# Read-only identity for the cluster-inspector agent.
|
|
# Apply to the management cluster and to every workload cluster the agent should inspect
|
|
# (CAPI rules are simply unused on workload clusters).
|
|
# Built-in `view` excludes Secrets; capi-readonly adds read access to CAPI CRDs and pod logs.
|
|
# Tokens are short-lived TokenRequest tokens minted by make-kubeconfig.sh — no Secret-based token.
