I agree with your pragmatism (and admire it). I would only urge you to add a couple of tools to your toolbelt for analysis:

1. Open source politics aka is the project viable? 2. Where's the money coming from? Aka, what products/companies build solutions off the tech? 3. Look for growth, not survival. If a company is not growing, it is dying.

These extra three test "gates" help me select what technology I will use, learn, and bet my career on....

Keep in mind, when this solution was adopted Docker were still wedded to Swarm. Even if they stop caring about it -- as they pretty much have now -- we have a system that works at rest. Two years on, the team(s) that handle the production support and operations are more comfortable with Docker & co, because of this. Not to forget, this is a very large (and risk-averse) enterprise. You don't always get to pick whatever you like!
