[Lxc-users] Use host syslog socket in container

[Vallevand, Mark K]

Here is how I got syslog to work with a program running in a container.  After creating a container, do something like this:

echo syslog setup
cat <<EOF > /etc/rsyslog.d/99-lxc-1.conf
\$AddUnixListenSocket /var/lib/lxc/container1/rootfs/dev/log
EOF
restart rsyslog

If you are using rsyslog, of course.  The rsyslog daemon only supports 100 unix domain sockets.  So, I guess that means 1 for the host /dev/log and 99 more for containers.

My program happily uses syslog and they end up in the host syslog.

Subject: Use host syslog socket in container

I am running a program in a container.  The program uses syslog and I'd like the /dev/log socket in the container to refer to /dev/log in the host file system.

Suggestions?
