Liveness vs Readiness Probes

Liveness restarts a broken pod; readiness removes it from the Service. Confusing the two is the #1 cause of self-inflicted outages during deploys.

Requests, Limits & QoS Classes

Requests drive scheduling and QoS class; limits drive throttling and OOMKill. Memory limits without matching JVM heap settings = surprise restarts.

Observability: Logs, Metrics, Traces

Metrics for what, logs for why, traces for where. Cardinality kills your bill — design label schemas like you design DB schemas.

Designing a CI/CD Pipeline

Ingress is the legacy API; Gateway API is its principled replacement. Reach for a service mesh only when you need mTLS, traffic shifting, or per-service policy.
