What is this talk about?

  • How? complex dev environments...
  • What? Vagrant; Puppet, Chef, Ansible...etc.
  • Confused! I’m not an admin...
  • Boring! Waste of time.
  • Enter Docker :)

What is Docker?

    An open platform for distributed applications for developers and sysadmins
  • Agility
  • Control
  • Portability

Containers v.s. VMs

Benefits of Docker!

  • Eliminate
  • Collaborate

Deploy

  • Ship Frequently
  • Scale easily

Docker in the Cloud

Getting started

  • Mac / Win users: install Docker Toolbox ;
    • boot2docker
    • CLI client & Docker Machine
    • Docker Compose: docker-compose
    • Kitematic (GUI) & Docker QuickStart shell
  • DockerHub
  • Demo!

But... my DB server?

Options

  • Use mySQLite?
  • or a linked container?

Is this good enough?

  • Extra management
  • More commands

Solution: Docker Compose

“a tool for defining and running multi-container Docker applications”
  • Compose file docker-compose.yml
  • Wrapper CLI docker-compose

    • Docker Compose file

    A docker-compose.yml looks like this:
    						
version: '2'
services:
  web:
	build: .
	ports:
	- "5000:5000"
	volumes:
	- .:/code
	- logvolume01:/var/log
	links:
	- redis
  redis:
	image: redis
volumes:
  logvolume01: {}

    Using Docker Compose

    • Configure yml file
    • Up containers! docker-compose up -d
    • Run docker-compose exec container_name drush status
    • Stop docker-compose stop
    • Destroy docker-compose destroy

    Demo

    Conclusion

    • Docker is great
    • Try it out
    • Open any issues on the GitHub repo
