Brainlunch über Docker.io Based on the Presenation of Joshua Barratt (http://serialized.net/2013/10/an-argument-for-containers-featuring-docker/)

2. “Docker is an open-source project to easily create
lightweight, portable, self-sufficient containers from any
application. The same container that a developer builds
and tests on a laptop can run at scale, in production, on
VMs, bare metal, OpenStack clusters, public clouds and
more.”

6. docker = lxc + golang + AUFS + cgroups
+ namespaces

7. lxc = Linux Container
Linux in a Linux
Isolated group of processes
Inside = VM, Outside = process
This is "chroot() on steroids"

8. Vorteile
Speed
Low Footprint
Virtualization!
Network
Filesystem
Isolation (Security, Resource)

9. cgroups = Control Groups
Like ulimit, but for groups of processes
... and with fine-grained accounting.

10. AUFS
“Writable single-system images”
oder
“Copy-on-write at the filesystem
level”

18. “IMHO docker is to paas what
chef(puppet) was to Iaas 4 years ago”

19. Application-centric
Automatic build
Versioning
Component re-use
Sharing
Tool ecosystem

25. CLI Adventure Time
