Deploying WordPress using a Docker network

In this recipe, we will learn to use a Docker network to set up a WordPress server. We will create two containers, one for MySQL and the other for WordPress. Additionally, we will set up a private network for both MySQL and WordPress.

How to do it…

Let's start by creating a separate network for WordPress and the MySQL containers:

1. A new network can be created with the following command:

   $ docker network create wpnet
   

2. Check whether the network has been created successfully with docker network ls:

   $ docker network ls
   

   

3. You can get details of the new network with the docker network inspect command:

   $ docker network inspect wpnet
   

   

4. Next, start a new MySQL container and set it to use wpnet:

   $ docker run --name mysql -d \
   -e MYSQL_ROOT_PASSWORD=password \
   --net wpnet mysql
   

5. Now, create a container for WordPress. Make sure the WORDPRESS_DB_HOST argument matches the name given to the MySQL container:

   $ docker run --name wordpress -d -p 80:80 \
   --net wpnet\
   -e WORDPRESS_DB_HOST...
