Script to annotate a pod with a Velero Restic volume list

annotate-pod.sh

#!/bin/bash
# This script adds Velero/Restic labels to a pod according to the pod's
#   current volume set (filtering to only persistentVolumeClaims)
#   According to https://heptio.github.io/velero/v0.11.0/restic
# TODO: Make this script produce help if options are not given
#       Currently it just assumes you mean to annotate a NooBaa server pod
#       Usage:
#           annotate-pod.sh namespace pod
#
NS=${1:-noobaa}
POD=${2:-noobaa-server-0}
JQUERY="-o=jsonpath={.spec.volumes[?(@.persistentVolumeClaim)].name}"

PVS=$(oc -n ${NS} get pod ${POD} ${JQUERY} | tr ' ' ,)

oc -n ${NS} annotate pod/${POD} backup.velero.io/backup-volumes=${PVS}
