💡 Hint

Using a wrong namespace name like 'kube-system' when checking default pods.

The default namespace is the standard namespace where pods run if no other namespace is specified.

💡 Hint

Common Mistakes

Using 'list' or 'create' which do not show pod details.

The describe command shows detailed information about a specific pod.

💡 Hint

Common Mistakes

Adding extra commands like 'get pods' or 'describe' after 'logs'.

The kubectl logs command requires the pod name as the argument to fetch logs.

4fill in blank

hard

Fill both blanks to create a command that watches pod status changes every 2 seconds.

Kubernetes

watch --[1]=[2] kubectl get pods -n default

Drag options to blanks, or click blank then click option'

Btimeout

C2s

D5s

Attempts:

💡 Hint

Common Mistakes

Using 'timeout' instead of 'interval' or wrong time values.

The --interval=2s option makes the watch command refresh the pod status every 2 seconds.

5fill in blank

hard

Fill all three blanks to create a command that labels all pods with 'env=prod' in the 'default' namespace.

Kubernetes

kubectl label pods -n default [1] [2]=[3]

Drag options to blanks, or click blank then click option'

A--all

Benv

Cprod

D--selector

Common Mistakes

Using '--selector' instead of '--all' to select pods.

The --all flag selects all pods, and env=prod sets the label key and value.
