Press-up

What is it?

Docker composable WordPress and MySql with automated AWS S3 backup and restore.

Requirements

• Docker (tested with v19.03.1)
• Docker compose (tested with 1.24.1)
• Node.js v8 or above (optional)

Environment variables

• MySql environment variables
• WordPress environment variables

Environment variables can be hard coded into docker-compose.yml, or loaded from
an environment variables file. See docker compose documentation for more information.
Tip: tools such as direnv can help manage your environment variables during development, and useful for keeping
secrets such as AWS credentials out of source control.

Commands

To ease getting started, the following npm commands are provided:-

• npm start
  • Uses docker-compose to spin up MySql and WordPress docker containers
• npm run stop
  • Stop MySql and WordPress docker containers
• npm run start:mysql
  • Only start the MySql server container
• npm run start:wordpress

  • Tip: when trying to connect to MySql instance already running on the same machine, set MYSQL_HOSTNAME=host.docker.internal
• npm run clean
  • Only use if you understand the risks
  • Destructive operation that forcefully prunes docker images, containers and volumes
  • Always make sure you have the appropriate backups first
  • Useful prior to building to ensure no cached layers are used, and images are downloaded again
• npm run build
  • Build MySql and WordPress container images
• npm run build:base
  • Only build the common base image
• npm run build:wordpress
  • Only build the MySql image
• npm run build:wordpress
