I think answering the initial question might benefit from a lot of context. I've worked on quite a few teams who built atop dotnet core (cross-platform) and also have access to auto-horizontal-scaling PAAS solutions (such as Azure App Services) and who tend to reach for Docker well before they need it. Now we all have to manage port mappings, env var mappings, file path mappings etc., the better part of a full OS-worth of abstractions when all the abstraction that we need is provided by the technologies I mentioned prior to adding Docker.
