Combined Dockerfile for single-container hosting

[AdamLassiter]

Hi! Thanks for building and maintaining Ogres. I’ve been setting up a self-hosted instance behind Traefik and Cloudflare Tunnel, and I ended up making a small deployment-oriented change that may be useful upstream.

The current Docker setup splits the app across separate frontend, backend, and nginx services, with the nginx image also cloning the gh-pages branch for release fallback assets. That works well for the existing compose flow, but it is a little awkward in environments where the operator wants a single deployable container behind an existing reverse proxy.

I’ve put together an alternative combined Dockerfile that:

• builds the ClojureScript frontend release assets
• builds the Clojure backend uberjar
• serves the landing page, /play, /release/*, and /releases.txt through nginx
• proxies /ws internally to the backend on 127.0.0.1:8090
• runs nginx and the backend in one final image
• avoids cloning gh-pages at image build time, so the image is built from the checked-out repository contents

The intended use case is self-hosting behind something like Traefik/Caddy/nginx where TLS is already terminated outside the app container, for example with Cloudflare Tunnel in front.

One implementation detail I hit: with current npm, the root package-lock.json appears to be out of sync around esbuild’s optional platform packages, so npm ci fails in a fresh container build unless the lock is refreshed first. I handled that in my local Dockerfile build layer, but I wanted to flag it separately because it may be worth addressing directly in the lockfile.

Would you be open to a PR adding this as an optional deployment target under deploy/, without changing the existing multi-service Docker setup?

For what it's worth, my docker-compose.yml can then simply be:

services:
  ogres:
    build:
      context: ogres
      dockerfile: ./deploy/combined.dockerfile
      args:
        VERSION: "v0.25.2"
        PUBLIC_SOCKET_URL: "wss://ogres.${ROOT_DOMAIN}/ws"
    container_name: ogres
    restart: always
    labels:
      traefik.http.services.ogres.loadbalancer.server.port: 80

and traefik.yml:

http:
  routers:
    ogres:
      rule: Host(`ogres.${ROOT_DOMAIN}`)
      service: ogres@docker
