@quixoticgeek In theory you shouldn't have to care, but...
@dalias of course you should have to care. You should know what code you're running on your machines. Even if it's abstracted into a container for easier distribution within your organisation.
@dalias those don't sound very production oriented. Using a container for R&D on your laptop, or in the dev cluster, is very different from grabbing a container from some online repo and deploying it to dozens of machines in production.
@quixoticgeek To study it. To play a game. Because a school or employer demands it. To experiment. To learn. To communicate with someone on a proprietary platform. Probably lots of other reasons.
