# The CONFIG REWRITE command rewrites the redis.conf

# Because of above behaviour it's needed to
# hack kolla's CMD.

# Without this hack
# /usr/local/bin/kolla_set_configs --check
# is always reporting changed.
#
# Therefore redis-sentinel is always restarted
# even if configuration is not changed from
# kolla-ansible side.
