Which command correctly creates a ConfigMap named config-data from the file app.env?

Akubectl apply configmap config-data --from-file=app.env

Bkubectl create configmap config-data -f app.env

Ckubectl create configmap config-data --from-file=app.env

Dkubectl configmap create config-data --file=app.env

Step-by-Step Solution

Solution:

Step 1: Identify the correct command syntax
The correct command to create a ConfigMap from a file uses kubectl create configmap followed by the name and --from-file option.
Step 2: Analyze options
kubectl create configmap config-data --from-file=app.env uses the correct syntax. kubectl create configmap config-data -f app.env uses -f which is incorrect here. kubectl apply configmap config-data --from-file=app.env uses apply which is for applying manifests, not creating ConfigMaps directly. kubectl configmap create config-data --file=app.env uses an invalid command.
Final Answer:
kubectl create configmap config-data --from-file=app.env -> Option C
Quick Check:
Check for kubectl create configmap NAME --from-file=FILE syntax [OK]

Quick Trick: Use 'kubectl create configmap NAME --from-file=FILE' [OK]
