Overview

Represents a collection of cloud servers within a single region.

There’s currently no methods that relate to the entire collection, this is primarily used to retrieve a single Raca::Server object.

You probably don’t want to instantiate this directly, see Raca::Account#servers

Instance Method Details

#create(server_name, flavor_name, image_name, files = {}) ⇒ Object

create a new server on Rackspace.

server_name is a free text name you want to assign the server.

flavor_name is a string that describes the amount of RAM. If you enter an invalid option a list of valid options will be raised.

image_name is a string that describes the OS image to use. If you enter an invalid option a list of valid options will be raised. I suggest starting with ‘Ubuntu 10.04 LTS’

files is an optional Hash of path to blobs. Use it to place a file on the disk of the new server.

Use it like this:

server.create("my-server", 512, "Ubuntu 10.04 LTS", "/root/.ssh/authorised_keys" => File.read("/foo"))
