# This policy creates a namespace based backup using Triliovault for Kubernetes (TVK)
# on all OpenShift managed clusters with a label "protected-by=triliovault".
#
# To create the namespace backup, following process is followed
# 1. Create the target object to store backup data
#    This policy creates AWS S3 based target storage for storing backup images. 
# 2. Create a backup plan that references the following:
#      Namespace to be backed up 
#      Default Scheduling Policy - create daily 1 backup
#      Target to where the data should be backed up
# 3. Apply the Backup CR that references the Backup
#    This policy creates a full backup.
#
# IMPORTANT: Please follow below instructions for the policy to work
# 1. On the hub cluster, create a secret aws-s3-secret in the namespace where
#    this policy is placed. The secret has AWS S3 credentials for target creation.
# 2. On the hub cluster, create a configmap aws-s3-configmap in the namespace
#    where this policy is placed. The configmap has AWS S3 details for target creation,
#    and name of the namespace for creating namespace based backup.
#
# 1. Secret Example yaml (replace the values)
# apiVersion: v1
# kind: Secret
# metadata:
#   name: aws-s3-secret
# type: Opaque
# stringData:
#   accessKey: "PROVIDE_ACCESS_KEY"
#   secretKey: "PROVIDE_SECRET_KEY"
#
# 2. ConfigMap Example yaml (replace the values)
# apiVersion: v1
# kind: ConfigMap
# metadata:
#   name: aws-s3-configmap
# Data:
#   bucketName: "PROVIDE_S3_BUCKET_NAME"
#   region: "PROVIDE_REGION"
#   thresholdCapacity: "100Gi"
#   backupNS: "PROVIDE_NAMESPACE"
