1. What is Kubernetes?
Why you might get asked this:
Interviewers open with this baseline question to ensure you grasp the platform you will troubleshoot. A clear definition proves foundational knowledge, sets context for later, deeper basic kubernetes troubleshooting interview questions and answers, and lets them assess how well you can simplify technical concepts for non-experts. They also gauge whether you emphasize orchestration, scalability, and declarative management—core themes that drive most troubleshooting scenarios.
How to answer:
Start by framing Kubernetes as an open-source container orchestration platform that automates deployment, scaling, and operations of containerized workloads. Highlight its key primitives—Pods, Nodes, Services, and Controllers—and mention its self-healing and declarative nature. Tie back to troubleshooting: knowing these primitives helps pinpoint root causes quickly. Keep it concise but cover enough breadth to signal deep familiarity.
Example answer:
Sure. Kubernetes is an open-source orchestration system that takes container images, groups them into pods, schedules those pods across worker nodes, and continually reconciles the desired state you declare in manifests with the actual state it observes in the cluster. In practice, that means if a pod crashes or a node dies, Kubernetes automatically replaces it. My daily work involves writing manifests for microservices, then using kubectl and monitoring tools to ensure the cluster’s controllers are achieving the desired state. Because I understand how the API server, scheduler, and kubelet interact, I can quickly narrow issues—whether it is an unhealthy node or a mis-configured probe—making basic kubernetes troubleshooting interview questions and answers second nature.
2. How do you check the status of all pods?
Why you might get asked this:
A rapid status check is often the first step when an alert fires. Interviewers want to validate that you reach for the right commands instinctively and can interpret states like Running, Pending, or CrashLoopBackOff. This demonstrates fluency with basic kubernetes troubleshooting interview questions and answers and showcases your ability to triage failures efficiently.
How to answer:
Explain that the primary command is kubectl get pods, optionally with namespaced or label-based filters. Emphasize reading the STATUS column and additional flags such as --all-namespaces for cluster-wide views. Note that combining it with wide output helps spot problematic nodes. Finish by mentioning follow-up actions like kubectl describe or kubectl logs based on what you find.
Example answer:
When an incident ticket lands, my first stop is kubectl get pods --all-namespaces because it gives me a bird’s-eye view of every pod and its current lifecycle phase. If I see Pending, I note which node field is empty; if I see CrashLoopBackOff, I mark it for log review. I often add the -o wide flag so I can see which node each problematic pod sits on, which speeds correlation with node-level alerts. This simple habit, ingrained from practicing basic kubernetes troubleshooting interview questions and answers, cuts my mean-time-to-identify in half compared to hunting through dashboards first.
3. How do you view logs from a pod?
Why you might get asked this:
Logs are the single richest data source during triage. Interviewers need assurance that you know how to retrieve runtime logs and historical logs (using --previous) for crashed containers. It also signals comfort with multi-container pods and streaming outputs—topics central to basic kubernetes troubleshooting interview questions and answers.
How to answer:
State that kubectl logs shows standard output from the primary container, while kubectl logs -c targets a specific sidecar. Mention --previous to capture logs from the prior instance in CrashLoop scenarios. Describe tailing with --follow and storing outputs for deeper analysis. Conclude by linking logs to application-level debugging.
Example answer:
Once I isolate a failing pod, I run kubectl logs payment-api-1234-abcd --previous so I can see the stack trace from the last terminated container; nine times out of ten that’s enough to pinpoint the null pointer or misread config. If the pod hosts multiple containers—say, an envoy sidecar plus the app—I add -c envoy to confirm the proxy isn’t the culprit. For long-running debug, I’ll tail with --follow and pipe the output into grep to watch for repeating errors. These log routines, drilled through countless basic kubernetes troubleshooting interview questions and answers, let me diagnose issues even before metrics dashboards update.
4. How do you describe a pod to get detailed information?
Why you might get asked this:
kubectl describe is a goldmine: resource requests, mounted volumes, probe settings, event history. Interviewers expect you to mine this detail quickly and translate it into root-cause insight. The question checks your familiarity with pod anatomy and with reading Events at the bottom—essential for basic kubernetes troubleshooting interview questions and answers.
