Specifically I asked this question: Looking for the Docker way to get just the 1st Repository Tag in "docker inspect" after looking for the solution for at least an hour. But after writing it I figured I could look at at the go-templates tag at stack overflow, and sure enough I found this: https://stackoverflow.com/questions/50882553/iterate-over-a-variable-number-of-items-in-a-template-slice and it worked on the 1st try.
Am I supposed to delete the question? Answer myself? Downvote myself? Currently I just feel silly.
