Technically both, but more so the former. I had a heck of a time finding accurate docs on the correct apiVersion to use for things like my ingress and service files (they had a nasty habit of doing beta versions and changing config patterns w/ little backwards compatibility). This was a few years back when your options were a lot of Googling, SO, etc, so the info I found was mixed/spotty. As a solo founder, I found what worked at the time and assumed (foolishly, in retrospect) that it would just continue to work as my needs were modest.
