Migrating Rancher to New Cluster without S3
This document (000021156) is provided subject to the disclaimer at the end of this document.
Copy your backup file onto all the nodes in the new cluster. This is to ensure that the backup-operator can find the file no matter where it is scheduled.
Create a hostPath PV that mounts the directory where you copied your backup:
apiVersion: v1 kind: PersistentVolume metadata: name: migration spec: accessModes: - ReadWriteOnce capacity: storage: 10Gi hostPath: path: /migration-backup type: "" persistentVolumeReclaimPolicy: Retain volumeMode: Filesystem
Install or update the rancher-backup Helm chart on the new cluster, adding the option to use an existing PV with the following options:
--set persistence.enabled=true --set persistence.volumeName="migration"Confirm that the backup operator successfully mounted the hostPath and your backup is present
kubectl -n cattle-resources-system exec deploy/rancher-backup -- ls /var/lib/backupsCreate a Restore object
