I have attempted to install tripleo several times and keep getting errrors on centos. I used the same config on rhel and it completes normally.

TASK [Restart rsyslogd service after logging conf change] *************************************************************************fatal: [ucloud]: FAILED! => {"msg": "The conditional check 'logconfig|changed' failed.

I looked in the play book and the item listed was *- name: Check if rsyslog exists register: rsyslog_config stat: path: /etc/rsyslog.d - block: - copy: content: '# Fix for https://bugs.launchpad.net/tripleo/+bug/1776180 (https://bugs.launchpad.net/tripleo/+b...)

I found the config file created in rsyslog.d but no sift.log in the containers folder. any thoughts on how to figure this out would be appriciated.
