undercloud installation fails if rsyslog is not installed

[Alex Schultz]

Description of problem:

After a fresh install of RHEL 8.0, attempted an undercloud install. It failed due to missing rsyslog:

[stack@undercloud undercloud-ansible-54348tim]$ cat ansible-errors.json
{"hardprov-dl360-g9-01": [["Check if rsyslog exists", {"msg": "non-zero return code", "cmd": "systemctl is-active rsyslog", "stdout": "inactive", "stderr": "", "rc": 3, "start": "2019-10-02 01:52:11.855265", "end": "2019-10-02 01:52:11.862984", "delta": "0:00:00.007719", "changed": true, "invocation": {"module_args": {"_raw_params": "systemctl is-active rsyslog", "_uses_shell": true, "warn": true, "stdin_add_newline": true, "strip_empty_ends": true, "argv": null, "chdir": null, "executable": null, "creates": null, "removes": null, "stdin": null}}, "stdout_lines": ["inactive"], "stderr_lines": [], "_ansible_no_log": false}]]}[stack@hardprov-dl360-g9-01 undercloud-ansible-54348tim]

Can workaround this by installing rsyslog manually:
$ sudo dnf install rsyslog
$ systemctl start rsyslog.service

rsyslog appears to be required for haproxy and swift

I couldn't reproduce (OSP16 on RHEL7), with these rpms: http://ix.io/20k4
My undercloud deployed just fine. Can you please share your rpm list?

[Alex Schultz (alex-schultz)]

To reproduce ensure rsyslog is not installed prior to deploying the undercloud. The qcow2 image has it by default, but an base install from an iso may not.

    Install and start Rsyslog on the Undercloud & Standalone

    Create a new Rsyslog service that is deployed on the host (not in a
    container) and with Ansible.

    Make it so it's deployed by default on Undercloud & Standalone setups.
    Also move the tasks that configure rsyslogd for HAproxy & Swift to be
    executed after the host prep tasks (using deploy step tasks).
