Caddy Server with PHP-FPM

This creates a Docker container running PHP on Alpine Linux.

Why another container?

I just wanted all the PHP libraries I tend to use.

It also supports running commands before and after starting PHP-FPM and running composer install before running PHP-FPM.

It also includes the ([ssmtp] package so that after its configured you can use PHP's mail() function.

Run Example

  • docker run -p 80:80 -p 443:443 -v /var/www/html:/srv stevepacker/caddy-php7

Docker Environment Variables

  • PHP_BEFORE: command(s) to run prior to running composer install and php-fpm
  • PHP_COMPOSER_FLAGS: flags to include with composer install (ex: --prefer-dist --no-dev)
  • PHP_AFTER: command(s) to run after composer install and php-fpm

Docker Volumes

  • /srv: Base directory. If a composer.lock is in this directory, composer install will automatically run prior to starting php-fpm
  • /root/.caddy: When an SSL is generated, files are stored here by Caddy.
  • /etc/Caddyfile: If you intend to include your own Caddyfile, mount it here.
  • /etc/ssmtp/ssmtp.conf: If you intend to use PHP's mail() function, configure this file.
  • /etc/ssmtp/revaliases: Another configuration file for ssmtp
