The document introduces various container technologies including Docker, rkt, VMware Photon, and Vagrant, emphasizing their roles in simplifying container management and virtualization. Docker is highlighted as a comprehensive tool for creating and sharing Linux containers, while rkt is presented as a modular alternative. Vagrant is showcased as a tool for managing virtual machine environments efficiently.

2. Before we start
— Get involved! Audience participation is requested and
encouraged.
— If you use Twitter, feel free to tweet about this session (use
@VMUGBe or hashtag #VMUGBe)
— Feel free to take photos or videos of today's session and share
them online
— A PDF copy of this presentation will be available online after
the event

5. 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

6. Docker demo

8. 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)

12. 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

14. Cool...everyone's a
container expert
now, right?

18. 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
