Node.js · Senior · Question 58 of 75

Running Node.js in Kubernetes, should you use the `cluster` module inside each pod?

1Kubernetes requires cluster for health checks
✓Correct answer: Usually not: run one process per pod and scale pods, so the orchestrator handles restarts, balancing and resource limits
3Yes, always, or Node.js uses only 10% of a core

Explanation

One process per container keeps metrics, memory limits and restarts simple. cluster still helps on a single VM without an orchestrator.
