A Practical Guide to Kubernetes

Creating StorageClasses

Explore how to create and manage Kubernetes StorageClasses to support persistent storage for stateful applications. Understand the process from creating a StorageClass, deploying applications with PersistentVolumeClaims, to verifying dynamic provisioning of AWS EBS volumes in your cluster under the fast StorageClass configuration.

We'll cover the following...

Creating the class

Let’s create our StorageClass:

Shell
kubectl create -f pv/sc.yml

The output shows that the storageclass "fast" was created.

Verification

Let’s list the StorageClasses in our cluster.

Shell
kubectl get sc

The output is as follows:

Shell
NAME          PROVISIONER           AGE
default       kubernetes.io/aws-ebs 58m
fast          kubernetes.io/aws-ebs 19s
gp2 (default) kubernetes.io/aws-ebs 58m

We can see that, this time, we have a new StorageClass.

Creating the Deployment

Let’s look at yet another Jenkins definition:

Shell
cat pv/jenkins-sc.yml

The output (limited to ...
