fedi-feed-router/docker/build/Dockerfile.ci

# Image for CI: PHP and Composer only, no runtime server or frontend toolchain.
# Tests run against sqlite in memory (see .env.testing), so no database client
# or cache extension is needed.
#
# Published as fedi-feed-router-ci:php<version>-<revision>, not :latest. Runners
# cache mutable tags and will not re-pull them, so bump the revision in the tag
# and in ci.yml whenever this file changes.
#
# Debian-based rather than alpine: the alpine build hit repeated DNS resolution
# timeouts against codeload.github.com during composer install.
#
# gd is not declared in composer.lock but ThumbnailUploader calls it directly.
