Steps

Define readinessProbe (gates traffic) and livenessProbe (restarts) separately, with realistic initialDelaySeconds
Set strategy rollingUpdate maxUnavailable=0, maxSurge=1 for no capacity dip
Handle SIGTERM in the app: stop accepting work, drain, exit before terminationGracePeriodSeconds
kubectl rollout status deployment/x to gate the pipeline; rollout undo on failure

Known gotchas

No readinessProbe = traffic hits pods before the app boots — the classic 502 burst on every deploy
preStop sleep (5-10s) is still needed because endpoint removal and SIGTERM race each other
Liveness probe that checks dependencies (DB) causes restart storms during dependency blips — keep liveness dumb, readiness smart
