docs/Docker & Kubernetes/Docker/Docker Compose/Firefox.md

Purpose: Sometimes you just want an instance of Firefox running on an Alpine Linux container, that has persistence (Extensions, bookmarks, history, etc) outside of the container (with bind-mapped folders). This is useful for a number of reasons, but insecure by default, so you have to protect it behind something like a Keycloak Server so it is not misused.

Traefik Reverse Proxy Configuration

If the container does not run on the same host as Traefik, you will need to manually add configuration to Traefik's dynamic config file, outlined below.

http:
  routers:
    work-environment:
      entryPoints:
        - websecure
      tls:

      service: work-environment
      rule: Host(`work-environment.bunny-lab.io`)
      middlewares:
        - work-environment  # Referencing the Keycloak Server
