NetBackup™ Deployment Guide for Kubernetes Clusters

Prerequisites to deploy operators

Ensure that the following steps are performed before deploying the operators:

1. Install cert-manager by using the following command:

   helm repo add jetstack https://charts.jetstack.io --force-update

   helm upgrade -i -n cert-manager cert-manager jetstack/cert-manager \ --version 1.13.3 \ --set webhook.timeoutSeconds=30 \ --set installCRDs=true \ --wait --create-namespace

   For details, see cert-manager Documentation.

2. Create NetBackup namespace by using the following command:

   kubectl create ns netbackup

3. Install trust-manager by using the following command:

   kubectl create namespace trust-manager

   helm upgrade -i --create-namespace --namespace trust-manager trust-manager jetstack/trust-manager --set app.trust.namespace=netbackup --version v0.7.0 --wait

   For details, see trust-manager Documentation.

To deploy the operators

1. Use the following command to save the operators chart values to a file:

   helm show values operators-10.5.x.x.xxxx.tgz > operators-values.yaml

2. Use the following command to edit the chart values to fit your requirement:

   vi operators-values.yaml

3. Execute the following command to deploy the operators:

   helm upgrade --install operators operators-10.5.x.x.xxxx.tgz -f operators-values.yaml --create-namespace --namespace netbackup-operator-system

   Or

   If using the OCI container registry, use the following command:

   helm upgrade --install operators oci://abcd.veritas.com:5000/helm-charts/operators --version 10.5.x.x.xxxx -f operators-values.yaml --create-namespace --namespace netbackup-operator-system

   Following is the output of the above command:

   $ helm show values operators-10.5.x.x.xxxx.tgz > operators-values.yaml
   $
   $ vi operators-values.yaml
   $
   $ helm upgrade --install operators operators-10.5.x.x.xxxx.tgz \
   >         -f operators-values.yaml \
   >         --create-namespace \
   >         --namespace netbackup-operator-system
