Hello everyone. Here's a problem I can't solve. In my test cluster (2 nodes, Ubuntu 2022.4, Cinder LVM, kolla-ansible Antelope, 2023.1) everything is fine. In a month, my students will be able to start from scratch and build an Openstack cluster with quite a few features in around twenty hours. The challenge is to guide them in building a cluster, ensuring that they seek to solve problems, without it being too difficult. So you have to guide them, start with virtual machines then move on to real servers. In the end, I wanted to test "magnum" because they know Kubernetes. I edit globals.yml, reconfigure, grab Fedorac-coreos (qcow2 file) and add the image to peek. In Horizon, I create a cluster template. everything is working. Then, with the admin account, I try to create a cluster from the model and there I have the problem Failed to create trustee XXX in domain XXX”
Okay, I create the file /etc/kolla/config/magnum.conf with enable_cluster_user_trust = True I reconfigure but it doesn't work.
I'm looking for other solutions but I can't find them. Should we give special rights to the admin user (for my example) on the magnum domain?
