K8s Reading-Level (Deployment/Service YAML)

# K8s Reading-Level (Deployment/Service YAML) Read and annotate a Deployment/Service pair. Writing manifests from scratch is out of scope; recognizing what each field does is the bar. ## 1. Deployment (reading map) `replicas`, image tag (pinned, never `latest`), env from secrets, resource `requests/limits`, `readinessProbe` (gates traffic) vs `livenessProbe` (restarts). Annotate each field in one line: what breaks if it is wrong. ## 2. Service (reading map) Selector matching the Deployment labels, port mapping, `ClusterIP` vs `LoadBalancer`. Annotate: what the caller hits and what breaks on mismatch. ## 3. GCP parity note Same reading skill transfers to Cloud Run service YAML (concurrency, min/max instances). Field names differ; the questions to ask of each field do not.
