Linux containers in 500 lines of code (2016)

I was actually wondering what the lowest-resource way of launching a bunch of mostly-idle single port applications in isolation currently is. Docker runtime is bloated, Kubernetes has recommended limits (and enforced on cloud providers), Runc feels like you have to implement Kubernetes/Docker on top yourself. Anyone seen anything else out there to run a few thousand single port binaries and multiplex them with a webserver?

Podman with the new crun[1] container runtime is pretty lightweight. Everything circles back to C.

I’ve had really good results with LXC/LXD. Depending on the privileges of the container the only area of overhead that sometimes concerns me is filesystem IO, but ive been able to work around it.

Under the hood docker uses `runc` which is fairly small and easy to use, IMO.
