Docker and WordPress/Bedrock

Several approaches already exist for using Docker with WordPress, including a couple of turnkey solutions and an official Docker container for WordPress, but the thing is, we use Bedrock in development and production, so we needed to take a different path.

The R&D behind this project continues, and you can read all about the long-form journey here. In a nutshell, this project aims to mate Docker with what we've found to be the best workflow (Bedrock) for making WordPress more like a true twelve-factor application.

Assumptions/Requirements

This is written assuming you want to develop WordPress (Bedrock) on a Mac using Docker to manage your local dev environment.

With that in mind, you'll need:

• Node/NPM (Make sure you have the latest stable version of Node!)
• Docker/Docker Toolbox
• Sequel Pro (Optional, but great if you want a GUI for your local DB)

N.B! You will only be able to use the guides herein if you have successfully completed at least the "Hello World" example in the Docker Toolbox docs. Go ahead, we'll wait.

How to Proceed

Great, let's get on with it, then!

# Start wherever you wanna keep your local dev sites. We like to just name our directory after the domain of the project.
$ git clone https://github.com/heygrady/docker-wordpress-starterkit.git yoursite.com && cd yoursite.com
$ npm install # currently only installs docker-pf
$ docker-machine start default || true && eval $(docker-machine env default)
# This pulls down a fresh WordPress/Bedrock installation
$ npm run bedrock:init
# Instead, you can pull down an existing Bedrock project you already use with this
$ npm run bedrock:init --docker-wordpress-starterkit:repo=git@gitlab.com:organization/example-name.git
# Start it on up, this will run php composer for you
$ npm run docker:up:daemon 
# Wait patiently for everything to initialize, might take a bit
$ open -a Google\ Chrome http://localhost:8080
# go through the install completely
# To make the DB persist, you need to run this command to shut the server down.
$ npm run docker:down:dump
# This restores the data when brought back up
$ npm run docker:up:daemon
# need a MySQL GUI?
$ npm run docker:db:open

Helpful Commands

You can see these new scripts in the package.json in this repository.

Command	Description
npm run docker:env	Sets the docker environment variables. This doesn't work exactly like you'd expect when you run it through NPM. It doesn't actually set the variables in your shell but in the environment that NPM is executing within. This is most useful when combined with other commands. NOTE: hmmmm. This needs explored.
npm run bedrock:init	Downloads a fresh copy of Bedrock WordPress to a local bedrock directory. OPTIONAL FLAG --docker-wordpress-starterkit:repo pulls down existing Bedrock project
npm run docker:pf	Starts the docker-pf port forwarding script in background mode.
npm run docker:pf:down	Kills the docker-pf port forwarding script.
npm run docker:build	Builds or rebuilds the images. Useful when you make changes to your Dockerfile or any of the files that are mentioned in your Dockerfile, like the docker-entrypoint.sh.
npm run docker:up	Starts the port forwarding script and starts your servers.
npm run docker:up:daemon	Starts your servers as a background daemon.
npm run docker:down	Stops the servers and stops the port forwarding script.
npm run docker:down:dump	Dumps the DB to your local and then stops the servers.
npm run docker:shell	Launches an interactive shell in the docker machine running WordPress.
npm run docker:shell:wordpress	Launches an interactive shell in the docker machine running WordPress.
npm run docker:shell:db	Launches an interactive shell in the docker machine running your DB.
npm run docker:db:dump	Zips up any existing dumps and then dumps the current schema and data to your local data directory.
npm run docker:db:open	Launches Sequel Pro with an open connection to your current WordPress MySQL database.
npm run docker:db:dump:schema	Zips up any existing schema dumps and dumps the current schema to your local data directory.
npm run docker:db:dump:data	Zips up any existing data dumps and dumps the current data to your local data directory.
npm run docker:db:roll:schema	Zips up any existing schema dumps and labels them with a timestamp in your local data directory.
npm run docker:db:roll:data	Zips up any existing data dumps and labels them with a timestamp in your local data directory.
