Kubernetes RBAC reference: the Role and ClusterRole binding model, evaluation logic, escalation paths, least-privilege patterns for developers, CI/CD, monitoring, and break-glass access, plus common misconfigurations. Use when writing RBAC manifests or reviewing who can do what in a cluster.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# K8s RBAC Patterns > RBAC design patterns, least-privilege role definitions, common misconfigurations, and privilege escalation prevention. ## Knowledge Base ### RBAC Object Model Kubernetes RBAC uses four object types: | Object | Scope | Purpose | |--------|-------|---------| | **Role** | Namespace | Defines permissions within a single namespace | | **ClusterRole** | Cluster-wide | Defines permissions across all namespaces or for cluster-scoped resources | | **RoleBinding** | Namespace | Binds a Role OR ClusterRole to subjects within a namespace | | **ClusterRoleBinding** | Cluster-wide | Binds a ClusterRole to subjects across all namespaces | **Critical distinction**: A ClusterRole bound with a RoleBinding is scoped to that namespace. The same ClusterRole bound with a ClusterRoleBinding applies cluster-wide. This is how you create reusable role definitions with namespace-scoped grants. ### RBAC Evaluation Logic 1. All RBAC rules are **additive** -- there is no deny rule in Kubernetes RBAC 2. If no rule grants access, the request is **denied by default** 3. Rules are evaluated by the API server at request time …

How to install
mdr add hermeticormus/libresecops-claude-code/k8s-rbac-patterns@sha256:d6f9470f4aa7c954The line at the top of this page pins the label git:20260930.71a2663, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
