How do you create configmap cm1 with value PORT=8080?

Explanation:
ConfigMaps hold configuration data as key-value pairs, and you can supply those values inline with --from-literal. To create a configmap named cm1 that contains PORT=8080, use: oc create configmap cm1 --from-literal PORT=8080. This directly defines the key PORT with the value 8080 inside the new configmap. The other forms aren’t appropriate here: oc createconfig is not valid syntax, you need a space between create and configmap. Using from-file would populate the configmap from contents of a file rather than a direct literal. Adding --namespace would place the configmap in a specific namespace, which isn’t required unless you’re targeting a particular namespace.
