This document discusses a container stack for OpenStack, focusing on the integration of OpenShift with Kubernetes for managing containerized applications on the OpenStack platform. It outlines the architecture, current state, and ideal future roadmap, highlighting the roles of various components such as orchestration, networking, and storage. The takeaway emphasizes that OpenStack facilitates resource exposure while OpenShift supports application lifecycle management, collectively enabling distributed systems operation.

OPENSTACK
Open source cloud computing
platform for building massively
scalable clouds.
Open source system for
automating deployment,
scaling and management of
containerized applications.
Provides framework for
building distributed platforms.
KUBERNETES
An integrated infrastructure
platform to run, orchestrate,
monitor and scale containers.
Built around Kubernetes and
Docker.

OPENSHIFT ON OPENSTACK
Architectural tenets:
● Technical independence
● Contextual awareness
● Avoiding redundancy
● Simplified management
?

15. A CONTAINER STACK FOR OPENSTACK - #OSSV1615
CURRENT STATE
● Orchestration and auto-scaling
via Heat templates and
Ceilometer
● Block Storage via Cinder
volumes.
● Networking via Neutron
networks.
● Load Balancing via Neutron
LBaaS
● Compute via Nova virtual
machines.

16. A CONTAINER STACK FOR OPENSTACK - #OSSV1616
IDEAL STATE (ROADMAP)
● Networking integration via
Kuryr
● Re-validate architecture on
bare-metal using Ironic
● DNS via Designate
● Load Balancing via Octavia
(LBaaS V2)
● File Storage via Manila

TAKEAWAYS
● OpenStack enables operations to expose resources
● OpenShift, built on Kubernetes, enables developers to consume resources and manage
their application life-cycle.
● OpenShift + OpenStack = Distributed Systems Operating System
