# All services run the same image, which is built once by the `setup` service.
# The other services reference it via this anchor and set `pull_policy: never`
# so Compose uses the locally built image instead of trying to pull it from a
# registry on a cold start (which it does concurrently with the build).
x-app: &app
  image: alchemy-dummy-app
  pull_policy: never

# Gems and node_modules are baked into the image. Gems live outside the
# `.:/workspace` bind mount, so they are served straight from the image with no
# volume. node_modules sits under the bind mount, so an anonymous volume
# (`- /workspace/node_modules`) shadows the host directory and surfaces the
# image's copy instead of the host's (which has platform-specific binaries).
# After changing dependencies, rebuild the image; refresh node_modules with
# `docker compose up --build --renew-anon-volumes`.
#
# USER_ID/GROUP_ID select the uid/gid of the image's `alchemy` user, which has to
# own the `.:/workspace` bind mount to be able to write into it. `bin/start` sets
# them from the host user, so the documented entry point needs no configuration.
