Supernova instead of Nova?

We installed Supernova on Sierra, which is a very useful tool for OpenStack. If you say yes to any of the following questions, you should try Supernova.

• Do you have multiple projects(tenants)?
• Do you have another OpenStack to run your instances?

So here's how to use Supernova on Sierra.

* Before you try Supernova on FutureGird, you have to have your FutureGrid account and should know how to use OpenStack. Here's the link of our OpenStack Tutorial -> http://manual.futuregrid.org/openstackgrizzly.html

Login to Sierra and load Supernova.

ssh username@sierra.futuregrid.org
module load supernova

Check your novarc file and create your ~/.supernova file like below. In this example, my account(user1) is a member of fg123 and fg456.

[fg123]
OS_AUTH_URL=https://s77r.idp.sdsc.futuregrid.org:5000/v2.0
OS_CACERT=/etc/futuregrid/openstack/sierra/cacert.pem
OS_PASSWORD=***************
OS_TENANT_NAME=fg123
OS_USERNAME=user1

[fg456]
OS_AUTH_URL=https://s77r.idp.sdsc.futuregrid.org:5000/v2.0
OS_CACERT=/etc/futuregrid/openstack/sierra/cacert.pem
OS_PASSWORD=***************
OS_TENANT_NAME=fg456
OS_USERNAME=user1

Don't forget to change the permission to make it unreadable to anyone else.

chmod 600 ~/.supernova

Now, you should be able to check your tenant list.

supernova --list

-- fg123 --------------------------------------------------------------------
  OS_AUTH_URL          : https://s77r.idp.sdsc.futuregrid.org:5000/v2.0
  OS_CACERT            : /etc/futuregrid/openstack/sierra/cacert.pem
  OS_PASSWORD          : ***************
  OS_TENANT_NAME       : fg123
  OS_USERNAME          : user1
-- fg456 --------------------------------------------------------------------
  OS_AUTH_URL          : https://s77r.idp.sdsc.futuregrid.org:5000/v2.0
  OS_CACERT            : /etc/futuregrid/openstack/sierra/cacert.pem
  OS_PASSWORD          : ***************
  OS_TENANT_NAME       : fg456
  OS_USERNAME          : user1

The usage is the same as Nova Client. You just need to replace "nova" to "supernova <tenantname>". Here's how to boot an instance on each tenant.

supernova fg123 boot --image futuregrid/ubuntu-12.04 --flavor m1.small --key-name mykey fg123vm001
supernova fg456 boot --image futuregrid/ubuntu-12.04 --flavor m1.small --key-name mykey fg456vm002
supernova fg123 list
supernova fg456 list

Very easy and very useful, isn't it?

In my work, I have multiple tenants and multiple OpenStack sets to work with, so Supernova is very very very helpful. I hope it makes your work easier, too!


Thanks,
