Deploying Block PVC and POD

This chart will install the following resources:

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

Deploying the Block Workload

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

Will output:

Bash
    
 
NAME: lb-csi-workload-blockLAST DEPLOYED: Sun Feb 21 16:09:02 2021NAMESPACE: defaultSTATUS: deployedREVISION: 1TEST SUITE: None
Copy

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:

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

Will result in:

Bash
    
 
kind: PodapiVersion: v1metadata:name: example-block-podspec:nodeSelector:beta.kubernetes.io/arch: amd64disktype: ssdcontainers:...
Copy

Specifying nodeName:

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

Will result in:

Bash
    
 
kind: PodapiVersion: v1metadata:name: example-block-podspec:nodeName: node00.localcontainers:...
Copy

Verifying the Block Workload
