Re: [gentoo-dev] rfc: /etc/hostname on gentoo

Ok all, here is what openrc-0.22 is going to do in terms of setting the host name. If /etc/hostname exists, the first word of that file will be used as the host name. Otherwise, if the value is set in /etc/conf.d/hostname it will be used. Otherwise, OpenRC will not touch the hostname. One

On second thought I put in the —hostname flags, to make it clearer. Before it was a digest from the container-id, which was not telling in the example… $ docker run -d -v /etc/ --name host1 --hostname host1 ubuntu tail -f /dev/null 6a85473421368051efec9b6f55991a5c3b4150c575a0724695cdad99f7a26e06

Hey there, as for the /etc/hostname when sharing /etc/ as a volume… This ain’t a problem as /etc/hostname is taken care of by the docker-engine (in previous versions they used it to discover other hosts). As you can see in the snippet below, /etc/hostname is local, while it is possible to create

Hey Rich, nice idea, but unfortunately this provides the hostname of the container itself. $ docker run -ti -v /proc/sys/kernel/hostname:/etc/docker-hostname:ro nginx bash root@bea048d42fc3:/# cat /etc/docker-hostname bea048d42fc3 root@bea048d42fc3:/# Without digging deep into it I reckon that
