To contain, or not to contain: That is the question

I confess the line "For most use cases, containerizing a legacy application is worth the effort as the benefits far outweigh the risks." needs a huge citation for me to believe it.

Docker and friends seems to be winning so much from inertia and fear of choosing otherwise than any benefits they actually have. In particular, it is considerable the number of tools that no longer work in the containerized world.

And we are still not back to the point where it seems java's warfile ecosystem was about a decade ago.
