1. NETAPP NETAPP KUBERNETES KUBERNETES SERVICES SERVICES Adrian Kosmaczewski
2. AGENDA AGENDA 1. Introduction to Kubernetes 2. Demo of the NetApp Kubernetes Service 3. Introduction to OpenShift
3. KUBERNETES KUBERNETES Feature-rich, established and growing True cloud platform Horizontal scaling Automated rollouts and rollbacks Self-healing
4. KUBERNETES KUBERNETES Third generation container management from Google Open sourced in 2014 Rapid adoption in market Strong contributors like Red Hat (OpenShift)
5. KUBERNETES KUBERNETES Available on Amazon: EKS Google Cloud Platform: GKE Azure: AKS Your laptop!
6. KUBERNETES TERMINOLOGY KUBERNETES TERMINOLOGY Pod Pod One or more containers running inside Kubernetes Service Service Publicly-available endpoint to access a web service through a load balancer
7. KUBERNETES TERMINOLOGY KUBERNETES TERMINOLOGY Persistence Volume (PV) Persistence Volume (PV) Unit of networked storage Persistence Volume Claim (PVC) Persistence Volume Claim (PVC) Request for storage from a Pod
8. TRIDENT TRIDENT Storage orchestrator for NetApp storage Open Source (released December 2016) Out of tree, out of process Usually installed as a Kubernetes pod Watches for PVC requests
9. REVOLUTION REVOLUTION Containers have taken over Kubernetes is leader in container orchestration Trident enables dynamically provisioned storage for Kubernetes NetApp Kubernetes Service makes Kubernetes easier!
