Horizon requires esp. keystone to work; the same applies to nova, and probably also to glance. Sorry.

I understand your response, I just only need to install the keystone for horizon.

If you are up for making some minor modifications to horizon, you can make it work without nova. First update your default panel to the swift panel in local_settings.py. Then modify all the panels in the dashboards that pertain to anything other than identity or swift panel.py not to register.. Then you have an identity and swift only horizon.

Can you explain in detail?

Here are the steps I would do.

Most of this can be done by changing openstack_dashboard/dashboard/projects/dashboard.py

This is where all of the panels are registered in the projects dashboard. Remove every panel group
except ObjectStorePanels from the panels list in the Project class.
Change default_panel in the Project class to be "object_store" rather than "overview"

You can do a similar change in the admin dashboard in openstack_dashboard/dashboard/admin/dashboard.py
In this case keep only the IdentityPanels in the panels list and change the default_panel to be one of the panels in the
IdentityPanels list.

Hope that helps.

Is that mandatory to have overview and instances in panel list in dashboard.py. other panels images, volumes etc are removed without any problem.I'm getting internal server error if I remove instances and overview from the panel.
 I want to get only object store in my horizon dashboard.

I think I might be having the same problem. The problem I am having is that I don't know what connection is being refused.

What I would like to do is either run the pdb debugger or else add a print statement in adapters.py to isolate the problem further, but I'm not sure exactly what the code is doing, and where would the output of the print statement go?

Thank you

Jeff, I'm not really sure, if your issue is solved by not using keystone, nova, etc. like the original poster said.

In your case, I'd check if neutron is running and reachable

The Nova client is failing so it looks like it's Nova that can't be reached. Check that the service is up and running, firewall ports open etc so that the Horizon machine can communicate with the nova server.
