You can use Docker Compose to easily run WordPress in an isolated environment built with Docker containers. This quick-start guide demonstrates how to use Compose to set up and run WordPress. Before starting, you’ll need to have Compose installed.
Create an empty project directory.
You can name the directory something easy for you to remember. This directory is the context for your application image. The directory should only contain resources to build that image.
This project directory will contain a
docker-compose.yml file which will be complete in itself for a good starter wordpress project.
Tip: You can use either a
.yamlextension for this file. They both work.
Change directories into your project directory.
For example, if you named your directory
docker-compose.yml file that will start your
WordPress blog and a separate
MySQL instance with a volume mount for data persistence:
version: '3' services: db: image: mysql:5.7 volumes: - db_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: somewordpress MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: wordpress wordpress: depends_on: - db image: wordpress:latest ports: - "8000:80" restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: wordpress volumes: db_data:
The docker volume
db_datapersists any updates made by Wordpress to the database. Learn more about docker volumes
WordPress Multisite works only on ports
docker-compose up -d from your project directory.
This runs docker-compose up in detached mode, pulls the needed images, and starts the wordpress and database containers, as shown in the example below.
$ docker-compose up -d Creating network "my_wordpress_default" with the default driver Pulling db (mysql:5.7)... 5.7: Pulling from library/mysql efd26ecc9548: Pull complete a3ed95caeb02: Pull complete ... Digest: sha256:34a0aca88e85f2efa5edff1cea77cf5d3147ad93545dbec99cfe705b03c520de Status: Downloaded newer image for mysql:5.7 Pulling wordpress (wordpress:latest)... latest: Pulling from library/wordpress efd26ecc9548: Already exists a3ed95caeb02: Pull complete 589a9d9a7c64: Pull complete ...

Note: WordPress Multisite works only on ports
443. If you get an error message about binding
443(depending on which one you specified), it is likely that the port you configured for WordPress is already in use by another service.
At this point, WordPress should be running on port
8000 of your Docker Host, and you can complete the “famous five-minute installation” as a WordPress administrator.
Note: The WordPress site will not be immediately available on port
8000because the containers are still being initialized and may take a couple of minutes before the first load.
If you are using Docker Machine, you can run the command
docker-machine ip MACHINE_VM to get the machine address, and then open
http://MACHINE_VM_IP:8000 in a web browser.
If you are using Docker for Mac or Docker for Windows, you can use
http://localhost as the IP address, and open
http://localhost:8000 in a web browser.
The command docker-compose down removes the containers and default network, but preserves your Wordpress database.
docker-compose down --volumes removes the containers, default network, and the Wordpress database.
