Level 147

Portainer

Portainer runs on the tools VPS (100.81.122.65:9000). A Portainer agent runs on the web VPS (port 9001, bound to the Tailscale interface).

Access

Portainer UI: http://100.81.122.65:9000 — Tailscale access required.

Dashboard integration

The Portainer API at 100.81.122.65:9000 is reachable from the tools VPS but not from the web VPS’s Docker containers (different Tailscale node, bridge network isolation). The dashboard uses a fallback strategy:

  1. Try Portainer REST API (PORTAINER_URL + PORTAINER_TOKEN)
  2. If unreachable → fall back to Docker socket (/var/run/docker.sock)

This means the Portainer widget and page show real container data via the socket fallback even when the Portainer API is unavailable.

Configuration

/home/level147.net/.env
PORTAINER_URL=http://100.81.122.65:9000
PORTAINER_TOKEN=<portainer_api_token>

Generate the API token: Portainer UI → User settings → Access tokens.

Known limitation

Container actions (start/stop/restart) via the dashboard use the Docker socket directly on the web VPS — they only affect containers on that host. Cross-host container management requires the Portainer UI directly.
