> the sysadmin doesn't need to learn how the container was built just to manage services or deploy new instances I disagree on that point. Just taking a docker image from a developer and deploying that to production does not work to well in my experience, and guess who gets the support calls when things break? If a sysadmin gets a say in how the container images are configured, it usually works out much better. Also partitioning the filesystem to avoid dependency clashes used to be more important when I used rack mounted servers. Now it's easy enough to deploy separate cloud instances to partition things. And it's a real VM with real tools on it so I can diagnose problems if they arise.
