Filesystem PVC and POD Workload

AI Tools

This chart will install the following resources:

A PVC named example-fs-pvc referencing the previously defined StorageClass.
A POD named example-fs-pod using example-fs-pvc.

Deploying the Filesystem Workload

helm install \ --set filesystem.enabled=true \ lb-csi-workload-filesystem \ lightbits-helm-repo/lb-csi-workload-examples

Will output:

NAME: lb-csi-workload-filesystem LAST DEPLOYED: Sun Feb 21 16:09:02 2021 NAMESPACE: default STATUS: deployed REVISION: 1 TEST SUITE: None

Deploying the POD on a Specific K8S Node

You can choose to deploy the POD on a specific K8s node by specifying nodeName or nodeSelector in the template.

The default values for these parameters are empty, which means the POD will not be limited to any POD.

Examples:

Specifying nodeSelector:

helm template \ --set filesystem.enabled=true \ --set filesystem.nodeSelector."beta\.kubernetes\.io/arch"=amd64,filesystem.nodeSelector.disktype=ssd \ lightbits-helm-repo/lb-csi-workload-examples

Will result in:

kind: Pod apiVersion: v1 metadata: name: example-filesystem-pod spec: nodeSelector: beta.kubernetes.io/arch: amd64 disktype: ssd containers: ...

Specifying nodeName:

helm template \ --set filesystem.enabled=true \ --set filesystem.nodeName=node00.local \ lightbits-helm-repo/lb-csi-workload-examples

Will result in:

kind: Pod apiVersion: v1 metadata: name: example-fs-pod spec: nodeName: node00.local containers: ...

Verifying the Filesystem Workload Deployed

Verify that PV, PVC are created and in Bounded state, and that POD is in Running state:

kubectl get pv,pvc,pods NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE persistentvolume/pvc-e0ad4f63-4b42-417f-8bed-94f8aec8f0d5 10Gi RWO Delete Bound default/example-fs-pvc example-sc 33s NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE persistentvolumeclaim/example-fs-pvc Bound pvc-e0ad4f63-4b42-417f-8bed-94f8aec8f0d5 10Gi RWO example-sc 34s NAME READY STATUS RESTARTS AGE pod/example-fs-pod 1/1 Running 0 34s

Uninstalling the Filesystem Workload

helm uninstall lb-csi-workload-filesystem

Verify that all resources are gone:

kubectl get pv,pvc,pods No resources found in default namespace.
