CI base image bundling Ruby, Node, and Playwright (chromium) for the org's Ruby/Rails projects. Lets CI jobs skip the per-run apt install, Node setup, and Playwright browser download.

Published to ghcr.io/lineofflight/ruby-node-playwright:latest.

• Ruby 4.0.5 (rubylang/ruby:4.0.5-dev-noble base)
• System packages: libpq-dev, libyaml-dev, pkg-config
• Node.js 24 (current Active LTS)
• Playwright 1.60.0 chromium + OS dependencies

Gems and npm packages are intentionally not baked — they change too often and stay on CI caches in the consuming repo.

jobs:
  checks:
    runs-on: self-hosted
    container:
      image: ghcr.io/lineofflight/ruby-node-playwright:latest
    steps:
      # ... gems from cache + bundle, npm ci, then run checks/tests

Keep the consumer's playwright npm version in sync with the baked version (1.60.0) so the browser isn't re-downloaded at job time.

.github/workflows/build.yml rebuilds and pushes on every push to main, weekly (base-image security patches), and on manual dispatch. Bump the Ruby / Node / Playwright versions by editing the Dockerfile.
