Hongbin, It's correct, I was involved in two big OpenStack private cloud
deployments and we never had public ips.In such case Magnum shouldn't create
any private networks, operator need to provide network id/name or it should use
default (we used to have networking selection logic in scheduler) .

said, but I think we need to address the problem that some clouds are lack of
public IP addresses. It is not uncommon that a private cloud is running without
public IP addresses, and they already figured out how to route traffics in and
out. In such case, a bay doesn’t need to have floating IPs and the NodePort
feature seems to work with the private IP address. Generally speaking, I
think it is useful to have a feature that allows bays to work without public IP
addresses. I don’t want to end up in a situation that Magnum is unusable
because the clouds don’t have enough public IP addresses. Best regards,

Kubernetes Service/NodePort
(http://kubernetes.io/docs/user-guide/services/#type-nodeport) functionality is
not going to work without public ip and this is very handy feature. ---

Subject: Re: [openstack-dev] [magnum] Are Floating IPs really needed for all
nodes? Hi yuanying, I agree to reduce the usage of floating IP. But as
far as I know, if we need to pull docker images from docker hub in nodes
floating ips are needed. To reduce the usage of floating ip, we can use proxy.
Only some nodes have floating ips, and other nodes can access docker hub by
proxy. Best Regards, Wanghua On Thu, Mar 31, 2016 at 11:19 AM, Eli Qiao

Hi Yuanying,

I think we can add option on whether to using floating ip address since IP
address are
kinds of resource which not wise to waste. On 2016年03月31日 10:40, 大塚元央 wrote:
Hi team, Previously, we had a reason why all nodes should have floating ips
[1]. But now we have a LoadBalancer features for masters [2] and minions [3].
And also minions do not necessarily need to have floating ips [4]. I think it’s
the time to remove floating ips from all nodes. I know we are using floating
ips in gate to get log files, So it’s not good idea to remove floating ips
entirely. I want to introduce `disable-floating-ips-to-nodes` parameter to
bay model. Thoughts? [1]:
