WordPress with MySQL

This example defines one of the basic setups for WordPress. More details on how this works can be found on the official WordPress image page.

Project structure:

.

docker-compose.yaml

services:
  db:
    # We use a mariadb image which supports both amd64 & arm64 architecture
    image: mariadb:10.6.4-focal
    # If you really want to use MySQL, uncomment the following line
    #image: mysql:8.0.27
    ...
  wordpress:
    image: wordpress:latest
    ports:
      - 8080:80
    restart: always
    ...

When deploying this setup, docker compose maps the WordPress container port 80 to port 8080 of the host as specified in the compose file.

ℹ️ INFO
For compatibility purpose between AMD64 and ARM64 architecture, we use a MariaDB as database instead of MySQL.
You still can use the MySQL image by uncommenting the following line in the Compose file
#image: mysql:8.0.27

Deploy with docker compose

❯ docker compose up -d

Expected result

Check containers are running and the port mapping:

❯ docker ps
CONTAINER ID   IMAGE                  COMMAND                  CREATED         STATUS         PORTS                  NAMES
0195bf240f0b   wordpress:latest       "docker-entrypoint.s…"   4 seconds ago   Up 2 seconds   0.0.0.0:8080->80/tcp   demo-wordpress-1
022e87ece6e0   mariadb:10.6.4-focal   "docker-entrypoint.s…"   4 seconds ago   Up 3 seconds   3306/tcp               demo-db-1

Navigate to http://localhost:8080 in your web browser to access WordPress.

Stop and remove the containers

$ docker compose down

To remove all WordPress data, delete the named volumes by passing the -v parameter:

$ docker compose down -v
