Kubernetes Logs Retrieval Documentation

Accessing Pod Logs

Connect to VPS using

ssh <user>@<host> -o PreferredAuthentications=password -o PubkeyAuthentication=no

To retrieve logs from a specific pod, use the following command:

kubectl logs <pod-name> -n <namespace>

This command retrieves the logs for the pod. Replace <pod-name> with the name of the pod you want to inspect.

To stream the logs in real-time, use the -f flag:

kubectl logs -f <pod-name>

To view logs from a previously terminated pod, add the --previous flag:

kubectl logs <pod-name> --previous

To retrieve logs from multiple pods that share the same label, you can use:

kubectl logs -l <label-selector>

To filter logs from specific pods or applications based on their labels:

kubectl logs --since=<time>

Example:

kubectl logs <pod-name> --since=1h

List existing pods:
```
kubectl get pods -n <namespace>
```
Multiple Lines: If logs are too long, limit them with the --tail flag:
```
kubectl logs <pod-name> --tail=100
```
