💡 Hint

Common Mistakes

Using 'logs' shows container logs, not pod details.

The describe command shows detailed information about the pod, including events and status.

💡 Hint

Common Mistakes

Using '--container' is valid but requires container name, not index.

The -c option specifies the container name or index for logs.

4fill in blank

hard

Fill both blanks to create a command that restarts a pod named 'myapp-pod' by deleting it.

Kubernetes

kubectl [1] pod myapp-pod [2]

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

Adelete

Brestart

C--force

D--grace-period=0

Attempts:

💡 Hint

Common Mistakes

Using 'restart' is not a valid kubectl command.

Deleting a pod with --grace-period=0 forces immediate termination, effectively restarting it if managed by a controller.

5fill in blank

hard

Fill all three blanks to create a command that patches a pod 'myapp-pod' to add an environment variable 'DEBUG' with value 'true'.

Kubernetes

kubectl patch pod myapp-pod -p '{{"spec": [1]' --type=[2] [3]

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

A{"containers":[{"name":"myapp-container","env":[{"name":"DEBUG","value":"true"}]}]}

Bjson

C--namespace=default

Dmerge

💡 Hint

Common Mistakes

Using wrong patch type or missing namespace option.

The patch JSON adds the environment variable. The patch type is 'merge'. The namespace option specifies the default namespace.