How to answer:
Explain that kubectl describe pod delivers metadata, spec, and current status sections. Emphasize scanning for container state transitions, restart counts, and Events like FailedScheduling. Point out that you can use --namespace to target specific environments and cut noise. Finally, mention how Events guide follow-up actions—adding tolerations, adjusting images, or increasing resources.
Example answer:
I treat kubectl describe like a forensic report. When the cart-service pod hit a CrashLoopBackOff last week, describe showed 7 restarts, an OOMKilled reason, and an event where the liveness probe failed. That told me memory limits were too tight, so I bumped limits in the Helm chart and redeployed. I also noticed the image pull policy was IfNotPresent, which can hide updates, so I switched to Always. Those granular insights—visible only through describe—are why mastering basic kubernetes troubleshooting interview questions and answers is so valuable for real-time triage.
5. How do you check resource utilization for pods?
Why you might get asked this:
Seeing CPU throttling or memory saturation early prevents cascading outages. Interviewers test whether you know kubectl top and metrics-server dependencies. This builds on earlier basic kubernetes troubleshooting interview questions and answers by linking observed failures to tangible resource data.
How to answer:
Start with kubectl top pods or kubectl top pod to show real-time CPU and memory stats (assuming metrics-server is installed). Clarify that HPA relies on these metrics. Mention cross-checking with describe for limits and requests, and using Prometheus/Grafana dashboards for historical trends. Close by noting how utilization guides scaling decisions or limit adjustments.
Example answer:
In our Black Friday load test, I ran kubectl top pods | sort -k3 -r to quickly spot pods pushing 95 percent CPU. The checkout-service spiked first, confirming autoscaler thresholds were too conservative. I jumped to describe to see it requested 200m CPU but limited to 500m, clearly too low for the load profile. After raising the limit to 1 core and adjusting the HPA target, usage stabilized. I always tie these metrics back to manifest settings—a reflex honed from answering basic kubernetes troubleshooting interview questions and answers in mock interviews.
6. How do you check node health and resource utilization?
Why you might get asked this:
Many pod issues trace back to unhealthy or over-committed nodes. Interviewers need proof that you zoom out beyond the pod layer. This is a staple among basic kubernetes troubleshooting interview questions and answers because node failures ripple across deployments.
How to answer:
Discuss kubectl get nodes to see Ready status. Follow with kubectl describe node for capacity, conditions (DiskPressure, MemoryPressure), and allocated resources. Note that node-level metrics come from kubectl top nodes, Prometheus, or cloud provider dashboards. Explain correlating taints, labels, and instance size to troubleshooting decisions.
Example answer:
Last month we hit DiskPressure on an older m5.large node. kubectl get nodes showed it as NotReady,SchedulingDisabled. describe revealed 95 percent disk use in /var/lib/docker. We cleaned dangling images and added an eviction-threshold alert. In parallel, I cordoned the node so workloads shifted elsewhere. That full-stack view—from node status to pod rescheduling—is central to effective basic kubernetes troubleshooting interview questions and answers.
7. How do you troubleshoot a pod stuck in Pending state?
Why you might get asked this:
Pending pods disrupt deployments and signal scheduler or resource issues. Interviewers want to see systematic diagnosis. It is a canonical item on any list of basic kubernetes troubleshooting interview questions and answers.
How to answer:
kubectl describe pod to read Events (FailedScheduling).
Check resource requests vs. node capacity.
Inspect node taints, tolerations, affinity rules, and quotas. Finish by mentioning adjusting requests or adding capacity.
Outline a three-step flow:
Example answer:
When our ML batch job pods hung in Pending, describe showed 4Gi memory request unschedulable: no nodes had that capacity. A quick kubectl get nodes -o wide confirmed all nodes were smaller t3.medium instances. We scaled up a GPU node pool with 8Gi memory, added a nodeSelector in the pod spec, and the scheduler immediately placed the pods. Walking through those exact steps mirrors how I tackle basic kubernetes troubleshooting interview questions and answers during onboarding sessions.
