Lightweight PHP-FPM & Nginx Docker Image for WordPress
This is maintained repository. We use this project in production and recommend this for your projects too. This container doesn't have mysql or email, you need to provide them from elsewhere. This can be other container or your host machine.
Aren't you only supposed to run one process per container?
We think that docker container should be small set of processes which provide one service rather than one clumsy process. This container uses s6-overlay in order to run php-fpm and nginx together.
Container layout
Mount your wordpress project into:
/data/code
Your project should define web root in:
/data/code/web
This is the place where nginx will serve requests. This is compatible with bedrock layout.
Cron jobs
You can place cron file in /data/code/tasks.cron. This is symlinked to crond and run as user nginx.
For example:
# do daily/weekly/monthly maintenance
* * * * * echo "test log from: $(whoami)..." >> /tmp/test.log
Environment Variables

Remember to set DB_NAME, DB_PASSWORD and DB_USER and use these variables in your wp-config.php. These are automatically added as envs in php context.
Email variables
SMTP_HOST
This variable changes the host where container tries to send mail from. By default this is docker host 172.17.0.1.
