In the container that fails to start systemd, some mount points are absent, that present in the other containers: configfs on /sys/kernel/config type configfs (rw,relatime) debugfs on /sys/kernel/debug type debugfs (rw,relatime,seclabel) systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=30,pgrp=1,timeout=0,minproto=5,maxproto=5,direct,pipe_ino=604626) After applying configuration for sysctl and limits.conf from https://github.com/lxc/lxd/blob/master/doc/production-setup.md problem has disappeared. Closing as NOTABUG. |
Created attachment 1311253 [details] Dockerfile and shell scripts Description of problem: I'm running docker containers with Fedora 26 and systemd inside. But I can't start more than 24 (sometimes 25 or 26) containers. It's reproducible on different systems. Problem appeared in Fedora 26 with systemd-233. If I downgrade systemd in the container 232, I no longer observe the problem. Version-Release number of selected component (if applicable): systemd-233-6.fc26.x86_64 How reproducible: always Steps to Reproduce: From the attached reproducer: 1. Build the container: ./build.sh 2. Spin up 50 containers: ./run.sh 3. docker ps -q | wc -l 24 4. Optionally run cleanup.sh