8. How do you diagnose a pod in CrashLoopBackOff?
Why you might get asked this:
CrashLoopBackOff screams production outage. Interviewers test depth of log analysis, probe settings, and resource understanding—key dimensions of basic kubernetes troubleshooting interview questions and answers.
How to answer:
Start with kubectl describe for restart counts and last exit code. Then kubectl logs --previous for the failing container. Mention checking readiness/liveness probes and resource limits, as OOM kills often cause loops. Propose fixes: correct command, mount secrets, increase limits, or adjust probes.
Example answer:
Our auth-service kept CrashLoopBackOff every 45 seconds. describe showed ExitCode 1, Reason Error. logs --previous revealed missing ENV var DB_HOST. The secret volume hadn’t mounted due to a mislabeled name in the Deployment. After updating the envFrom reference and redeploying, restarts dropped to zero. Moments like these prove the value of rehearsing basic kubernetes troubleshooting interview questions and answers because they map exactly to real production saves.
9. How do you resolve a failed image pull?
Why you might get asked this:
Image pull errors halt new pod scheduling. The fix might be credentials, network, or tag mistakes. Interviewers include this in basic kubernetes troubleshooting interview questions and answers to evaluate registry knowledge and secret management.
How to answer:
Explain reading Events from describe to find ErrImagePull or ImagePullBackOff. Validate tag correctness. Check private registry credentials via imagePullSecrets. Test docker pull locally. If using ECR or GCR, confirm IAM roles or service account access. Reference network proxy rules if offline.
Example answer:
When our staging pods hit ImagePullBackOff, describe pointed to 401 Unauthorized from ECR. I inspected the service account and saw the AWS IAM role missing ecr:GetAuthorizationToken. After adding that policy and renewing the token, kubectl rollout restart deployment succeeded. Basic kubernetes troubleshooting interview questions and answers often come down to knowing where credentials live and how they expire.
10. How do you test network connectivity from a pod?
Why you might get asked this:
Networking weaves through most incidents—DNS, service mesh, firewalls. Interviewers measure your debug toolkit. This is a top item in basic kubernetes troubleshooting interview questions and answers.
How to answer:
Describe kubectl exec -it -- ping or curl to internal service names or external URLs. Note that BusyBox or alpine containers are useful. Mention using nslookup or dig for DNS. For advanced cases, reference network policies or CNI plugin logs.
Example answer:
I generally spin up a temp alpine pod kubectl run net-debug --rm -it --image=alpine and ping the service cluster-IP. In one outage, ping worked but curl failed with TLS handshake timeout, narrowing it to Istio sidecar rules. We then traced it to an outbound egress policy. Practicing such scenarios through basic kubernetes troubleshooting interview questions and answers meant the solution surfaced in minutes, not hours.
11. How do you check service endpoints?
Why you might get asked this:
Services glue pods to traffic. Mismatched labels cause silent failures. Interviewers include this check in basic kubernetes troubleshooting interview questions and answers to see if you verify selectors.
How to answer:
State kubectl get endpoints and kubectl describe service. Compare selector labels with pod labels. If endpoints list is empty, the selector is wrong or pods aren’t Ready. Link to readiness probes.
Example answer:
During a blue-green rollout, the blue service returned no endpoints. describe service blue-api showed selector app=blue-api,version=v1, but the new pods carried version=v2. Updating the deployment label fixed traffic instantly. Troubles like this are why basic kubernetes troubleshooting interview questions and answers stress label hygiene.
12. How do you expose a pod as a service?
Why you might get asked this:
You must prove you know service types and quick exposure steps, fundamental to basic kubernetes troubleshooting interview questions and answers.
How to answer:
You can create a manifest or run kubectl expose pod --type=ClusterIP --port=. Emphasize setting correct targetPort and labels. Mention other types (NodePort, LoadBalancer).
Example answer:
For ad-hoc QA testing, I often kubectl expose pod redis-test --type=ClusterIP --port=6379, then port-forward from my laptop. In production, a manifest grants version control. Knowing both quick and declarative paths is expected in basic kubernetes troubleshooting interview questions and answers.
