#create_keypair(options) ⇒ Object

Create a new keypair for use with launching servers. Raises a OpenStack::Exception::NotImplemented if os-keypairs extension is not implemented (or not advertised) by the OpenStack provider.

The ‘name’ parameter MUST be supplied, otherwise a OpenStack::Exception::MissingArgument will be raised.

Optionally requests can specify a ‘public_key’ parameter, with the full public ssh key (String) to be used to create the keypair (i.e. import a existing key).

Returns a hash with details of the new key; the :private_key attribute must be saved must be saved by caller (not retrievable thereafter). NOTE: when the optional :public_key parameter is given, the response will obviously NOT contain the :private_key attribute.

>> os.create_keypair(:name=>“test_key”)

#create_server(options) ⇒ Object

Creates a new server instance on OpenStack Compute

The argument is a hash of options. The keys :name, :flavorRef, and :imageRef are required; :metadata, :security_groups, :key_name and :personality are optional.

:flavorRef and :imageRef are href strings identifying a particular server flavor and image to use when building the server. The :imageRef can either be a stock image, or one of your own created with the server.create_image method.

The :metadata argument should be a hash of key/value pairs. This metadata will be applied to the server at the OpenStack Compute API level.

The “Personality” option allows you to include up to five files, # of 10Kb or less in size, that will be placed on the created server. For :personality, pass a hash of the form => ‘server_path’. The file located at local_path will be base64-encoded and placed at the location identified by server_path on the new server.

Returns a OpenStack::Compute::Server object. The root password is available in the adminPass instance method.

>> server = cs.create_server(
     :name        => 'NewServer',
     :imageRef    => '3',
     :flavorRef   => '1',
     :metadata    => {'Racker' => 'Fanatical'},

#limits ⇒ Object

Returns the current state of the programatic API limits. Each account has certain limits on the number of resources allowed in the account, and a rate of API operations.

The operation returns a hash. The :absolute hash key reveals the account resource limits, including the maxmimum amount of total RAM that can be allocated (combined among all servers), the maximum members of an IP group, and the maximum number of IP groups that can be created.

The :rate hash key returns an array of hashes indicating the limits on the number of operations that can be performed in a given amount of time. An entry in this array looks like:

{:regex=>"^/servers", :value=>50, :verb=>"POST", :remaining=>50, :unit=>"DAY", :resetTime=>1272399820, :URI=>"/servers*"}

This indicates that you can only run 50 POST operations against URLs in the /servers URI space per day, we have not run any operations today (50 remaining), and gives the Unix time that the limits reset.

Another example is:

{:regex=>".*", :value=>10, :verb=>"PUT", :remaining=>10, :unit=>"MINUTE", :resetTime=>1272399820, :URI=>"*"}

This says that you can run 10 PUT operations on all possible URLs per minute, and also gives the number remaining and the time that the limit resets.

Use this information as you’re building your applications to put in relevant pauses if you approach your API limitations.
