Practice - 5 Tasks

1fill in blank

easy

💡 Hint

Common Mistakes

Using 'config' or 'context' as namespace names, which are invalid.

The command sets the current context's namespace to the specified one, here 'production'.

2fill in blank

medium

Complete the command to view the current namespace in kubectl context.

Kubernetes

kubectl config view --minify [1]

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

A-A

B-o jsonpath='{.contexts[0].context.namespace}'

C-o yaml

D-v

💡 Hint

Common Mistakes

Using grep without proper output formatting, causing no output.

This command extracts the current namespace from the kubectl config using jsonpath.

3fill in blank

hard

Fix the error in the command to switch namespace context.

Kubernetes

kubectl config set-context [1] --namespace=staging

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

A--current

Bcurrent

C--context

Dcontext

💡 Hint

Common Mistakes

Using 'current' without dashes or '--context' which changes a named context.

The correct flag to modify the current context is '--current'.

4fill in blank

hard

Fill both blanks to create a command that switches to the 'dev' namespace and then lists pods.

Kubernetes

kubectl config set-context [1] --namespace=[2] && kubectl get pods

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

A--current

Bdev

Cdefault

D--namespace

Attempts:

💡 Hint

Common Mistakes

Using '--namespace' as the first blank or 'default' instead of 'dev'.

Use '--current' to modify the current context and 'dev' as the namespace name.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps pod names to their statuses for pods in the current namespace.

Kubernetes

pods_status = { [1]: [2].status.phase for [3] in pods.items() }

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

Apod.metadata.name

Bpod

D{

💡 Hint

Common Mistakes

Not starting with '{', or using wrong variable names.

The dictionary comprehension {pod.metadata.name: pod.status.phase for pod in pods.items()} maps pod names to their status phases.