13. How do you check for DNS issues in Kubernetes?
Why you might get asked this:
Microservices rely on DNS names. Failures break inter-pod calls. Interviewers assess cluster-DNS fluency, making it staple in basic kubernetes troubleshooting interview questions and answers.
How to answer:
Use kubectl exec into a pod, run nslookup service.namespace.svc.cluster.local. Check kube-dns or CoreDNS pod logs. Verify ConfigMap for stub domains. Mention checking network policies blocking port 53/udp.
Example answer:
Our customer-service pod couldn’t resolve db-svc. nslookup returned SERVFAIL. CoreDNS logs showed loop detected due to conflicting upstream stub. Removing the stale stub entry restored resolution. Scenarios like this reinforce the importance of practicing basic kubernetes troubleshooting interview questions and answers in a sandbox.
14. How do you scale a deployment?
Why you might get asked this:
Scaling is routine yet critical. Interviewers want command fluency—another foundational element of basic kubernetes troubleshooting interview questions and answers.
How to answer:
kubectl scale deployment --replicas=. Mention editing the manifest or autoscaler for permanence. Tie scaling to metrics.
Example answer:
During a promo launch, we jumped payment-api replicas from 5 to 20 with kubectl scale. Grafana latency charts immediately leveled off. After the event, I reverted via git-ops. Knowing when to use manual versus HPA scaling is a nuance highlighted in basic kubernetes troubleshooting interview questions and answers.
15. How do you resolve a deployment that is not scaling as expected?
Why you might get asked this:
Diagnosing HPA or deployment rollout stalls tests holistic thinking—central to basic kubernetes troubleshooting interview questions and answers.
How to answer:
Check kubectl describe deployment for conditions. Verify HPA targets, resource limits, and that metrics-server is running. Validate PodDisruptionBudget caps. Examine Events for scaling restrictions.
Example answer:
Our HPA for search-api stayed at 3 replicas despite 90 percent CPU. describe hpa showed missing metrics: unknown. metrics-server pod had RBAC errors reading node stats. Fixing the ClusterRoleBinding allowed scaling to 12 replicas. Such multi-layer problems are why interviewers lean on basic kubernetes troubleshooting interview questions and answers to reveal depth.
16. What is the role of etcd in Kubernetes?
Why you might get asked this:
Understanding etcd is vital for disaster recovery and performance. It ranks highly among basic kubernetes troubleshooting interview questions and answers.
How to answer:
Explain etcd as the distributed key-value store holding all cluster state—pods, secrets, config maps. Mention consensus, snapshots, and latency impact on API responsiveness. Note securing with TLS.
Example answer:
I view etcd as Kubernetes’ source of truth. When we hit API latency spikes, etcd metrics showed high disk I/O wait. Compaction hadn’t run, so we scheduled regular defrags and enabled SSD volumes. Recognizing etcd’s footprint helped restore API throughput—knowledge sharpened by studying basic kubernetes troubleshooting interview questions and answers.
17. How do you troubleshoot a pod that is running but not reachable from a service?
Why you might get asked this:
This tests label matching, readiness probes, and networking. It’s a frequent flier in basic kubernetes troubleshooting interview questions and answers.
How to answer:
First get endpoints; if empty, mismatch labels or pod not Ready. Check selector, pod labels, and readiness status. Confirm service port and targetPort align. Inspect network policies.
Example answer:
Our frontend-svc returned 503s even though pods were Running. get endpoints showed none. describe pod unveiled readiness probe failing on /healthz. The container listened on 8081, but probe pointed at 8080. Fixing the probe made endpoints populate and traffic flow. This is classic among basic kubernetes troubleshooting interview questions and answers.
18. What are taints and tolerations?
Why you might get asked this:
They are advanced scheduling controls. Interviewers gauge how you isolate workloads—integral to basic kubernetes troubleshooting interview questions and answers.
How to answer:
Taints repel pods from nodes unless a pod has matching toleration. Use them for GPU nodes or dedicated workloads. Describe the key, value, effect trio and tolerationSeconds for temporary placement.
