Quickstart: Compose and WordPress

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, make sure you have Compose installed.

Define the project🔗

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 contains adocker-compose.yml file which is complete in itself for a good starter wordpress project.

Tip: You can use either a .yml or .yaml extension for this file. They both work.

2. Change into your project directory. For example, if you named your directory my_wordpress:

[root@www ~]# mkdir -p /my_wordpress
[root@www ~]# cd /my_wordpress/

3.Create a docker-compose.yml file that starts your WordPress blog and a separate MySQL instance with a volume mount for data persistence:

[root@www my_wordpress]# cat docker-compose.yml 
version: '2'

services:
   db:
     image: mysql:5.7
     volumes:
       - /db_data:/var/lib/mysql
     ports:
       - "3306:3306"
     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
       WORDPRESS_DB_NAME: wordpress

Build the project🔗

Now, run docker-compose up -d from your project directory.

This runs docker-compose up in detached mode, pulls the needed Docker images, and starts the wordpress and database containers, as shown in the example below.

[root@www my_wordpress]# docker-compose up -d
Creating network "mywordpress_default" with the default driver
Creating mywordpress_db_1
Creating mywordpress_wordpress_1


[root@www my_wordpress]# docker images
REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE
wordpress                 latest              2da59c54a06a        5 days ago          543MB
mysql                     5.7                 718a6da099d8        7 days ago          448MB

[root@www my_wordpress]# docker-compose ps
         Name                        Command               State                 Ports               
----------------------------------------------------------------------------------------------------
mywordpress_db_1          docker-entrypoint.sh mysqld      Up      0.0.0.0:3306->3306/tcp, 33060/tcp 
mywordpress_wordpress_1   docker-entrypoint.sh apach ...   Up      0.0.0.0:8000->80/tcp  


[root@www my_wordpress]# ls /db_data/
auto.cnf    client-cert.pem  ibdata1      ibtmp1              private_key.pem  server-key.pem
ca-key.pem  client-key.pem   ib_logfile0  mysql               public_key.pem   sys
ca.pem      ib_buffer_pool   ib_logfile1  performance_schema  server-cert.pem  wordpress

[root@www my_wordpress]# docker network ls | awk 'NR==1 ||  $2=="mywordpress_default"'
NETWORK ID          NAME                  DRIVER              SCOPE
41aa3ed609bc        mywordpress_default   bridge              local

Bring up WordPress in a web browser🔗

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 is not immediately available on port 8000 because the containers are still being initialized and may take a couple of minutes before the first load.
