How do I implement RBAC for Kubernetes debugging?

Craft namespace-scoped Roles like oncall-debug for pods/log, exec, port-forward. Bind to groups via IdP, never users.

What are short-lived credentials in Kubernetes?

OIDC tokens or YubiKey-signed certs that tie sessions to your identity, expire in minutes, enforced by gateway proxies.

Teleport or StrongDM gateways; pair with cert-manager for just-in-time pods.

Picture this: 3 a.m. outage, prod's on fire, and your go-to fix is cluster-admin access. It works — until the breach report lands in your lap.
