You can use Velero to back up the kubernetes resources including persistent volumes data under specific namespaces.

Prerequisites

Install and Configure Velero Add-On for the Workload Clusters.

Procedure

  1. Log in to the VMware Telco Cloud Automation web interface.
  2. Navigate to Infrastructure > Virtual Infrastructure.
  3. Open the web terminal by clicking the Options (three dots) corresponding to the workload cluster you want to backup and then selecting Open Terminal.
  4. On the Web terminal, check the service health of Velero by running the following command: 
    # kubectl get pod -n velero
# kubectl get bsl -n velero
  5. Set an environmental variable to exclude the cluster resources from backing up. 
    # export TCA_VELERO_EXCLUDE_RESOURCES="issuers.cert-manager.io,certificates.cert-manager.io,certificaterequests.cert-manager.io,gateways.networking.x-k8s.io,gatewayclasses.networking.x-k8s.io"
  6. Back up specific namespaces. 
    # velero backup create <example-backup> --exclude-resources $TCA_VELERO_EXCLUDE_RESOURCES --include-namespaces <example-namespaces-by-comma> 
  7. Check backup status and upload CR and wait until the processes are"Completed". 
    # velero backup get // check the backup status
# kubectl get uploads -n velero // get the upload-name 
# kubectl get uploads <upload-name> -o yaml // check the uploads status in yaml output
