There are many usage cases of kubernetes and, hence, very distinct support scenarios when it deals to supporting a kubernetes issue. In my experience, I would call the following basic kubernetes commands to investigate an issue, as the most useful -and necessary- to accompany any kubernetes issue report.
kubectl version kubectl cluster-info kubectl get nodes -o wide kubectl get pods --all-namespaces -o wide kubectl get deployments --all-namespaces kubectl get svc --all-namespaces -o wide
On the same time, I would include these couple of Docker commands:
To speed up any kubernetes troubleshooting, I’d recommend to provide the output of those commands in TXT format, rather than taking a screenshot.
Do you have any other experienced-based basic kubernetes command you would add to this list? Please share in the comments section.
