[Rdo-list] Packstack Icehouse changes

Hello, I was working on integrating a neutron plugin in Packstack and successfully done so for the Packstack havana. I then tried porting the changes into Packstack for icehouse and noticed some changes that limit my options: 1. We need to run the metadata agents on all the compute nodes so we previously used the CONFIG_NEUTRON_METADATA_HOSTS option to specify this. In the latest version this was deprecated and replaced by CONFIG_NETWORK_HOSTS so the metadata agent will only be installed on the network node. 2. The CONFIG_CONTROLLER_HOST replaces several other options including CONFIG_HORIZON_HOST. In our setup we need to run horizon on the public network and the other services on the private network. The missing CONFIG_HORIZON_HOST means that the dashboard will only be available on our private network and we need to manually update the horizon and httpd config files. 3. The CONFIG_NOVA_VNCPROXY_HOST was also replaced by CONFIG_CONTROLLER_HOST so the VM console doesn't work outside our private network. 4. An issue that I've encountered when running packstack was a mysql puppet error "service mysqld start failed: my_default_config doesn't take the --mysqld parameter". The mysqld service started when I tried from the command line and after that Packstack worked. Not sure it's related to Packstack or some mysql server issue on our machines. The servers we use have CentOS 6.5 installed. I know that having only three types of hosts (CONTROLLER, NETWORK, and COMPUTE) simplifies things when installing basic Openstack configurations (with the ml2, linux bridge, or ovs plugin), but for us it becomes a lot more complicated to make Packstack do what we need. I believe that these changes affect Packstacks' flexibility. Now we cannot install horizon, cinder, swift, or keystone on a different host because they are tied to the CONFIG_CONTROLLER_HOST option. Is there a way to override the CONFIG_CONTROLLER_HOST, CONFIG_NETWORK_HOSTS, and CONFIG_COMPUTE_HOSTS? Can packstack havana be used to install Openstack icehouse by configuring yum to use the icehouse rdo repository? Regards, Stefan A
