# deploy/multitenant/rbac.yaml
#
# RBAC required for the Fission multi-tenant NSWatcher.
#
# The fission-executor ServiceAccount must be allowed to list and watch Namespaces
# at the cluster scope so that NSWatcher can detect newly-labeled Namespaces.
#
# This is a read-only ClusterRole — no write permissions are granted.
# Apply once per cluster after installing Fission:
#
#   kubectl apply -f deploy/multitenant/rbac.yaml
