Overview

Class for accessing the Lunanode API.

The class is instantiated by either passing it a JSON file containing the keys `api_id` and `api_key`, or specifying the ID and key directly:

api = Lunanode::API.new("credentials_file.json")
api = Lunanode::API.new(api_id: "ABCDEFG", api_key: "HIJKLMNOP")

Once instantiated, action methods follow the example:

api.vm_list # no parameters
api.vm_info(vm_id: "My-VM-ID") # required parameters
api.image_list(region: "Toronto") # optional parameters

Required and optional arguments are specified in the method definitions, but can can be queried via API.params_for. They follow the API specification atwiki.lunanode.com/index.php/API

Constructor Details

#initialize(credentials_file) ⇒ API #initialize(api_id: , api_key: ) ⇒ API

Instantiate an API object

Overloads:

  • #initialize(credentials_file) ⇒ API

    Instantiate an API object from a credentials file.

    Parameters:

    • credentials_file (String, File) —

      a JSON credentials file (which contains the keys `api_id` and `api_key`)

    Raises:

    • (JSON::ParserError) —

      if the JSON file could not be read properly.

    • (KeyError) —

      if any required key could not be found.

  • #initialize(api_id: , api_key: ) ⇒ API

    Instantiate an API object from an API ID and API Key.

    Parameters:

    • api_id (String) (defaults to: ) —

      A LunaNode API ID

    • api_key (String) (defaults to: ) —

      A LunaNode API Key

    Raises:

    • (KeyError) —

      if any required key could not be found.

  • :req => Required positional argument

  • :opt => Optional positional argument

  • :rest => Arbitrary additional positional arguments

Parameters:

  • method_name (#to_sym) —
