policy-continuous-restore-triliovault-for-kubernetes.yaml

# This is the 3rd policy to setup Continuous Restore Functionality using
# Triliovault for Kubernetes (TVK).
#
# This policy recovers the application backed up from the source cluster 
# to the target cluster participating in the Continuous Restore Functionality.
# The target cluster i defined with labels "protected-by=triliovault" and
# "tvk-continuous-restore-cluster=target"
#
# Please note TVK should be installed and configured on this cluster and the event
# target created using policy
# ./CM-Configuration-Management/policy-continuous-restore-event-target-triliovault-for-kubernetes.yaml
# before applying this policy.
#
# Also, this policy retrieves the consistent set created based on the backup 
# created using below policy 
#  ./CM-Configuration-Management/policy-continuous-restore-backup-triliovault-for-kubernetes.yaml
#
# Refer - https://docs.trilio.io/kubernetes/management-console/index/continuous-restore - Restore
#
# To create the restore, following process is followed
# 1. Create a restore CR that references the following:
#      Namespace for restore
#      Consistent Set - created from successful backup on source cluster
# 2. Apply the restore CR
#
# IMPORTANT: Please follow below instructions for the policy to work
# 1. On the hub cluster, create a configmap tvk-cr-restore-configmap in the namespace
#    where this policy is placed. The configmap has the name of the namespace
#    for the restore on the target cluster.
#
# 2. ConfigMap Example yaml (replace the values)
# apiVersion: v1
# kind: ConfigMap
# metadata:
#   name: tvk-cr-restore-configmap
# Data:
#   restoreNS: "PROVIDE_NAMESPACE"
