Get started playing with Craft CMS 3 in a few command lines with Docker

About CraftCMS : https://github.com/craftcms
Download Docker : https://www.docker.com/community-edition#/download

• Configure env: $ cp .env.example .env
• Start container: $ docker-compose up -d
• Enter container: $ docker-compose exec php bash
  • $ composer install
  • $ craft install

⚠️ Always run commands from container (ex: docker-compose exec php craft or docker-compose exec php composer require guzzlehttp/guzzle)

• Get the latest version number : https://github.com/craftcms/cms/releases
• Change craftcms/cms version in composer.json
• Start and enter container (cf: Quickstart)
• Run $ composer update
• Run $ craft migrate/all

• Run $ sudo nano /etc/hosts and add 127.0.0.1 myhost.local
• Modify .env and set SITE_URL=myhost.local + CRAFT_PORT=80
• Run $ docker-compose up
• If it fails make sure no service like Apache is running on port 80

The PHP and Nginx images are host on Docker Hub because first build takes a long time.
You can use volume in docker-compose.yml to override files in images
The docker images sources are available : https://github.com/atillay/docker-images/tree/master/craftcms3

If you change mysql credentials in .env you have to re-create mysql container:

• Database will be deleted, make a dump with PhpMyAdmin
• Remove db folder : $ rm -rf docker/db
• Run : docker-compose up
• Re-import your database on PhpMyAdmin

Release new version on Docker Hub :
$ docker build -t atillay/craftcms3-php ./docker/php
$ docker push atillay/craftcms3-php
