A cleaner way to do this comparison might be something like:
[[ ${ENVIRONMENT} =~ "production" ]] && echo "..."

I needed this to be able to use [[ with Linux.

Can't you do it like this instead of using the long-form if?
@echo $(shell [[ ${ENVIRONMENT} =~ "production" ]] && echo "...")

I'll give that a try.

I got the short form working (shown below) but it will leave a blank space if the environment it is checking for was not applied. Is that going to be OK?
@echo $(shell [[ "${ENVIRONMENT}" =~ "production" ]] && echo "switch to production cluster: kubectl config use-context $(shell kubectl config get-contexts -o name | grep ${NAME}-production)")

Sure, that's fine for now. Thanks!

It's possible it would work with @echo -n but I wouldn't worry about it.

I tried using -n but that also removed the newline in the case where there was text to show. Also tried using printf with a \n but that didn't work either. I'm going to merge it as is but I'll keep trying to find a better way to do this.
