DevOps Interview Questions: Kubernetes & CI/CD (April 2026)

DevOps interview preparation with cloud infrastructure

Kubernetes topics that come up

Pods, deployments, services, ingress, config maps, secrets, probes, resource limits, and rollout strategies. Be ready to sketch a cluster boundary and where CI fits.

CI/CD angles

Pipeline stages, artifact promotion, canaries, and rollback. Tie answers to incidents you’ve handled or simulated.

Observability

Metrics vs logs vs traces. Alert fatigue and SLO thinking—how you’d page on user-visible errors.

Security and access

RBAC basics, least privilege, image scanning at a high level.

Practical prep

Run minikube or a managed trial. Break things on purpose—failed deploys teach faster than slides.

FAQ

Is CKA required?

Useful for some employers, not universal. Hands-on beats certificates if time is tight.

How deep on networking?

Understand DNS, TLS termination at ingress, and service discovery—deep packet analysis is rarely required.
