Well, I'm managing a whole fleet of Docker (and, not too long ago, LXD) containers at work. So I definitely know that ecosystem. Of course you can take any old Docker image and just run it as-is. Just as I can simply run old FreeBSD releases in jails. But that's not the whole story, is it? 3rd party dependency updates and whatnot. And yes, I feel simply deleting my jails and letting my scripts recreate them feels calm to me. I haven't had anything break or require too much attention so far. Can't say that for all the Docker stuff.