Example answer:
We run GPU nodes tainted with gpu=true:NoSchedule. Only ML pods have toleration key gpu=true. When a non-ML pod stuck in Pending, describe revealed unschedulable due to that taint. Removing the nodeSelector fixed placement. These subtle scheduling rules appear often in basic kubernetes troubleshooting interview questions and answers.
19. How do you monitor a Kubernetes cluster?
Why you might get asked this:
Proactive health beats reactive fixes. Interviewers ask this in the suite of basic kubernetes troubleshooting interview questions and answers to see your observability stack.
How to answer:
Mention Prometheus, Grafana, Alertmanager, metrics-server, kube-state-metrics, and logging stacks like EFK. Discuss proactive alert thresholds and dashboards.
Example answer:
Our stack: Prometheus scrapes kubelet, cAdvisor, and app metrics, feeding Grafana dashboards. Alertmanager pages on 5-minute p99 latency or >3 percent pod restarts. Central logs in Elasticsearch let us correlate errors. Building this observability fabric is part of mastering basic kubernetes troubleshooting interview questions and answers.
20. How do you collect logs from multiple pods?
Why you might get asked this:
Efficiently aggregating logs signals scalability thinking. This appears in basic kubernetes troubleshooting interview questions and answers.
How to answer:
Use kubectl logs -l app= or deploy centralized logging: Fluent Bit, Logstash, or Loki. Explain label selectors and multi-container considerations.
Example answer:
During a payment outage, I ran kubectl logs -l app=payment -c app --since=5m to sweep all replicas instantly. For long-term search, we forward logs via Fluent Bit to Loki, so a single query pulls every pod’s trace. These techniques come straight from practicing basic kubernetes troubleshooting interview questions and answers.
21. How do you restart a pod?
Why you might get asked this:
Sometimes a quick restart resolves transient issues. Interviewers include it in basic kubernetes troubleshooting interview questions and answers to test controller understanding.
How to answer:
Delete pod; the ReplicaSet or Deployment recreates it. Alternatively patch deployment annotation to trigger rollout. Emphasize not editing running manifests manually.
Example answer:
If cart-service misbehaves, kubectl delete pod cart-svc-abcd; within seconds the ReplicaSet spins up a fresh pod. For bulk restart, kubectl rollout restart deployment/cart-service updates its template hash. These methods, reinforced through basic kubernetes troubleshooting interview questions and answers, ensure uptime while refreshing state.
22. How do you check cluster events?
Why you might get asked this:
Events narrate recent failures. Interpreting them is core to basic kubernetes troubleshooting interview questions and answers.
How to answer:
kubectl get events --sort-by=.metadata.creationTimestamp or watch kubectl get events. Mention filtering by namespace and interpreting common reasons.
Example answer:
When a deployment stalled, events showed FailedMount for a secret. That pointed directly to a typo in the volume name. Keeping a watch command open during rollouts is a tip I share in workshops on basic kubernetes troubleshooting interview questions and answers.
23. How do you debug a slow application in Kubernetes?
Why you might get asked this:
Performance issues mix resources, networking, and code. Interviewers test integrated thinking through basic kubernetes troubleshooting interview questions and answers.
How to answer:
Check pod metrics (top), node health, app logs, and network latency via exec curl. Use profiling, trace headers, and database metrics. Cross-reference autoscaling.
Example answer:
A slow response surfaced in our product-catalog. top pods showed CPU idle but memory near limit causing GC thrash. After increasing memory limit and tuning JVM heap, latency dropped 60 percent. That holistic scan-and-fix approach comes straight from drilling basic kubernetes troubleshooting interview questions and answers.
24. How do you troubleshoot API server issues?
Why you might get asked this:
The API server is the control plane’s heart. Interviewers evaluate high-impact failure handling as part of basic kubernetes troubleshooting interview questions and answers.
How to answer:
Check kubectl cluster-info, then controller logs: journalctl -u kube-apiserver or docker logs. Inspect certificates and etcd health. Verify RBAC denying requests. Use kubectl get --raw /healthz.
