Kubernetes monitoring that finds what needs attention.

Live demo · Documentation · Releases · Discussions

Pulse is a self-hosted monitoring workspace for Proxmox, Docker, Kubernetes, TrueNAS, physical and virtual machines, and early-access VMware vSphere environments. It combines live infrastructure state, history, alerts, recovery visibility, and scheduled health checks without requiring a conventional enterprise monitoring stack.

Pulse Proxmox workspace

Why Pulse

  • It watches between visits. Alerts and Pulse Patrol find failed backups, capacity pressure, restart loops, unhealthy containers, clock drift, and other problems that dashboards cannot surface when nobody is looking.
  • It keeps each platform familiar. Proxmox, Docker, Kubernetes, TrueNAS, vSphere, and machines have dedicated views, backed by one shared resource model for search, alerts, history, and investigation.
  • It stays operator-controlled. Credentials are encrypted at rest, API tokens are scoped, agent commands are disabled by default, and governed fixes require the configured policy and approval path.

Platform coverage

Platform Coverage
Proxmox VE, PBS, and PMG Nodes, guests, storage, backups, replication, Ceph, mail gateways, and alerts
Docker and Podman Hosts, containers, Compose projects, Swarm services, health, images, and updates
Kubernetes Clusters, nodes, workloads, pods, services, storage, and events through the unified agent
TrueNAS SCALE and CORE Pools, datasets, disks, snapshots, replication tasks, apps, VMs, and alerts
Linux, Windows, and macOS machines Host health, filesystems, networking, temperatures, RAID, and availability through the unified agent
VMware vSphere Early-access inventory, hosts, clusters, VMs, datastores, networks, snapshots, and recovery context; validate against your own vCenter before production use

Platform pages keep storage and recovery information beside the infrastructure it belongs to. Alerts, Actions, and Patrol remain cross-platform views.

Patrol: monitoring that does rounds

Pulse Patrol runs scheduled checks across the current state and recent history of your infrastructure. Community installations can use a local model or their own AI provider for watch-only analysis. Pulse Pro adds investigation and policy-bound fixes with approval, verification, and an audit trail.

Pulse Patrol attention queue

Pulse also includes an interactive Assistant and an MCP adapter for external clients such as Claude Code and OpenCode. Both sit on top of the same scoped inventory, metrics, alert, storage, and governed-action contracts.

Quick start

Choose an exact version from the latest release and keep that version pinned during installation.

Docker

docker run -d \
  --name pulse \
  -p 7655:7655 \
  -v pulse_data:/data \
  -e PULSE_DEPLOYMENT_METHOD=docker_run \
  --restart unless-stopped \
  rcourtman/pulse:vX.Y.Z

Open http://<your-ip>:7655 and follow the bootstrap-token setup. Docker host monitoring is provided by the unified agent; the Pulse server container does not need the Docker socket.

Proxmox LXC, Linux, and Kubernetes

The installer is signed. Verify install.sh against the pinned pulse-installer key before running it:

export PULSE_VERSION=vX.Y.Z
curl -fsSLO "https://github.com/rcourtman/Pulse/releases/download/${PULSE_VERSION}/install.sh" &&
curl -fsSLO "https://github.com/rcourtman/Pulse/releases/download/${PULSE_VERSION}/install.sh.sshsig" &&
ssh-keygen -Y verify \
  -f <(printf '%s\n' 'pulse-installer namespaces="pulse-install" ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIMZd/DaH+BldzOkq1A8KVTcFk73nAyrE8aJOyf7i00jm pulse-installer') \
  -I pulse-installer \
  -n pulse-install \
  -s install.sh.sshsig < install.sh &&
bash install.sh --version "${PULSE_VERSION}"

Paste the whole block: installation stops if either download or signature verification fails. Do not run the final command separately to bypass a failure.

The GitHub installer installs the Pulse server. Install and upgrade agents (including v5-to-v6 agent upgrades) with the per-host command generated under Settings → Infrastructure → Install on a host.

Do you need an agent?

Often not. Proxmox VE, PBS, and PMG are monitored through the Proxmox API with a read-only token, so nothing runs on the host and the generated setup script creates a privilege-separated monitoring user. Install the unified agent only where you want data the platform API cannot provide, such as host SMART health, temperatures, Docker hosts, or standalone machines.

The agent is operator-controlled by design. Command execution is off by default, the local listener binds to localhost, and generated systemd units ship hardened. On Linux, the installer's --least-privilege profile runs the service as a dedicated non-root user, with optional scoped sudo grants for the few collectors that need elevation. The agent security model documents exactly what the agent can and cannot do at each privilege level.

Important

GitHub release assets and rcourtman/pulse images are Community builds. Relay, Pro, and eligible legacy customers should use the private image or Linux archive provided by the Pulse download portal. Replacing a private Pro runtime with a public Community build removes its private runtime hooks.

Editions

  • Community — self-hosted monitoring, seven days of metric history, core SSO, update alerts, and Patrol with your own provider or local model.
  • Pro — Community plus Patrol investigation, governed fixes, ninety days of history, centralized agent profiles, RBAC, audit logging, and reporting.
  • MSP — for managed service providers: one Pulse Account running many client workspaces, each with an isolated Pulse runtime — separate dashboards, alerts, users, audit history, and reports. Free sixty-day two-client evaluation at Pulse for MSPs.

Relay is no longer sold. Existing Relay subscribers receive Pro features at their current price for as long as their subscription continues. Existing paired phones keep working until 31 March 2027. Relay connects the app, not the web UI. Use your own VPN or tunnel for remote web access. For phone alerts, add an ntfy, Gotify or Pushover destination and open Pulse in your phone's browser.

Core self-hosted monitoring is not gated by monitored-system or child-resource volume. See the runtime-aligned capability reference and current plans for details.

Development

Pulse uses Go 1.26 and a SolidJS/TypeScript frontend. The managed development runtime starts the frontend at http://127.0.0.1:5173 and proxies API and WebSocket traffic to the backend on port 7655.

npm ci
npm --prefix frontend-modern ci
npm run dev

Useful checks:

go test ./...
npm --prefix frontend-modern test
npm --prefix frontend-modern run type-check
python3 scripts/check_public_docs.py
