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 :)

• Boring! I just need to develop this website / software!

What is Docker?

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

• Accurately define environments
• Developers own all code (incl. OS-kinda)
• Deploy full docker container, e.g. to AWS
• What are Docker containers?

Containers v.s. VMs

Benefits of Docker!

Dev

• Accelerate
• Eliminate
• Collaborate

Deploy

• Ship Frequently
• Scale easily

• Accelerate Developer Onboarding
• Eliminate Environment Inconsistencies
• Easily Share and Collaborate

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!

• VM through Oracle’s VirtualBox
• Kitematic, the Docker GUI & Docker QuickStart shell
• Concept: Images v.s. Containers ≈ Classes v.s. Objects
• DockerHub => docker image repo

But... my DB server?

Options

• Use mySQLite?
• or a linked container?

Is this good enough?

• Extra management
• More commands

Solution: Docker Compose

Docker Compose file

						
version: '2'
services:
  web:
	build: .
	ports:
	- "5000:5000"
	volumes:
	- .:/code
	- logvolume01:/var/log
	links:
	- redis
  redis:
	image: redis
volumes:
  logvolume01: {}
