Looking for a way to deploy a stable OpenStack Cloud Environment with Opendaylight at ease? This session is about learning to deploy a Cloud environment with OPNFV Fuel deployer. Fuel is a deployment tool which deploys a wide variety of distributions with third party plugins like OpenDayLight, while abstracting out complexities of the deployment. The intent of this session is to familiarize deployment of OpenStack with OpenDaylight. About the presenter: Pramod Raghavendra Jayathirth is a software developer in OpenStack and OpenDayLight, working for OTC, SSG at Intel. His Area of Interest is in Cloud Networking and Applications. He has prior experience in Databases and his current focus is on developing features of Cloud Networking Platform. He holds Masters Degree from San Jose State University.

5. Kubernetes 101
 Master components
 API Server – Frontend for K8S control plane
 Scheduler
 Control-manager
 Node Controller
 Replication Controller
 Endpoints Controller
 Service account and token controllers
 Etcd – All clustered data is stored
 Worker Node
 Kubelet - primary node agent and watches pod that has been
assigned to node
 Kube-proxy – enables service abstraction by maintaining
network rules on the host

6. Kubernetes components
 Abstraction
 Service – defines logical set of Pods
 Replication Controller – Defines pod count that corresponds to Service
 POD – Encompasses the containers the pods that are related/microservice

7. Kubernetes Networking - Overview
 CNI uses CNI Network plugin to setup
container networking
(If container runtime is docker, CNM will not
be used)
 Plugin responsible for creating network
interface to container
 Plugin calls IPAM to setup IP address
 Plugin needs to implement API for
network creation and deletion

8. Openstack Kuryr 101
• Controller
• Watches K8S API endpoints
to make sure that the
corresponding model is
maintained in Neutron
• Updates K8S resource
endpoints annotations to
keep neutron details
required by CNI driver
• Watcher
• Used by both Controller
and CNI Driver
• Connects to K8S API
• Observe Registered
Endpoints and invoke
call back handlers
• CNI Driver
