Dockerfile

# CI base image for the org's Ruby/Rails projects.
#
# Bakes Ruby + Node + Playwright (chromium) so CI jobs skip the per-run apt
# install, Node setup, and Playwright browser download. Gems and npm packages
# are intentionally NOT baked — they change too often and stay on CI caches in
# the consuming repo.
#
# Published to ghcr.io/lineofflight/ruby-node-playwright by .github/workflows/build.yml.

# Playwright chromium + its OS dependencies. Install to a fixed, HOME-independent
# path and expose it via ENV so the baked browsers are found at job time —
# GitHub Actions container jobs run with HOME=/github/home, not /root, so the
# default ~/.cache/ms-playwright location would otherwise miss. This mirrors the
# convention used by the official Playwright images. Pinned to the playwright
# version consumers resolve to; keep in sync to avoid a re-download at job time.
