End: Analyze Output

First, list pods to find the pod name. Then use 'kubectl describe pod' to see details or 'kubectl logs pod' to see logs.

Execution Sample

Kubernetes

kubectl get pods
kubectl describe pod my-pod
kubectl logs my-pod

List pods, then show details and logs of a specific pod named 'my-pod'.

Process Table

Step	Command	Action	Output Summary
1	kubectl get pods	List all pods in current namespace	Displays pod names, statuses, and age
2	kubectl describe pod my-pod	Show detailed info about 'my-pod'	Shows pod metadata, status, containers, events
3	kubectl logs my-pod	Show logs from 'my-pod' containers	Outputs container logs line by line
4	-	End of commands	No further output

Status Tracker

Variable	Start	After Step 1	After Step 2	After Step 3
pod_list	empty	['my-pod', 'other-pod']	unchanged	unchanged
selected_pod	none	none	'my-pod'	'my-pod'
pod_details	none	none	metadata + status + events	unchanged
pod_logs	none	none	none	log lines from container

Key Moments - 2 Insights

Why do we run 'kubectl get pods' before describing or viewing logs?

Because 'kubectl get pods' shows the pod names available, so you know which pod to describe or get logs from, as seen in execution_table step 1.

What is the difference between 'kubectl describe pod' and 'kubectl logs'?

'kubectl describe pod' shows detailed pod info like status and events, while 'kubectl logs' shows the actual output from the pod's containers, as shown in steps 2 and 3.

Concept Snapshot

kubectl get pods  # List pods in namespace
kubectl describe pod <pod-name>  # Show detailed pod info
kubectl logs <pod-name>  # Show container logs
Use get pods first to find pod names
Describe shows status and events
Logs show what the pod outputs

Full Transcript

To view pod details and logs, first run 'kubectl get pods' to list all pods and find the pod name. Then use 'kubectl describe pod <pod-name>' to see detailed information like status, containers, and events. To see what the pod is printing, run 'kubectl logs <pod-name>'. This sequence helps you understand pod state and troubleshoot by checking logs.
