Set resource requests and limits

Without them the scheduler guesses and noisy neighbours starve you.

$resources: requests: { cpu: 100m, memory: 128Mi } limits: { cpu: 500m, memory: 512Mi }

Add liveness and readiness probes

Readiness gates traffic; liveness restarts a wedged pod.

Define a PodDisruptionBudget

Keeps a minimum of replicas during node drains.

Pin the image by digest, not :latest

Set rollingUpdate maxUnavailable/maxSurge

$strategy: { rollingUpdate: { maxUnavailable: 0, maxSurge: 1 } }

Wire a HorizontalPodAutoscaler if load varies
