Wordpress Docker image for Plugin, Theme and MultiSite Development
This image is intended for local development only. It runs Nginx and PHP-FPM as the root user so that Docker volumes mounted at /var/www/html can be written by the server processes.
This is totally awesome for local theme and plugin development, and the worst of all possible worlds if it happens to end up on a real server, so don't. Just don't. :simple_smile:
I use this image with Docker Compose, thusly:
Install Docker and Docker Compose. Instructions will vary depending on your system.
Save the following in a repo somewhere as docker-compose.yml:
wordpress: image: gravityrail/wordpress volumes: - src:/var/www/html links: - db:mysql ports: - 8080:80 db: image: mariadb environment: MYSQL_ROOT_PASSWORD: example
Create a directory call "src" in the same directory as docker-compose.yml
docker-compose up. This will boot the WordPress and MariaDB docker images, install WordPress to your "src" directory, and run the server process.
open "http://$(boot2docker ip):8080", and install (for Linux, YMMV)
You can now install themes and plugins and mess with WordPress as much as you like!
Scripting the container with wp-cli
You can run the "wp" cli command as long as you include the "--allow-root" option, for example:
docker-compose run wordpress wp --allow-root plugin install hello-dolly
Nice, but noisy. On my own system (OS X, but this would work in Linux too), I created a wrapper for this using
alias in my
alias docker-wp='docker-compose run wordpress wp --allow-root'
Which turns the above command into:
docker-wp plugin install hello-dolly
Another example - let's create a new plugin!
docker-wp scaffold plugin my_super_plugin --plugin_name="My Super Plugin"
The magical, wp-cli way:
docker-wp core multisite-convert --title="My Blog Network"
One caveat of the configuration is that I use "folder" rather than "subdomain" MultiSite, for ease of use. I leave the necessary DNS shenanigans for local subdomain development as an exercise for the reader :simple_smile:
