Sysbox container with Ubuntu 21.10 + Docker (focal) fails to run properly

[ctalledo]

Running a container with Ubuntu 21.10 + systemd + docker (focal), launched with Docker 20.10.9 + Sysbox v0.4.1 fails:

$ docker run --runtime=sysbox-runc -it --rm --name test-1 --hostname test-1 ghcr.io/nestybox/ubuntu-impish-systemd-docker:latest
...
[  OK  ] Started OpenBSD Secure Shell server.
[FAILED] Failed to start containerd container runtime.
See 'systemctl status containerd.service' for details.
[DEPEND] Dependency failed for Docker Application Container Engine.
[  OK  ] Started User Login Management.
...

Running Docker within this Sysbox container causes it to crash.

Needs investigation, but it's very likely related to the problem described here (not related to Sysbox per-se):

FYI: I was able to run a container image with Ubuntu Impish + systemd without problem, using Docker 20.10.9 + Sysbox top-of-tree (see below). This suggests the problem is specific to running Docker inside the Ubuntu Impish container.

root@sysbox-test:~/nestybox/sysbox# docker --version

I was not able however to create an image with Ubuntu Impish + systemd + Docker following the usual Docker installation steps.

Apparently Docker has not yet added support for it; see here.

Right, i had to rely on focal's repo to be able to generate my impish-systemd-docker image.

This is no longer reproducing (must have gotten fix in a recent change). Closing.
