Hi Franck,

What you could do is to build your own image with the code changes. You can cherry-pick the commit or just apply it manually. Here in kolla-ansible docs[1] you can see how to build images with kolla-build, and here[2] you can check how to specify the built image. Could be useful for you

[1] https://docs.openstack.org/kolla/latest/admin/image-building.html
[2] https://github.com/openstack/kolla-ansible/blob/master/ansible/roles/horizon/defaults/main.yml#L106

Best regards.

Hello,
A few days ago, I asked a question about applying a patch to resolve a problem in my OpenStack environment. I didn't get a response. My question was probably stupid and not appropriate for this list. I apologize.
Having to resolve this problem, I searched high and low using search engines.
It seems that the solution, with kolla-ansible, is to upgrade to Epoxy, which takes the patch into account.
Since this update could cause other problems, I don't want to do it for the moment.
Is there another solution? Is it possible to modify the code (it's simply a line to modify in a file (https://review.opendev.org/c/openstack/horizon/+/942946)) in the two Horizon containers in my cluster? I'm really sorry if this is a stupid question, but I've been searching and can't find a method for applying these patches.
