    "MYSQL_ROOT_PASSWORD=root",
    "MYSQL_DATABASE=wp_db",
    "MYSQL_USER=wp_user",
    "MYSQL_PASSWORD=wp_psw"    
  ],
  "HostConfig": {
    "PortBindings": {
      "3306/tcp": [
        {
          "HostPort": "3306"
        }
      ]
    },
    "RestartPolicy": {
      "Name": "always"
    }
  }
}

• Install phpMyAdmin.

Replace ${HOST_IP} with IP address of MySQL host.

{
  "Name": "phpmyadmin",
  "Image": "silintl/phpmyadmin:latest",
  "Env": [
    "MYSQL_HOST=${HOST_IP}"
  ],
  "HostConfig": {
    "PortBindings": {
      "80/tcp": [
        {
          "HostPort": "80"
        }
      ]
    },
    "RestartPolicy": {
      "Name": "always"
    }
  }
}

• Install Wordpress itself.

Replace ${HOST_IP} with IP address of MySQL host.

{
  "Name": "wordpress",
  "Image": "wordpress:latest",
  "Env": [
    "WORDPRESS_DB_HOST=${HOST_IP}",
    "WORDPRESS_DB_NAME=wp_db",
    "WORDPRESS_DB_USER=wp_user",
    "WORDPRESS_DB_PASSWORD=wp_psw"
  ],
  "HostConfig": {
    "PortBindings": {
      "80/tcp": [
        {
          "HostPort": "80"
        }
      ]
    },
