Created attachment 1593774 [details] Standalone deployment errors Description of problem: During one of the last few tasks of Step 5 of the deployment, it fails because Ansible cannot find a Python interpreter to use. Python is available at /usr/bin/python2, /urs/bin/python3, and /usr/libexec/platform-python. No package provide /usr/bin/python. I had to manually symlink /usr/bin/python3 to /usr/bin/python to get the installation to finish. Version-Release number of selected component (if applicable): RHOSP 15 Beta, RHEL 8.0, Ansible 2.8.2 How reproducible: 100% Steps to Reproduce: 1. Follow the RHOSP 15 Beta Quickstart guide to install a standalone cloud. https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/15-beta/html/quick_start_guide/index 2. Use the RHOSP 15 Beta container registry ``` --- parameter_defaults: ContainerImagePrepare: - set: namespace: registry.redhat.io/rhosp-beta tag: 15.0 ``` Actual results: Ansible complains with this error: """ The following modules failed to execute: setup\\\\\\\\n setup: The module failed to execute correctly, you probably need to set the interpreter. """ Expected results: Deployment successful! Additional info: Ansible 2.8 *should* have automatically detected and found a Python interpreter on RHEL 8.

The standalone post configuration uses /usr/bin/python as the Ansible interpreter for a single task that creates a symlink. https://github.com/openstack/tripleo-heat-templates/blob/577640a9c9659bb1d5b393e9bd616ef4b32b6f12/extraconfig/post_deploy/standalone_post.yaml#L31 https://github.com/openstack/tripleo-heat-templates/blob/577640a9c9659bb1d5b393e9bd616ef4b32b6f12/extraconfig/post_deploy/standalone_post.yaml#L40 For a normal Undercloud, that symlink is created by a single command via a shell script. https://github.com/openstack/tripleo-heat-templates/blob/577640a9c9659bb1d5b393e9bd616ef4b32b6f12/extraconfig/post_deploy/undercloud_post.sh#L4
In the undercloud[0] we actually set PythonInterpreter to sys.excutable. I think this is an issue with the rhel8 bits where we need to document that this be set for the undercloud https://opendev.org/openstack/python-tripleoclient/src/branch/master/tripleoclient/v1/undercloud_config.py#L393
