Getting 'cassandra_seeds' is undefined" ERROR

[fclaudio...@gmail.com]

Hello guys,

I'm always getting this error while following this guide - https://github.com/Juniper/contrail-ansible-deployer/wiki/Contrail-with-Kolla-Ocata -, the exact error is:

fatal: [192.168.1.127]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'cassandra_seeds' is undefined"}

could any of you point on the right direction?

Thank you all in advance

Had the same issue - did you explicitly defined the roles? If not explicitly define the roles (even in a single node setup!) in config/instances.yaml - this worked for me to solve the issue.
