## Setup for using Docker containers with Wordpress and MYSQL
- New application
  - Run command
    - `docker-compose up -d`
- Existing application
- To ensure database container is loaded before Wordpress container is started
you **MUST** start containers individually the first time development environment is setup
  - Start database container
    - `docker-compose up -d db - Replace db with the name of your database container`
  - Wait until database is running and loaded (10s is usually more than enough time)
  - Start your wordpress container
    - `docker-compose up -d wordpress - Replace db with the name of your database container`
