# Image for CI: PHP, Composer and the extensions the suite needs. No runtime
# server; the frontend build runs in its own job on a node image.
#
# Published as incr-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: ffr hit repeated DNS resolution timeouts
# against codeload.github.com on the alpine build.
#
# pdo_mysql, not sqlite: the migration tests query information_schema and
# exercise MySQL-specific DDL, so CI runs against a real mysql:8.0 service.
