juju status can't resolve hostname

Question

I'm trying to install a private cloud with Ubuntu Server 11.10. I've successfully installed orchestra by following the below tutorial:

• http://cloud.ubuntu.com/2011/09/oneiric-server-deploy-server-fleets-p1/

Then I've followed this tutorial to install and configure juju:

• https://help.ubuntu.com/community/UbuntuCloudInfrastructure

The juju bootstrap command finished successful and by booting the machine it installed ubuntu server. When I then try to run the juju status command I get the following error:

juju -v status

I guess there is a problem with resolving the hostname I've set for the system in Orchestra. I can ping the machine correctly by using its IP address.

Is there a way to configure juju to use IP addresses instead of hostnames? Or is this rather a bug in Orchestra/Juju and the default DHCP configuration set during the installation of Orchestra?

Answer 1

Unfortunately no, juju and orchestra need DNS to work and agree between clients and the juju managed machines. You can "fake it" by editing the /etc/hosts files on all the machines to be correct if you haven't set up orchestra's built in dnsmasq server to do DHCP and DNS, which is the simplest method, but requires a dedicated network for your managed machines (since it would fight with an existing DHCP server).
