Comment 5 for bug 1731596

WORKAROUND:
~~~~~~~~~~~
This is because of an upstream package "td-agent" which is installed in the fluentd container dropped support for some configuration which the kolla playbook were using.

Please use the following value in the "kolla_globals" section of the cluster.json as a workaround until we fix the configuration to be compatible with the new version of "td-agent":

...
"kolla_globals": {
...
...
   "fluentd_image_full": "kolla/ubuntu-binary-fluentd:4.0.0"
...
...
}

NOTE: You will need internet access on the open stack nodes for this workaround to work.
