Share how Lithium deployed Containers on
OpenStack and hopefully provide a pattern
that can be followed for your journey.

3. OUR JOURNEY TO CONTAINERS
• Cloud-platform running on OpenStack and AWS
• Microservices
• DevOps
3

4. WHY CONTAINERS AND OPENSTACK?
• OpenStack provides a stable platform to innovate.
• OpenStack bridged gaps in the container story.

5. HERE’S WHAT WE DIDN’T WANT TO HAPPEN

6. THE RIGHT TECHNOLOGY AT THE RIGHT TIME
• No one ever got fired for running VMs
• Who doesn’t love whales?
• You know your work loads
• There isn’t a problem. Why are we doing this?
6

7. THE CONTAINER VALUE PROP
• Developer productivity
• Portable
• Multi-cloud deployments
• Lightweight orchestration

9. CONTAINER STRATEGY
Incremental revolution!

10. CONTAINER STRATEGY
• Leave the monolith alone
• Staying in the “success zone”
• Overlay container orchestration on OpenStack
and AWS
• Had to address container security
10

11. BUILDING CLOUD-NATIVE APPLICATIONS
• Containers demanded a change in thinking
• Tooling
• Standardized deployments
11

12. CURRENT STATE OF PLAY
• Kubernetes on OpenStack
• Standard microservice deployment pipeline
• Moving workloads - The big payoff is coming
• CI/CD pipeline overhaul
• Multi-cloud
• Happy Developers

13. HERE’S HOW WE DID IT
• First iteration was Kubernetes cluster on
Openstack VMs using static routing to deliver
cluster connectivity.
• This provided a cluster that developers can deploy
apps to and network connectivity to allow external
access to the cluster.

14. BOLTING IT ALL TOGETHER – STATIC ROUTING

15. GREAT! IS THAT ALL?
• How about we utilize the same SDN that powers
our Openstack to run out Kubernetes networking?
• Kubernetes cluster running on Openstack VMs
using OpenContrail as the SDN.

17. AS PROMISED
• Here’s how I built it

18. FUTURE STATE
• Containerize all the things?
• Stick with Docker?
• Libnetwork/CNI?
• Persistent storage?
• Kubernetes, Mesos?
• PaaS? OpenShift?
18

19. DEAD BODIES
• The Docker problem
• Workflow disruption
• Complexity shifts back to Ops

• Kuryr

21. WISH LIST
• I would like to use OpenStack APIs to provide
networking, storage, images.
• Provide persistent container storage via Cinder.
• Make Glance/Swift a container registry.
• Container registry as a service.
