[Starlingx-discuss] IPv6 issue when apply OpenStack on IPv6 simplex.

[Liu, ZhipengS]

Thanks Joseph!
I guess it can go further.
But keystone-db failed, which is the same as I met in my another ipv4 setup.
I will build an EB based on a latest green daily build.
The patch will come soon for your review.

Thanks!

Great!
We definitely did support this before openstack-helm and openstack-helm-infra were upversioned around December.

You should be able to control this in the rabbitmq helm plugin, so you can modify the behaviour based on ip version.
https://github.com/starlingx/config/blob/master/sysinv/sysinv/sysinv/sysinv/helm/rabbitmq.py

Once you get passed this point, does everything else come up as well?  Does the app successfully apply?

Hi Joseph,



I fixed this issue now!!

After check port status by sudo ip -all netns exec lsof -I, it shows that Rabbitmq only bind 15672 to ipv4.

I add below changes and pass the rabbitmq deployment.

conf:

      rabbitmq:

        management.listener.port: 15672

       management.listener.ip: "::"



Next step: I have to think how to submit this patch to support both ipv4 and ipv6



BTW, are you sure we passed this test before using OpenStack- train version?

If not change helm chart, how can we pass it?



Thanks!

Zhipeng

Hi Joseph,



Below is my patch to make rabbitmq pod start in ipv6 setup.(This is not a formal patch)
