Getting Started with Containers
- 1. Getting Started with Containers: Vagrant, Docker, rkt and VMware Photon Scott Lowe http://blog.scottlowe.org
- 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)
- 9. rkt demo
- 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
- 13. Photon demo
- 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
- 19. Vagrant demo
- 20. Q&A
