I am very new to open stack, i have installed open stack with one compute node, one controller . Now i want explore all commands in open stack.

For example list all compute nodes $ nova-manage service list

I got some doubts. 1 how can i see resources available ( exported by compute node ) in controller ? 2 How a compute node can export resource for a controller ? ( cpus, memory etc)

Edit : I am using icehouse

Give me some links to learn about openstack commands.. Thanks for your valuable timed..
