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
   

   Note

   On an OpenShift cluster, run the oc command instead of kubectl one.

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.6.5.0:

     helm install velero vmware-tanzu/velero \
     --version 6.5.0 \
     --values values.yaml \
     --namespace velero
   

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

   View: values.yaml

   securityContext:
     fsGroup: 65534
   restic:
     securityContext:
       fsGroup: 65534
   serviceAccount:
     server:
       create: true
       name: edp-velero
       annotations:
         eks.amazonaws.com/role-arn: "arn:aws:iam::<AWS_ACCOUNT_ID>:role/AWSIRSA‹CLUSTER_NAME›‹VELERO_NAMESPACE›Velero"
   credentials:
     useSecret: false
   configuration:
     backupStorageLocation:
     - name: default
       provider: aws
       bucket: velero-<CLUSTER_NAME>
       config:
         region: eu-central-1
     volumeSnapshotLocation:
     - name: default
       provider: aws
       config:
         region: <AWS_REGION>
   initContainers:
     - name: velero-plugin-for-aws
       image: velero/velero-plugin-for-aws:v1.9.2
       volumeMounts:
         - mountPath: /target
           name: plugins
   

   Note

   In case of using cluster scheduling and amazon-eks-pod-identity-webhook, it is necessary to restart the Velero pod after the cluster is up and running. Please refer to the Schedule Pods Restart documentation.

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>
