Hi Alex,

From your message I could understand that Stein is no longer supported, but does it support ipv6, please advise.

We are also using stein to test the Upgrade feature of Triple0. We can start with Train as well and install and upgrade to Ussurie. But ipv6 support is something that we find a miss in the undercloud.conf or somewhere we can specify ipv6 details. 

Request you to please share any document/link which helps us try train on centos 8 with ipv6. For now, I am referring to this document.

Undercloud Installation — TripleO 3.0.0 documentation (openstack.org)

Thanks again for your quick response. Your response will help me decide things at the initial point only.

The commands I provided were for Train on CentOS 8.  They were not related to the original topic of the email (ipv6) but rather the container startup issues.  Stein is no longer supported and it would not be recommended to use it.

Hi Alex,

we are trying on centos 7/8, and similar commands for centos 7/8 is not working. Can you please suggest related commands for the same?

we have tried with yum/dnf in centos 7/8.

Just to confirm again we are using the stein release on centos 7 where we want to use ipv6 or dual-stack if possible.

Thanks once again for your help.

Yes IPV6 is supported, however the error you provided indicates problems starting containers.  Make sure you pin to container-tools:3.0 to ensure you get the version we expect.

    dnf module -y disable container-tools:rhel8 ;
    dnf module -y enable container-tools:3.0

Hi,

I am trying to install the undercloud using the ipv6 address on Centos 8 using Train release. 

It is seen that the deployment of undercloud is getting failed with error as mentioned below. Same deployment is working in the normal ipv4 case.

So Questions:

1. is IPV6 supported in TripleO , if yes then please suggest how.
