💡 Hint

Common Mistakes

Omitting the resource type prefix like 'pod/'

Using service or deployment instead of pod

You need to specify the pod with the prefix pod/ to debug it directly.

medium

Complete the command to create a debug pod named 'debugger' based on pod 'api-server'.

Kubernetes

kubectl debug api-server --[1]=debugger --image=busybox

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

Acopy-to

Bcontainer

Csidecar

Dinit-container

💡 Hint

Common Mistakes

Using --container instead of --copy-to

Using --sidecar or --init-container which are not valid flags here

The --copy-to flag creates a new debug pod named 'debugger'.

3fill in blank

hard

Fix the error in the command to debug pod 'db' by adding an interactive shell.

Kubernetes

kubectl debug pod/db --image=busybox [1]

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

A-d

B-it

C--restart=Never

D--rm

Attempts:

💡 Hint

Common Mistakes

Using -d which runs container detached

Using --restart=Never which controls pod restart policy

Using --rm which removes container after exit but doesn't make it interactive

The -it flag makes the container interactive with a terminal shell.

4fill in blank

hard

Fill both blanks to create a debug pod named 'test-debug' from pod 'backend' with no restart.

Kubernetes

kubectl debug pod/backend --[1]=test-debug --[2]=Never --image=busybox

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

Acopy-to

Brestart

Crestart-policy

Dcontainer

Attempts:

💡 Hint

Common Mistakes

Using --restart-policy instead of --restart

Using --container instead of --copy-to

Use --copy-to to name the debug pod and --restart=Never to prevent restarts.

5fill in blank

hard

Fill all three blanks to create a debug pod named 'debugger' based on pod 'cache' with image 'busybox' and interactive shell.

Kubernetes

kubectl debug pod/cache --[1]=debugger --image=[2] [3]

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

Acopy-to

Bbusybox

C-it

Dcontainer

Attempts:

💡 Hint

Common Mistakes

Using --container instead of --copy-to

Forgetting -it for interactive shell

Using wrong image name

Use --copy-to to name the debug pod, specify the image busybox, and -it for interactive shell.
