1fill in blank

easy

Complete the command to create a ConfigMap named my-config from a literal key-value pair.

💡 Hint

Common Mistakes

Using colon ':' instead of equal sign '='.

Adding extra equal signs in the literal.

Using underscores instead of equal sign.

The correct syntax for creating a ConfigMap from a literal is key=value, so 'app=frontend' is correct.

2fill in blank

medium

Complete the command to create a ConfigMap named settings with two literals: mode=production and debug=false.

Kubernetes

kubectl create configmap settings --from-literal=mode=production [1]

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

A--from-literal=debug=false

B--from-literal debug=false

C--from-literal:debug=false

D--from-literal debug:false

💡 Hint

Common Mistakes

Using space instead of equal sign after --from-literal.

Using colon ':' instead of equal sign '='.

Combining literals without repeating --from-literal.

Each literal must be passed with --from-literal=key=value, so '--from-literal=debug=false' is correct.

3fill in blank

hard

Fix the error in the command to create a ConfigMap named app-config with a literal key 'version' and value '1.0'.

Kubernetes

kubectl create configmap app-config --from-literal=version[1]1.0

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

B-

C==

D=

💡 Hint

Common Mistakes

Using colon ':' instead of equal sign.

Using double equal signs '=='.

Using dash '-' instead of equal sign.

The correct syntax uses '=' between key and value in literals.

4fill in blank

hard

Fill both blanks to create a ConfigMap named config with literals for environment=dev and debug=true.

Kubernetes

kubectl create configmap config [1] [2]

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

A--from-literal=environment=dev

B--from-literal environment=dev

C--from-literal=debug=true

D--from-literal debug=true

💡 Hint

Common Mistakes

Using space instead of equal sign after --from-literal.

Not repeating --from-literal for each literal.

Using colon ':' instead of equal sign '='.

Each literal must be passed with --from-literal=key=value, so blanks are filled with '--from-literal=environment=dev' and '--from-literal=debug=true'.

5fill in blank

hard

Fill all three blanks to create a ConfigMap named full-config with literals: host=localhost, port=8080, and debug=false.

Kubernetes

kubectl create configmap full-config [1] [2] [3]

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

A--from-literal=host=localhost

B--from-literal=port=8080

C--from-literal=debug=false

D--from-literal host=localhost
