I am trying to understand how kernel modules are "passed" to nspawn container.
My setup: Archlinux host, Fedora 23 container (function = server). Example of what I would like to solve: On container: ------------------------------------------------------------------------------ $ systemctl status docker -l ● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since Sun 2015-11-08 10:44:27 CET; 2h 27min ago Docs: http://docs.docker.com Main PID: 1146 (code=exited, status=1/FAILURE) Nov 08 10:44:27 poppy docker[1146]: time="2015-11-08T10:44:27.846565995+01:00" level=warning msg="Docker could not enable SELinux on the host system" Nov 08 10:44:27 poppy docker[1146]: time="2015-11-08T10:44:27.846925084+01:00" level=info msg="Option DefaultDriver: bridge" Nov 08 10:44:27 poppy docker[1146]: time="2015-11-08T10:44:27.846948089+01:00" level=info msg="Option DefaultNetwork: bridge" Nov 08 10:44:27 poppy docker[1146]: time="2015-11-08T10:44:27.848252833+01:00" level=warning msg="Running modprobe bridge nf_nat br_netfilter failed with message: , error: exit status 1" Nov 08 10:44:27 poppy docker[1146]: time="2015-11-08T10:44:27.852710572+01:00" level=info msg="Firewalld running: true" Nov 08 10:44:27 poppy docker[1146]: time="2015-11-08T10:44:27.918262393+01:00" level=fatal msg="Error starting daemon: Error initializing network controller: Error initializing bridge driver: Setup IP forwarding failed: open /proc/sys/net/ipv4/ip_forward: read-only file system" Nov 08 10:44:27 poppy systemd[1]: docker.service: Main process exited, code=exited, status=1/FAILURE Nov 08 10:44:27 poppy systemd[1]: Failed to start Docker Application Container Engine. ------------------------------------------------------------ 1- SELinux is disabled as the host distro is difficult to setup with it, so it is OK 2- Running modprobe bridge nf_nat br_netfilter failed with message: , error: exit status 1" These modules are indeed loaded on host. How can I make the container aware of it? Thank you for any pointers/help. -- google.com/+arnaudgabourygabx _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
