Docker (Arcane)

Web dashboard for inspecting the host's Docker containers and stacks · https://docker.fmm.house

What it's for

Arcane is a web UI for seeing what Docker is doing on the host — which containers are running, whether they're healthy, their logs, and the images and stacks behind them. It talks to Docker through a read-only socket proxy, so it's built mainly for looking, not changing: most write actions (start/stop/delete) are blocked at the proxy. This is an admin tool for keeping an eye on the fleet.

Getting in

  • Open: https://docker.fmm.house — on the home Wi-Fi/LAN, or from anywhere with Tailscale connected.
  • Sign in: Log in with your Arcane admin credentials. It's admin-only — there's nothing here for non-operators.

How to use it

Check running containers and health

  • The Containers view lists everything Docker knows about, with status (running/exited) and health where a healthcheck is defined.
  • Sort or filter to spot anything that's stopped, restarting, or unhealthy at a glance.
  • Click a container to see its details: ports, mounts, environment, and the image it's based on.

Read logs

  • Open a container and switch to its Logs tab to read recent output.
  • Use it to diagnose crash loops or errors without SSHing into the host — tail the log and watch new lines arrive.

Inspect images and stacks

  • Images shows what's pulled locally, their tags, and sizes — useful for confirming a version bump landed.
  • Stacks / Compose gives the higher-level view: which services belong to which compose project and how they're doing together.

Tips

Note

The read-only socket proxy is intentional. Buttons for start/stop/restart/remove may be present but will fail or be disabled — that's expected, not a bug. Do container lifecycle changes from the host (or the code.fmm.house terminal) instead.

  • Great first stop when something seems off: check container health and logs here before digging in over SSH.
  • For deeper monitoring and history, pair this with the dedicated monitoring stack — Arcane is best for a quick live look at Docker itself.
