Doc Type: Known Issue
Doc Text:
Currently, certain setup steps require a SSH connection to the overcloud controllers, and will need to traverse VIPs to reach the Overcloud nodes. If your environment is using an external load balancer, then these steps are not likely to successfully connect. You can work around this issue by configuring the external load balancer to forward port 22. As a result, the SSH connection to the VIP will succeed.

Description Giulio Fidente 2015-09-25 15:58:39 UTC
Description of problem:

_perform_pki_initialization from os-cloud-config:

https://github.com/openstack/os-cloud-config/blob/master/os_cloud_config/keystone.py#L484

requires SSH on the Overcloud nodes.

We should avoid that instead and (probably) do it from puppet. This is problematic especially when using an external load balancer because in such a scenario the VIP (which is currently used to SSH on one of the Overcloud nodes) is not hosted by any of the controllers and the post-deployment initialization fails unless appropriate port forwarding is configured on the external balancer.

Comment 2 Giulio Fidente 2015-09-25 16:01:36 UTC
I have assigned it against THT because there it goes if we decide to do pki_setup via puppet ... this requires updates into os-cloud-config as well though.

Hi,

This problem is hitting me now on CI.

So when you have a patch I can test it.

Cheers!
