Hello Pierre
Thank you for your help
I didn't know this command
I hope I will find a solution to have vpnaas with centos but... I'm not optimist now... Maybe the solution is Ubuntu and stringswan. 
Has someone already tried this? Vpnaas Ubuntu kolla ansible and Victoria or wallaby? I don't want to reinstall with centos stream

Hello Franck,

You can use the rpm tool from inside a container to query package information.

For example, running the following command confirms the victoria image includes libreswan-4.3-3:

docker run --rm kolla/centos-binary-neutron-l3-agent:victoria rpm -qi libreswan

Wallaby uses libreswan-4.4-1, while Ussuri uses libreswan-4.3-3 like Victoria.

Hello,
I am using kolla-ansible to set up my openstack.
I'm desperately trying to get Vpnaas to work with Victoria or Wallaby, using CentOS.
But a version of the LibreSwan software prevents proper operation.
Is it possible to know the version of a software used in a docker image ? I should not use version 4.X but rather version 3.3. I did a test with ussuri, it was version 4.3 so Vpnaas does not work with ussuri and Centos.
Thanks in advance
