Portworx Kubernetes Snapshots Practice Lab

Lab Information

We have created a few Deployment/StatefulSets for you to explore.

Inspect existing deployments

How many deployments have been created for MYSQL with label `app=mysql` in this cluster (all namespaces)?

How many PVCs have been created for MYSQL?

What is the name of the storage class used to create this PVC?

What is the `io_profile` used for this storage class?

Create a new volume snapshot

Q5: Create a snapshot called `mysql-snap` for the PVC `px-mysql-pvc`.

Run the below command to create the snapshot:

Restore snapshot to same PVC

Restore the snapshot to the same PVC `px-mysql-pvc` in the same Namespace as the source. Call the restore object as `mysql-snap-restore`

Run the below command to create the snapshot:

Inspect existing StatefulSets

We have created a new StatefulSet for you to explore.

Create a group volume snapshot

Q5: Create a group snapshot called `nginx-group-snap` for the PVC's of the nginx StatefulSet. Make sure that the snapshot can be restored to a new namespace called `nginx-clone`.

Run the below command to create the snapshot:

Clone snapshots to new PVC's

Restore the snapshot taken for the pod `web-0` to a new PVC `web-clone-0` in the `default` namespace.

Use the below template to create a clone from the volumesnapshot for PVC of 'pod - 0' of the nginx StatefulSet::
