Create custom yaml file with parameter_defaults: IronicDefaultDeployInterface: direct 2. Add to undercloud.conf entry with path those yaml file custom_env_files = /home/stack/undercloud_custom_env.yaml 3. Start openstack undercloud install Actual results: FileNotFoundError: [Errno 2] No such file or directory: 'python': 'python' Expected results: No error Additional info:
looks like it's specific to when custom_env_files are included, there is a hardcoded 'python' in tripleoclient that needs to be fixed.
Verified on openstack-tripleo-heat-templates-10.4.1-0.20190403221322.0d98720.el8ost.noarch It is not reproducible.
