What is Docker?— A CLI tool for simplifying creating, using, and sharing

Linux containers

— Linux containers leverage features in the Linux kernel and can be thought of as "OS virtualization"

— Combines daemon, client, image format all in single project

— Available from https://www.docker.com

Docker demo

What is rkt ("rock-it")?— An alternative to Docker, rkt is CoreOS'

implementation of the App Container specification ("appc")

— Designed to be modular/pluggable/extensible, secure, interoperable, natively integrated with init systems and orchestration tools

— Still very, very early (0.5.6 is latest release)

rkt demo

What is Photon?

— Lightweight, container-optimized Linux distribution created by VMware

— Designed for use not just as host OS, but also as "container OS"

— Similar projects/efforts include CoreOS, Project Atomic (RHEL/CentOS), Ubuntu Snappy Core

Photon demo

Cool...everyone's a

container expertnow, right?

What is Vagrant?

— A cross-platform, Ruby-based CLI tool for streamlining the use of VM environments (creation, provisioning, usage, & decommissioning)

— Supports multiple virtualization backends

— Great for testing, sharing with others, creating consistent environments

— Available from http://www.vagrantup.com
