Wordpress with MySQL & phpMyAdmin - Add external network "web" before deployment. Ready to add reverse proxy and remove both WP and PMA from external facing network.

wordpress_docker_pma.md

Wordpress on Docker

This file will setup Wordpress, MySQL & PHPMyAdmin with a single command.

This files also uses 2 networks. I did this so that nginx or another reverse proxy could be added to the stack and then the WP container could be taken off the outward facing "web" network. I might add another more simple config later.

Steps:

Create a docker network called "web":

$ docker network web

Create a new folder to house your docker-compose file and mount our WP volumes in. I will be using $HOME/wordpress_docker/:

 $ cd && mkdir wordpress_docker 
 $ cd wordpress_docker	

Add the code below to a file called "docker-compose.yaml" and run the command:

$ docker-compose up -d

After that you can go to http://localhost:8080 to finish setting up wordpress. PHPMyAdmin is available at http://localhost:8081
