# Init containers are run only once in the lifetime of a pod, before
# it's started up for the first time. It has to exit successfully
# before the pod's main containers are allowed to start.
# This particular init container does a DNS lookup for other pods in
# the set to help determine whether or not a cluster already exists.
# If any other pods exist, it creates a file in the cockroach-data
# directory to pass that information along to the primary container that
# has to decide what command-line flags to use when starting CockroachDB.
# This only matters when a pod's persistent volume is empty - if it has
# data from a previous execution, that data will always be used.
#
# If your Kubernetes cluster uses a custom DNS domain, you will have
# to add an additional arg to this pod: "-domain=<your-custom-domain>"
