Docker

The application image is built FROM a pre-built runtime base (guystlr/by-night-base) that bakes in the PHP extensions and the MJML rendering extension (ext-mjml), so the app build never recompiles them. The base uses immutable version tags (php85-v1, php85-v2, …). The single source of truth is docker/base/VERSION, and the app's ARG BASE_IMAGE_TAG has no default — it must be passed explicitly on every build.

.github/workflows/build-base-image.yml publishes the base on main / manual dispatch — since published tags are immutable, it is a no-op when the docker/base/VERSION tag already exists. The release workflow passes BASE_IMAGE_TAG from docker/base/VERSION automatically and republishes a missing base tag itself before building the app, so releases are self-healing. PR validation is handled by validate-image-build.yml (builds base then app, no push).

For local builds, export the version first, then build/pull:

export BASE_IMAGE_TAG=$(cat docker/base/VERSION)
docker compose build
# pull (or build) the base it references:
docker pull guystlr/by-night-base:$BASE_IMAGE_TAG
docker build -t guystlr/by-night-base:$BASE_IMAGE_TAG docker/base

To change the base (e.g. add an extension): edit docker/base/Dockerfile and bump docker/base/VERSION (php85-v1 → php85-v2) in the same PR.

Hashed assets in production

Production (/apps/by-night.fr on the server) mounts the external volume by-nightfr_assets on public/build of the app and app-images services, so each release adds its hashed files next to the previous ones and never deletes any: pages opened before a deploy and emails sent months ago keep resolving. Docker only fills a named volume once, when it is created, so deploy.sh copies the new image's build into it right after the pull, before the rollout:

docker run --rm -v by-nightfr_assets:/mnt guystlr/by-night:stable cp -a /app/public/build/. /mnt/

services:
    app:
        volumes:
            - assets:/app/public/build

volumes:
    assets:
        external: true
        name: by-nightfr_assets

The volume was created by hand and seeded from the last Encore release, so the URLs of that era still resolve. The same one-liner with any image tag adds that release's files.
