Data Sources

Middleware Manager can pull routers/services from Pangolin or directly from Traefik.

Active data source

• Set via Settings → Active Data Source or config.json (active_data_source).
• Pangolin uses /api/v1/traefik-config; Traefik uses /api/version checks.

Config file (mounted)

/app/config/config.json example:

{
  "active_data_source": "traefik",
  "data_sources": {
    "pangolin": {
      "type": "pangolin",
      "url": "http://pangolin:3001/api/v1",
      "basic_auth": { "username": "", "password": "" }
    },
    "traefik": {
      "type": "traefik",
      "url": "http://traefik:8080",
      "basic_auth": { "username": "", "password": "" }
    }
  }
}

Connection testing

• Uses a 5s timeout. Pangolin probe: /status. Traefik probe: /api/version.
• Basic auth is supported if provided.

When to switch

• Pangolin → Traefik: when you need direct Traefik state or Pangolin is unavailable.
• Traefik → Pangolin: when Pangolin is authoritative and should own router/service definitions.
