Hi Wodel,In your case don't use kolla<14 version. Use the same version or newer version to build containers.Use the official documentation: https://docs.openstack.org/kolla/latest/admin/image-building.htmlOn Tue, May 16, 2023 at 11:52 AM wodel youchi <wodel.youchi@gmail.com> wrote:Hi,Could you help me understand the process of building kolla containers from source?I am not a developer but I want to be to build containers rapidly especially when there is an urgent patch.I am using Yoga branch which is the 14th version, do I need to use the same version of kolla-build to build containers or it matters not?Regards.--Regards,Maksim Malchuk