Example answer:
In one incident, kubectl hung cluster-wide. /healthz showed etcd failed sync. etcd logs revealed disk full on master. Clearing logs and expanding volume brought the API back. Those high-stakes scenarios underscore why basic kubernetes troubleshooting interview questions and answers demand control plane knowledge.
25. How do you secure a Kubernetes cluster?
Why you might get asked this:
Security overlaps troubleshooting—mis-configs cause both breaches and outages. It rounds out basic kubernetes troubleshooting interview questions and answers.
How to answer:
Use RBAC least privilege, network policies, pod security standards, image scanning, secrets management, and regular patching. Mention audit logs and admission controllers.
Example answer:
We segment tiers with Calico network policies denying cross-namespace traffic. Service accounts get minimal verbs; CI pipeline scans images via Trivy. Upgrading clusters quarterly sealed CVE gaps. Demonstrating proactive security sets candidates apart in basic kubernetes troubleshooting interview questions and answers.
26. What is the difference between a Deployment and a ReplicaSet?
Why you might get asked this:
Understanding controllers clarifies rollout behavior—critical for troubleshooting. Thus it appears in basic kubernetes troubleshooting interview questions and answers.
How to answer:
ReplicaSet ensures pod replica count. Deployment manages ReplicaSets, adds rollout/rollback, strategy, and history. Describe their relationship.
Example answer:
I think of a Deployment as the brains controlling multiple ReplicaSets over time; each ReplicaSet tracks a specific pod template revision. When you kubectl apply a change, the Deployment spins a new ReplicaSet and scales down the old one. That understanding helps me debug stuck rollouts, a theme common in basic kubernetes troubleshooting interview questions and answers.
27. How do you backup Kubernetes resources?
Why you might get asked this:
Disaster recovery is part of ops hygiene. Interviewers link it to etcd knowledge in basic kubernetes troubleshooting interview questions and answers.
How to answer:
Snapshot etcd regularly; use Velero or kubectl get -o yaml redirects. Store in off-cluster storage.
Example answer:
We run etcd snapshots nightly to S3 and Velero backs up namespaces with PV snapshots. During a staging wipeout, Velero restore rebuilt deployments in minutes. Familiarity here often pops up in basic kubernetes troubleshooting interview questions and answers.
28. How do you troubleshoot persistent volume issues?
Why you might get asked this:
Stateful apps fail without storage. Interviewers test PVC/PV lifecycle—core to basic kubernetes troubleshooting interview questions and answers.
How to answer:
kubectl get pvc, pv; describe for status Pending/Failed. Check storage class, access modes, events. Inspect cloud disk status. Verify mount paths.
Example answer:
Our MySQL PVC stuck in Pending; describe pvc showed no matching storage class in the new region. Creating class gp2 fixed binding. Understanding storage provider integration comes from repeated basic kubernetes troubleshooting interview questions and answers.
29. How do you enable autoscaling for deployments?
Why you might get asked this:
Autoscaling reflects production readiness. Interviewers use it among basic kubernetes troubleshooting interview questions and answers.
How to answer:
kubectl autoscale deployment --min=2 --max=10 --cpu-percent=70 creates an HPA. Metrics-server must run. Explain tuning thresholds and custom metrics.
Example answer:
For image-render deployment, I set autoscale min=4 max=40; CPU 60 percent. Traffic spikes now trigger scale-out within 30 seconds, keeping latency below 150ms. Implementing autoscaling is a frequent talking point in basic kubernetes troubleshooting interview questions and answers.
30. How do you resolve readiness probe failures?
Why you might get asked this:
Readiness gates traffic. Failures disrupt service. Hence its place in basic kubernetes troubleshooting interview questions and answers.
How to answer:
Check pod describe to see probe path, port, scheme. Test endpoint via exec curl. Verify app startup time vs. initialDelaySeconds. Adjust thresholds or fix endpoint.
Example answer:
Our node-api readiness probe hit /status but the service moved to /ready. exec curl localhost:8080/status returned 404, proving path mismatch. Updating the probe fixed rollout. Drilling these steps when practicing basic kubernetes troubleshooting interview questions and answers ensures smooth releases.
