I agree with respect to admiring it from afar. I've gone through large chunks of the source many times and always have an appreciation for what it does and how it accomplishes it. It has a great, supportive community around it as well (if not a tiny bit proselytizing at times, which doesn't bother me really).

With all that said, while I have no "hate" for the stack, I still have no plans to migrate our container infrastructure to it now or in the foreseeable future. I say that precisely because I've seen the source, not in spite of it. The net ROI on subsuming that level of complexity for most application ecosystems just doesn't strike me as obvious.
