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:

       config:
         region: eu-central-1
     volumeSnapshotLocation:
       name: default
       config:

       volumeMounts:
         - mountPath: /target
           name: plugins

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>
