The CrashLoopBackOff Trifecta
A pod is CrashLoopBackOff-ing for three different reasons stacked on top of each other. Fix all of them and get it Running.
Puzzle Overview
A Kubernetes deployment in the `checkout` namespace is in CrashLoopBackOff. On investigation, it's not one problem but three: a malformed ConfigMap, a missing Secret, and an RBAC rule too restrictive for the pod's ServiceAccount to read its own config.
Each symptom unlocks the next. You'll need to read pod logs, describe pods, inspect events, and understand how ConfigMaps, Secrets, ServiceAccounts, Roles, and RoleBindings fit together.
