Bedrock in a container

Layout of this repository

Check out the branches for each version of Bedrock supported by this repository.

Contents

This container includes:

• S6 Overlay
• Bedrock
• Composer
• WP CLI
• Node.js

Usage

See example

1. Create a Dockerfile with FROM weahead/bedrock:<tag>. Where tag is a version number like 1.6.3.

2. Make sure you add VOLUME /var/www/html to the end of your Dockerfile.

3. Create a folder named app next to Dockerfile.

4. Optionally, declare environment variables in docker-compose.yml files.

   Detailed info on environment variables and their values can be found in Bedrock documentation.

5. Place custom themes in folder app/themes.

6. Place custom plugins in folder app/plugins.

7. Use Composer to install non-custom plugins from WordPress Packagist via app/composer.json.

   This gives you a folder structure like this:

   .
   ├── Dockerfile
   ├── app
   │   ├── plugins
   │   │   ├── custom-plugin-1
   │   │   ├── custom-plugin-2
   │   │   └── ...
   │   └── themes
   │   │   ├── custom-theme-1
   │   │   └── ...
   │   └── composer.json
   └── ...
   

8. Build it with docker build -t <name>:<tag> .

Node.js service

This image has optional support for running a single Node.js service. If there is a package.json inside a theme folder, the image will run npm install in that folder during the build of a derivative image. Upon startup of a container from the built derivative image S6 will start a Node.js service that will run a command depending on the value of the environment variable NODE_ENV:

Value	Command
development	npm run dev
production	npm run start

This is useful for using Node.js based build systems like broccoli, grunt, gulp, etc. when developing the theme.

Also, when building a derivative image npm run build is executed as part of the image building to generate resources needed in production. So the package.json requires at least 3 scripts, start, dev, build. See example package.json

S6 supervision

To use additional services S6 supervision can be used. More information on how to use S6 can be found in their documentation.

The recommended way is to use COPY root / in a descendant Dockerfile with the directory structure found in example/root.

Notes for usage in production

It is probably a good idea to provide a new configuration file for opcache at /usr/local/etc/php/conf.d/opcache.ini. The configuration file included in this image is for development settings. A new configuration file can be provided by adding it in the Dockerfile that FROMs this image, or via another container that exposes configuration via Docker volumes.

Dockerfile example:

FROM weahead/bedrock:<tag>

COPY opcache.ini /usr/local/etc/php/conf.d/opcache.ini

Configuration container example with Docker compose:

bedrock:
  image: weahead/bedrock:<tag>
  volumes_from:
    - bedrock-conf
  ...

bedrock-conf:
  build: ./bedrock-conf
  ..

./bedrock-conf/Dockerfile:

# Reference same image that weahead/bedrock:<tag> uses as FROM
FROM php:5.6.21-fpm-alpine

COPY opcache.ini /usr/local/etc/php/conf.d/opcache.ini

VOLUME /usr/local/etc/php/conf.d
