Hey Kamil, There will be an error in one of the environment files that you’re including in your overcloud deploy command. You said it’s your first deployment that was already prepared for you. Does this mean that the environment has already been deployed and you are trying to make a change now? If that’s the case, then I would check any of the files that have changed between the initial deployment and what you’re trying to do now. Regards, Brendan Shephard Senior Software Engineer

 Hello, I'm trying to deploy openstack wallaby on centos9. Undercloud is running, but when I run "openstack overcloud deploy" it ends up with error:

It is my first tripleo deployment which was already prepared by the customer, but is not working currently. It is wallaby deployment on centos stream 9.

Can somebody give me advice on what is the best way to troubleshoot such issues in heat stacks in tripleo?

Role data has been successfully generated by command:

$ openstack overcloud roles generate -o /var/workdir/tripleo-environment/tripleo-heat-templates/custom_roles_data.yaml Controller Compute

and then used to generate heat templates:

/var/workdir/tripleo-heat-templates-upstream-wallaby/tools/process-templates.py \ -p /var/workdir/tripleo-heat-templates-upstream-wallaby \ -r /var/workdir/tripleo-environment/tripleo-heat-templates/custom_roles_data.yaml \ -n /var/workdir/tripleo-environment/tripleo-heat-templates/custom_network_data.yaml \ -o /var/workdir/generated-tripleo-heat-templates \ --safe
