What Developer needs

Production-like Quick Repeatable

Docker can● Deploy reliably & consistently● Everything will be exactly the same

– Distros– Software versions– Library dependencies

● If it works locally, it will work everywhere

Docker can● Deploy efficiently

– Laptop can run 10-100 containers easily– Server can run 10-1000 containers

● Containers can run at native speeds– http://www.slideshare.net/BodenRussell/kvm-and-

What is Docker?● Platform to help code, test and deploy

applications● Combine with

– Lightweight container virtualization– Work flows– Tooling

Containers vs. VMs

Host OS

Hypervisor

Container

Containers are isolated,but share OS and, whereappropriate, bins/libraries

Dockerfile● Dockerfile is instructions to build Docker image

– How to run commands– Add files or directories– Create environment variables– What process to run when launching container

Sample DockerfileFROM ubuntu:14.04
