Docker and CI/CD · Middle · Question 31 of 75

Does Kubernetes use the Dockerfile `HEALTHCHECK`?

1Yes, it restarts pods when the healthcheck fails
✓Correct answer: No, it uses its own liveness and readiness probes
3Yes, but only for images built with BuildKit

Explanation

Kubernetes ignores the image healthcheck. Define probes in the pod spec so it knows when to route traffic and when to restart.
