Run this in order to backup all you k8s cluster data. It will be saved in a folder bkp. To restore the cluster, you can run kubectl apply -f ${BACKUP_OUTPUT_DIR}.

Please note: this recovers all resources correctly, including dynamically generated PV's. However, it will not recover ELB endpoints. You will need to update any DNS entries manually, and manually remove the old ELB's.

Please note: This has not been tested with all resource types. Supported resource types include:

• services
• replicationcontrollers
• secrets
• deployments
• horizontal pod autoscalers
