WordPress with MariaDB and dump

This example defines a wordpress container architecture.

The architecture is prepared in Dockerfiles where the MariaDB consumes a dump and the Apache gets supplied a Wordpress folder structure in the document root.

It is based on WordPress image page.

When deploying this setup, docker compose maps the WordPress container port 9875 to port 9875 of the host as specified in the compose file.

Prerequisites

This example uses our Puppeteer Chrome Container and will download it on the first measurement if you did not already pull it.

If you do want to alter this container you can also build it yourself from Puppeteer Chrome Container. Only be sure to update the usage_scenario.yml with the local image identifier.

Deploy with docker compose

docker compose up -d

Set hostnames for local debugging

Please set in /etc/hosts the following entry: 127.0.0.1 gcb-wordpress-apache

Expected result

Check containers are running and the port mapping:

$ docker compose ps -a
NAME                    IMAGE                   COMMAND                  SERVICE                CREATED              STATUS              PORTS
gcb-wordpress-apache    gcb_wordpress_apache    "docker-entrypoint.s…"   gcb-wordpress-apache   About a minute ago   Up 4 seconds        80/tcp, 0.0.0.0:9875->9875/tcp, :::9875->9875/tcp
gcb-wordpress-mariadb   gcb_wordpress_mariadb   "docker-entrypoint.s…"   gcb-wordpress-mariadb   7 minutes ago        Up 7 seconds        3306/tcp

Navigate to http://gcb-wordpress-apache:9875 in your web browser to access WordPress.

Stop and remove the containers

docker compose down

Once you are finished testing and want to remove all WordPress data you have to remove the image and delete the layer cache since we copy the data in:

docker compose down -v
docker rmi -f gcb_wordpress_mariadb
docker system prune --volumes

Peculiarities

The MariaDB database takes a long time to boot.

Therefore a sleep 20 is in the setup-commands of the usage_scenario.yml so that Puppeteer will not
get a database connection error from Wordpress.

Changing the data in the admin

Go to http://gcb-wordpress-apache:9875/wp-admin/ and use:

  • Username: arne
  • Password: arne
