Storage is a critical part of running containers, and Kubernetes offers some powerful primitives for managing it. This webinar discusses various strategies for adding persistence to the containerised workloads.

2. Announcing
The Kubernetes Webinar Series
● Monthly webinar focused on helping you get started with Kubernetes
● Delivered by the experts from the container ecosystem
● Each webinar introduces a concept to accelerate your learning
● No specific prerequisites
○ Basic understanding of Docker will help
● All attendees will get $100 Google Cloud Platform Credits
● The recording of this webinar will be available at Kube.live

3. Objectives
● Adding persistence to Pods
● Dealing with block storage in the cloud
● Understanding Persistent Volumes and Claims
● Demos

4. Persistence in Pods
● Pods are ephemeral and stateless
● Volumes bring persistence to Pods
● Kubernetes volumes are similar to Docker volumes, but managed
differently
● All containers in a Pod can access the volume
● Volumes are associated with the lifecycle of Pod
● Directories in the host are exposed as volumes
● Volumes may be based on a variety of storage backends

5. Pods and Volumes

6. Kubernetes Volume Types
● Host-based
○ EmptyDir
○ HostPath
● Block Storage
○ Amazon EBS
○ GCE Persistent Disk
○ Azure Disk
○ vSphere Volume
○ ...
● Distributed File System
○ NFS
○ Ceph
○ Gluster
○ Amazon EFS
○ Azure File System
○ ...
● Other
○ Flocker
○ iScsi
○ Git Repo
○ Quobyte
○ ...

Block Storage-based Volumes

9. Understanding Persistent Volumes & Claims
● PersistentVolume (PV)
○ Networked storage in the cluster pre-provisioned by an administrator.
● PersistentVolumeClaim (PVC)
○ Storage resource requested by a user.
● StorageClass
○ Types of supported storage profiles offered by administrators

10. Storage Provisioning Workflow
Lifecycle of a Persistent Volume
● Provisioning
● Binding
● Using
● Releasing
● Reclaiming

Volumes

12. Upcoming Webinar
Configuring & Deploying StatefulSets
9AM PST, Tuesday, Feb. 14th
StatefulSets bring the flexibility and availability of ReplicaSets to stateful
workloads such as NoSQL databases and RDBMS. In this webinar, we
will configure a highly available cluster of MySQL in Kubernetes based
on the concept of StatefulSet. We will also cover the concepts of node
affinity and horizontal pod autoscaling to achieve scalability, reliability,
and availability of a web-scale deployment.
