Container History

●  1988: FreeBSD Jail●  2005: Solaris Zones●  2005: OpenVZ●  2008: LXC●  2013: Docker●  2014: Rocket●  2015: Wocker :-)

A Container ...

●  Uses Kernel Namespaces●  Uses Linux Cgroups●  Uses Container Image (e.g. Docker Image)●  Has a Lifecycle●  Is a slice of the Kernel●  Is inexpensive and fast●  Could be unsecureo  docker daemon runs as root (libvirt

libcontainer)o  RKT is daemon less (systemd nspawn)

Magnum Architecture

●  There are 7 type of objects in magnum○  Bay: collection of nodes○  BayModel: template for bays (define coe)○  Node: VM or bare-metal running MicroOS○  Pod: collection of containers○  Service: abstraction of pods + policy to

access pods○  ReplicationController: manages pods and

makes sure a certain number of pods are running

○  Container (a docker container)

Magnum has the potential ...

●  To become a Magnum Opus●  To provide cloud ready apps and services●  To manage Multi Tenant aware Container

Topologies●  To use OpenStack as a first class citizen for

container technology●  To help people helping people

About Kolla

●  Containers for OpenStacko  Stackforge Projecto  Docker Container based OpenStack

deployment (image based)o  Containerizing OpenStack Serviceso  Solves manageability and availability

problemso  Offers atomic upgrade of a running

system with minimal interruption in service (10 seconds)
