Requirements

Make sure you have the latest versions of Docker and Docker Compose installed on your machine.

Clone this repository or copy the files from this repository into a new folder. In the docker-compose.yml file you may change the IP address (in case you run multiple containers) or the database from MySQL to MariaDB.

Make sure to add your user to the docker group when using Linux.

Configuration

Edit the .env file to change the default IP address, MySQL root password and WordPress database name.

Installation

Open a terminal and cd to the folder in which docker-compose.yml is saved and run:

docker-compose up

This creates two new folders next to your docker-compose.yml file.

• wp-data – used to store and restore database dumps
• wp-app – the location of your WordPress application

The containers are now built and running. You should be able to access the WordPress installation with the configured IP in the browser address. By default it is http://127.0.0.1.

For convenience you may add a new entry into your hosts file.

Usage

Starting containers

You can start the containers with the up command in daemon mode (by adding -d as an argument) or by using the start command:

docker-compose start

Stopping containers

docker-compose stop

Removing containers

To stop and remove all the containers use thedown command:

docker-compose down

Use -v if you need to remove the database volume which is used to persist the database:

docker-compose down -v

Project from existing source

Copy the docker-compose.yml file into a new directory. In the directory you create two folders:

• wp-data – here you add the database dump
• wp-app – here you copy your existing WordPress code

You can now use the up command:

docker-compose up

This will create the containers and populate the database with the given dump. You may set your host entry and change it in the database, or you simply overwrite it in wp-config.php by adding:

define('WP_HOME','http://wp-app.local');
define('WP_SITEURL','http://wp-app.local');

Creating database dumps

./export.sh

Developing a Theme

Configure the volume to load the theme in the container in the docker-compose.yml:

volumes:
  - ./theme-name/trunk/:/var/www/html/wp-content/themes/theme-name

Developing a Plugin

Configure the volume to load the plugin in the container in the docker-compose.yml:

volumes:
  - ./plugin-name/trunk/:/var/www/html/wp-content/plugins/plugin-name

WP CLI

The docker compose configuration also provides a service for using the WordPress CLI.

Sample command to install WordPress:

docker-compose run --rm wpcli core install --url=http://localhost --title=test --admin_user=admin --admin_email=test@example.com

Or to list installed plugins:

docker-compose run --rm wpcli plugin list

For an easier usage you may consider adding an alias for the CLI:

alias wp="docker-compose run --rm wpcli"

This way you can use the CLI command above as follows:

wp plugin list

phpMyAdmin

You can also visit http://127.0.0.1:8080 to access phpMyAdmin after starting the containers.

The default username is root, and the password is the same as supplied in the .env file.
