Horizon's list of required services includes Nova, Glance and Keystone. At present no work has been done to make it run with a Swift + Keystone (only) configuration. That said, it's not impossible. The easiest route would likely be to "unregister" all of the Nova and Glance-related panels in the existing System and Project dashboards (this can be done using Horizon's "customization_module" setting, though documentation for it is minimal), and provide a custom "user_home" function that directs users to the Containers (e.g. Swift) panel upon login.

In general as long as you don't ever touch any of the panels that try to make API calls to Nova or Glance you can avoid having to run those services. Unfortunately, *a lot* of the panels *do* make calls to those services. The Swift "Containers" panel does not, though, so it can be done.

Keystone is absolutely required, though, along with proper Swift + Keystone auth integration. That part is critical.

All the best,

Subject: [Openstack] New to OpenStack - question Swift+Keystone & Horizon

Hi

I have just started to take a look at OpenStack (especially Swift, as this is what is most needed for a case I am investigating).
So far I have managed to get a Swift node up and running (all-in-one) on Ubuntu, but for some reasons I have been asked to take at look at the RedHat preview-implementation of the Folsom release.

Since Nova and the other parts not are needed, I would prefer not to install those parts... But will Horizon still be able to work - just with Swift and the underlying identity service based on keystone ?

I have tried the RedHat approach, and Keystone is up and running. I then tried to install and configure Horizon according to the RedHat instructions (and installed Swift afterwards). But whenever I log on to the Horizon interface, I get an "internal server error" page back.

Sine I don't know whether Horizon will run on such a limited setup (and I have not been able to locate information about it), I don't know whether it could be a bug in the RedHat implementation - or it simply is an unsupported setup...

Regards
Brian
