Base Images

• Base Image
• PHP
• Magento

Build everything:

# Fundimentally, this is all it takes:
docker buildx bake --provenance=false --push --progress=plain

# But we have some test wrappers to automatically test and push
./test && ./bake

Architecture of the Containers

Based on runit. It runs multiple processes internally, and monitors them. In the /etc/services.d/ directory you'll find the following services at time of writing:

• alpine-*-base: Base image
  • /etc/services.d/logs/: Log service, which collects logs from the other services and writes them to files.
    • Setting the envvar LOG_PATHS to a space-seperated list of paths will make the log service collect logs from those paths and write them to stdout.
  • /etc/services.d/splash/: Splash service, which is a simple web server that serves the splash page.
  • /etc/services.d/cron/: Cron service.
• php-*-base: PHP flavoured base image
  • /etc/services.d/nginx/: Nginx service.
  • /etc/services.d/php/: PHP-FPM service, which runs the PHP application itself.
• php-*-node-base: PHP flavoured base image with Node.js support
  • /etc/services.d/npm-babysitter/: Monitors permissions on the node cache directories and fixes them if they change.
  • /etc/services.d/npm-watcher/:
    • Similar to the logs service, setting the envvar NPM_WATCH_PATHS will make the npm watcher run npm run watch in those paths.
    • [ WARNING ]: This is currently busted.
• magento-*-base: Magento flavoured base image
  • /etc/services.d/magento/: Magento service, which runs the Magento application.
    • Fixes cache permissions, and runs any scripts loaded into /etc/services.d/magento/tasks.d/ to get your Magento application going and touches /etc/services.d/magento/done upon completion.
• java-*-base: Java flavoured base image
• java-war-machine-*-base: Java War Machine flavoured base image
  • /etc/services.d/java/: Java service runner, which runs any .war files placed into /app

Each directory contains a run script that starts the service. The run script is executed by runit when the container starts. If the run script exits, runit will restart it, unless there is a finish script. The finish script will get the exit code of run as its $1 argument. The finish script can decide to sleep forever or exit to restart the service. More can be read in the runit documentation particularly runsv and runsvdir
