FUSE filesystem for LXC, offering the following features:
- a cgroupfs compatible view for unprivileged containers
- a set of cgroup-aware files:
- cpuinfo
- meminfo
- stat
- uptime
In other words, it will provide an emulated /proc and /sys/fs/cgroup folder for the containers.
The recommended command to run lxcfs is:
sudo mkdir -p /var/lib/lxcfs
sudo lxcfs -s -f -o allow_other /var/lib/lxcfs
- -s is required to turn off multi-threading as libnih-dbus isn't thread safe.
- -f is to keep lxcfs running in the foreground
- -o allow_other is required to have non-root user be able to access the filesystem
- -d can also be passed in order to debug lxcfs
In order to use lxcfs with systemd-based containers, you can either use
LXC 1.1 in which case it should work automatically, or otherwise, copy
the lxc.mount.hook and lxc.reboot.hook files (once built) from this tree to
/usr/share/lxcfs, make sure it is executable, then add the
following lines to your container configuration:
lxc.mount.auto = cgroup:mixed
lxc.autodev = 1
lxc.kmsg = 0
lxc.include = /usr/share/lxc/config/common.conf.d/00-lxcfs.conf
