# This policy creates a namespace based backup using Triliovault for Kubernetes (TVK)
# on all OpenShift managed clusters with a label "protected-by=triliovault".
#
# This policy creates backup for all the namespaces with a lable "protected-by=tvk-ns-backup"
#
# 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
# On the hub cluster, create a secret aws-s3-secret and a configmap aws-s3-configmap
# in the namespace where this policy is placed. The secret and configmap have AWS S3
# details for target creation.
#
# 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"
