Install Velero

Velero is an open source tool to safely back up, recover, and migrate Kubernetes clusters and persistent volumes. It works both on premises and in a public cloud. Velero consists of a server process running as a deployment in your Kubernetes cluster and a command-line interface (CLI) with which DevOps teams and platform operators configure scheduled backups, trigger ad-hoc backups, perform restores, and more.

Installation​

To install Velero, follow the steps below:

  1. Create velero namespace:

    kubectl create namespace velero

  2. Add a chart repository:

    helm repo add vmware-tanzu https://vmware-tanzu.github.io/helm-charts
    helm repo update
    note

    Velero AWS Plugin requires access to AWS resources. To configure access, please refer to the IRSA for Velero documentation.

  3. Install Velero v.2.14.13:

    helm install velero vmware-tanzu/velero \
      --version 2.14.13 \
      --values values.yaml \
      --namespace velero

    Check out the values.yaml file sample of the Velero customization:

  4. Install the client side (velero cli) according to the official documentation.

Configuration​

  1. Create backup for all components in the namespace:

    velero backup create <BACKUP_NAME> --include-namespaces <NAMESPACE>

  2. Create a daily backup of the namespace:

    velero schedule create <BACKUP_NAME>  --schedule "0 10 * * MON-FRI" --include-namespaces <NAMESPACE> --ttl 120h0m0s

  3. To restore from backup, use the following command:

    velero restore create <RESTORE_NAME> --from-backup <BACKUP_NAME>
