Even rancher no longer uses container manager as pid 1; these systems being discussed are minimal not single binary. (Only systemd is putting some "container management" features into pid 1).
- icebraining 10y agoWhich container management features is systemd putting into pid 1?
- cyphar 10y agomachinectl and systemd-nspawn. Namely, systemd now manages container processes if you ask it to. My experience with the systemd cgroup handling doesn't fill me with much faith on this topic.
- icebraining 10y agosystemd does manage containers, but from what I can tell, that functionality is not in PID 1, is it?
- cyphar 10y agoHi Justin :D My point was that even with everything on a system running in a container, you still need a general-purpose OS inside the container to do management. Not that in particular that a single-binary container-manager-as-init was the only case where that's true.
