[Bug 1389954] Re: Make .lxc domain name resolution easier to discover and enable
Tried to follow the documentation on Ubuntu Server 15.04 with no luck. I have activated LXC_DOMAIN="lxc" in /etc/default/lxc-net, then created /etc/dnsmasq.conf and added server=/lxc/10.0.3.1 (there is no NetworkManager installed). Tried to reboot, but still getting "ping: unknown host container.lxc". It seems that dnsmasq doesn't read the config. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1389954 Title: Make .lxc domain name resolution easier to discover and enable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1389954/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Yes, lxc-net is called lxc-net in all init systems where the job exists (syv, upstart, systemd) Both lxc-net and network-manager need to be restarted (unless network- manager is smart and uses inotify to look for updates).

[Bug 1389954] Re: Make .lxc domain name resolution easier to discover and enable
Okay, I've written up a short README.Debian describing the necessary changes to /etc/default/lxc-net and the dnsmasq config file. I don't remember what steps are necessary to make the domain names accessible, though, and I'd like to include those steps in the readme. Do I have to restart the lxc-net service? (And is that service called the same thing regardless of whether sysv init, upstart, or systemd is in use?) Do I have to restart NetworkManager?

Thanks for taking an interest in the issue.

[Bug 1389954] Re: Make .lxc domain name resolution easier to discover and enable
This has been discussed before. I definately want to make things work as cleanly as possible out of the box. There are a few problems with doing htis though, 1) networkmanager isn't the only place we'd need to do this (most "serious" lxc hosts probably don't run networkmanager), 2) if we do this automatically then changes made to /etc/default/lxc-net may start to require more baroque changes elsewhere. We almost want a simple tool to administer all the network bits at this point. Another possiblity is to leave fixing this to lxd. ** Changed in: lxc (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1389954 Title: Make .lxc domain name resolution easier to discover and enable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1389954/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
