If you are struggling to crack DevOps interviews related to Kubernetes or want to get real time exposure on Kubernetes you can learn it from here ….I am working on the same domain to manage more than 300+ Kubernetes cluster in my company… so on my day to day task that what all issues I faced in my project based on that I have created the Real time use cases so that other one also get real time exposure on Kubernetes if they don’t get chance to work in real time project they can learn easily and more confident during interview

⸻ Common Reasons for Pending Pods 1. Insufficient Resources (CPU/Memory) • No nodes have enough available CPU or memory to fit the pod’s resource requests. • Check: kubectl describe pod <pod-name> → Look for messages like “0/3 nodes are available: insufficient memory.” 2. Node Selectors / Taints and Tolerations • Pod specifies a nodeSelector or nodeAffinity that doesn’t match any available node. • Or the nodes are tainted and the pod doesn’t tolerate those taints. • Check: kubectl describe pod or examine the pod spec. 3. PersistentVolumeClaims (PVCs) Not Bound • If the pod needs a PVC and the claim is not bound to a volume yet. • Check: kubectl get pvc, and also describe the PVC. 4. ImagePull Issues • Kubernetes can’t pull the container image (wrong image name, no access, etc.), but note: image pull errors often move the pod to ContainerCreating or ImagePullBackOff, not Pending. • Check: Still helpful to look at: kubectl describe pod → Events section. 5. Pod Quotas / LimitRanges • The namespace has reached its quota, or the pod’s resource requests don’t align with set LimitRange policies. • Check: kubectl describe quota or kubectl describe limitrange.
