Docksal: Better than VMs
- 1. Docksal: Better than VMs by Leonid Makarov, Chief Architect @ FFW 04/25/2017 Drupal.org: @inqui Github: @lmakarov Twitter: @LeonidMakarov
- 2. Project onboarding Reality - it takes an unreasonable amount of time… • Missing/incomplete/outdated instructions • Tedious manual setup • VM and Vagrant boxes take forever/fail to build • Developers deal with sysadmin stuff instead of coding • Everyone’s setup is a snowflake • “It works on my loca!”
- 3. Project onboarding Here’s how we do project onboarding at FFW: $ git clone <project-repo> <folder> $ cd <folder> $ fin init Using Docker containers
- 4. Containers vs VMs Fundamental Differences • VMs • Hardware virtualization • Any host + any guest • Containers • OS virtualization • Linux host + Linux guest

- 8. Containers Pros • Efficiency - speed, resource use efficiency and density • Flexibility - add/remove services without provisioning • Consistency - pre-built service images • Portability - can run anywhere (local, CI, prod)
- 10. Docksal Setup Automated cross-platform one-line installer $ curl get.docksal.io | sh Linux • Native, no VM macOS and Windows • Single thin VM
- 11. Project initialization Project init script that you write once and run anywhere $ cat .docksal/commands/init ... fin exec drush sql-sync @stage @local fin exec drush <rr, updb, fra -y, cc, etc.> … $ fin init
- 12. Console tools in CLI $ fin exec <command> $ fin exec composer install $ fin exec drush uli $ fin exec drupal cr $ fin bash docker@cli:/var/www$ docker@cli:/var/www$ composer install
- 13. Zero Configuration $ cd my-project $ mkdir .docksal $ fin up Open http://myproject.docksal Default microservices • web - Apache • db - MySQL • cli - php-fpm, misc. console tools (composer, drush, dc, node, ruby...)
- 14. Simple and powerful Easy to customize stacks. More services available from: • Docksal library • Any image from Docker Hub $ cat .docksal/docksal.yml ... memcached: image: memcached environment: - MEMCACHED_MEMORY_LIMIT=128 ...
- 15. Notable Features • fin share - share your local environment on the internet • fin @project <cmd> - project aliases (similar to Drush remote aliases) • fin sqlc, sqli, sqld - MySQL console, import, dump • fin <custom-command> - script your own extensions • Offline installation mode (from a USB drive) • Good for conferences/trainings/etc. with limited connectivity
- 16. Recap: Path to success • Standardize • Same experience and tools anywhere, any platform • Use containers / Docker • No virtualization overhead (Linux) • No on-the-go provisioning • Flexible micro-service architecture • Automate, automate, automate • Minimize the number of steps needed to initialize a project
