Hi all,
Thanks for your inputs. We discussed this proposal in our team meeting [1], and we all agreed to support an option to remove the need of floating IPs. A blueprint was created for implementing this feature: https://blueprints.launchpad.net/magnum/+spec/bay-with-no-floating-ips . Please feel free to assign it to yourselves if you interest to implement it. Thanks.

Best regards,

Hi Egor,

I know some people still want to use floating ips to connect nodes,
So I will not remove floating ips feature completely.
Only introduce the option which will disable to assign floating ip to nodes.
Because some people doesn’t want to assign floating ip to nodes.

Thanks

who is going to run/support this proxy? also keep in mind that 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.

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.

Wanghua

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.

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?
