Strange YAML syntax issue with openshift inventory file

[abisek9186]

[k5user@master1 openshift-ansible]$ ansible-playbook /etc/ansible/inventory_to_install_openshift_logging playbooks/byo/openshift-cluster/openshift-logging.yml
ERROR! Syntax Error while loading YAML.

The error appears to have been in '/etc/ansible/inventory_to_install_openshift_logging': line 4, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

# Comment lb out if your load balancer is pre-configured.

My inventory file is below

# Create an OSEv3 group that contains the master, nodes, etcd, and lb groups.

@abisek9186 Looks like a missing [OSEv3:vars] tag above variables.

Oh..gosh..my bad. I was missing -i in ansible-playbook command.
