> What is missing in my opinion is a better container backend other than Docker (I just find it not enough for more complex scenarios, too bloated, there is the PID-1-hell, etc). With the new container runtime interface I am sure this won't be a problem in the long term.
You are in luck. Today Docker donated its low-level runtime containerd to CNCF, and a CRI implementation is on the way with the help of Google.
It fixes all three issues that you listed: it's lightweight, its API gives you complete control of the container primitives, and the PID1 bug is fixed :) It also works well with systend but doesn't require it, which is a nice plus.
