Which command can be used to create a Kubernetes ConfigMap with specific values using the CLI?

• A. kubectl create configmap colour-configmap --from-literal=COLOUR=red --from-literal=KEY=value
• B. kubectl apply -f configmap.yaml
• C. kubectl create secret generic colour-configmap
• D. kubectl get configmap

Answer: (A)

Creating a ConfigMap from the CLI by supplying literal key-value pairs. The command uses the kubectl create configmap mechanism and attaches data directly on the command line with --from-literal, specifying two keys: COLOUR with value red and KEY with value. This directly builds the ConfigMap named colour-configmap without needing a manifest file, which is exactly what’s being tested—creating a ConfigMap with specific values via the CLI. The other options either create from a file (apply -f configmap.yaml), create a different resource (a Secret), or just retrieve a ConfigMap (get configmap) rather than create one.
