Wide And Name Output

Part of the Introduction to Kubernetes section of Coddy's Terminal journey. Lesson 34 of 45.

The -o flag changes what kubectl get prints. You met -o wide already: for Pods it adds the IP and the NODE, for Deployments the CONTAINERS, IMAGES and SELECTOR:

kubectl get pods -o wide
kubectl get deployments -o wide

-o name prints just the resource names, one per line, in the type/name form that other commands accept:

kubectl get pods -o name

That is handy for scripts, and for seeing at a glance what exists.

To drop the header line from any table, add --no-headers. Combined with -o wide it gives you plain rows you can feed to tools like grep.

Challenge

Beginner

Start a Pod named web from the nginx image, list the Pods with the wide format to see its IP and node, then list them with the name format.
