|
|
# 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
|
|
#

# ClusterRole: allows fission-executor to create/update fission-fetcher SA,
|
|
# Role and RoleBinding in any user namespace managed by NSWatcher.
|
|
#
|
|
# It also needs two less-obvious permissions:
|
|
# 1. localsubjectaccessreviews.create — setupSAAndRoleBindings checks whether
|
|
# the target SA already has each permission before creating missing rules.
|
|
# 2. events.create — Kubernetes forbids creating a Role that grants permissions
|
|
# the caller does not currently hold. Since fission-fetcher gets events.create,
|
|
# fission-executor must hold it too in order to create that Role.
