policy-create-helm-backup-triliovault-for-kubernetes.yaml

# This policy creates a helm release based backup using Triliovault for Kubernetes (TVK)
# on all clusters with a label "protected-by=triliovault".
#
# To create helm based application 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:
#      Application to be backed up selected by specified helm release
#      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,
#    backup namespace and the helm release.
