Run The Container

Create and Run The Container

If you run and want to link Nginx container, make sure you created and run this PHP-FPM the container before running this Nginx container. Make sure the /www volume in PHP-FPM container is mapped.

  • The first -p argument maps the container's port 9000 to port 9000 on the host and used for communication between Nginx and PHP-FPM.
  • --name argument sets the name of the container, useful when starting and stopping the container.
  • The -v argument maps the /home/user/public_html directory in the host to /www in the container with read/write access (rw).
  • -d argument runs the container as a daemon.

Stopping The Container

docker stop phpfpm

Start The Container Again

docker start phpfpm

PHP CLI

To ease the job, make alias for PHP-CLI. Add this line to ~/.bashrc so we can call it as regular php command.

alias php='docker run --rm --name=php-cli -v $(pwd):/www matriphe/alpine-php:cli php'
