Hi guys,

I'm trying to install Murano the applications catalog in RDO OpenStack by following this guide :

When i try to create the murano user in the Murano Node by using this command:

openstack user create –os-username admin –os-auth-url –os-project-name admin –os-identity-api-version 3 –password ***** murano

I get this authentication error:

Failed to contact the endpoint at http://Controller-Node:35357/v3 for discovery. Fallback to using that endpoint as the base url.
Unable to establish connection to http://Controller-Node:35357/v3/users

So what can i do to make the openstack endpoint reachable for the murano node ?

Hi Badis, are you using keystone v3 or v2.0? If you source your admin_keystonerc file and issue openstack user list, do you get a response?

When you create the endpoint sourcing the file as the last step you made, you get an error or success. Can you also paste both commands with source and without source with --debug added in the command? We can see what is wrong in the request, also, this is not an issue with murano is at keystone?

Note that sometimes you have IP address and sometimes you have Hostnames specified.
The initial AUTH URL uses the IP address: Which seems to succeed. It then should get the identity endpoint out of the service catalog, and that seems to be using the hostname:


Apache or HA Proxy is not responding to this, probably as it needs to be in the vhost section of the Keystone Config file. Either change the endpoint to use the IP address, or, even better, make Apache respond to requests for the Hostname.
