#
#
# The addition below can be executed after the invocation of
# the original service_delivery_controller_opnfv.yaml
# by invoking:
# % kubectl create -f <(istioctl kube-inject --debug -f cassandra.yaml)
#
#
#
# Cassandra Statefulset
#
# Assumption:
# - The Cassandra Statefulset right now assumes that
# the service is deployed in the 'default' namespace
# therefore the environment variable CASSANDRA_SEEDS is set to
# "cassandra-0.cassandra.default.svc.cluster.local" below.
# if you want to use your own name space other than 'default'
# the value becomes:
# "cassandra-0.cassandra.<NAMESPACE_NAME>.svc.cluster.local"
# note that this value rely on a functioning DNS on kubernetes to resolve the IP
#
# This static method can be made dynamic by using Helm
# or bash script to replace the namespace on the fly.
#
# - Cassandra launch only 1 replica in the cluster
# to dynamically scale up or down, you can use:
# kubectl edit statefulset cassandra
# and edit the value of the replica key
#
#
