Invoking Nova commands remotely

Hi All,

I have a setup with one openstack controller with multiple compute node. In
a separate node, say monitor node, I want to invoke the nova commands on
openstack controller. Do we need to run any specific components of
openstack on this node to achieve this ?

Is there any way to invoke the nova commands such as nova-manage, nova
list.. etc remotely?

Thanks in advance.

Re: Invoking Nova commands remotely [In reply to]

"nova list" and other "nova *" commands work by making http (or https) connections to your api node. Any node that has network access to it can make calls just fine as long as you've got the right environment variables set, which include: NOVA_URL, NOVA_PROJECT_ID, NOVA_USERNAME etc.

"nova-manage" is a bit more deeply imbedded into the nova internal architecture. Setting up a novarc with ampq details and database connection details will probably allow it to work, but I wouldn't be surprised ifyou ran into some weird behavior...
