Features

Plugins and other dependencies

Getting started

You only need two files:

docker-compose.yml
default.conf

Add backups/.ignore to your .gitignore file. This file is used for automatic db restores. Files listed in backups/.ignore do not get imported on start up.

docker-compose

nginx configuration

Create a file called default.conf in to your project directory:

# default.conf

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name localhost;

    index index.php index.html;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /var/www/html/web;
    charset utf-8;

    # Root directory location handler
    location / {
        try_files $uri/index.html $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        try_files $uri $uri/ /index.php?$query_string;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass craft:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

Plugins

Add your plugins to the environment variable DEPENDENCIES. A script then automatically adds or removes those dependencies when you create the container.

In a docker-compose file:

volumes:
  - ./path/to/plugin:/plugins/plugin # If you want to use a local plugin with composer

environment:
  DEPENDENCIES: >- # additional composer packages
    craftcms/redactor:2.0.1
    [vendor/package-name:branch-name]https://url-to-the-git-repo.git # branch-name needs to be prefixed with 'dev-'. (e.g. dev-development for branch development)
    [vendor/package-name:version]/path/to/volume # Version as 1.0.0

You can add plugins from a public Git Repo, or from a local folder on your machine as Well. For local Plugins take care that you added a volume so that docker can use the plugin.

If you change your dependencies, run docker-compose down && docker-compose up to remove and recreate your container.

Import database

Create another volume which gets mounted to /var/www/html/storage/backups

    volumes:
      - ./backups:/var/www/html/storage/backups

When you create a db dump from within your Craft CMS CP, a sql file gets automatically saved in this folder and you can add it to your git repository.

On startup the docker image looks for sql or zip files in this folder and imports them, unless its filename is listed in a special file called .ignore. This prevents importing the same file twice.

After successfully importing the db dump, this file gets added to .ignore, so you don't have to worry about that.

Redis

Create config/app.php and add the following lines:

return [
    'components' => [
        'cache' => [
            'class' => yii\redis\Cache::class,
            'defaultDuration' => 86400,
            'redis' => [
                'hostname' => getenv('REDIS_HOST'),
                'port' => 6379,
                'database' => 1,
            ],
        ],
    ],
];

Add yiisoft/yii2-redis to your DEPENDENCIES env variable and create another volume for your redis configuration

volumes:
  - ./config/app.php:/var/www/html/config/app.php

Add a redis service to your docker-compose.yml

redis:
  image: redis:4-alpine
  volumes:
    - redisdata:/data

Finish setup

Run docker-compose up and visit http://localhost/admin. Voilà!
