Mostly web applications actually. Most web stuff is not that complicated. Usually the deployment itself is from docker (ops insists) but I just do development without it and I've never had a problem. I understand in theory I could get mismatched versions of things from production and thereby introduce a bug; in practice this has never happened a single time.
Right, yeah - I'm specifically _not_ talking about development (I agree that the likelihood of mismatches causing bugs is so small as to be worth fixing as that arises, rather than wasting effort on building a containerized dev environment), but about deployment. How could you deploy without first containerizing your application?
