The Luna Node Dynamic API enables you to write software to automate VM management. This page details how the API can be accessed. Visit the API tab to manage your API keys.

Overview

Each API token consists of an API ID and an API key. Both are needed for authentication of all API commands.

API actions consist of a category label, action label, and a set of parameters. For example, to start a VM, the category label is "vm", action label is "start", and a "vm_id" parameter must be set. See the full API action list.

API requests are made over HTTPS. Once the server completes processing of your request, it will return a JSON-encoded response.

Usage

We provide open source (under CC0 1.0) PHP and Python libraries for accessing the Luna Node Dynamic API. These libraries make interaction with the API easier, handling transaction from category, action, and parameters to the HTTPS request, and from the JSON-encoded response to a PHP associative array or Python dictionary. Download the libraries here.

Examples

List your virtual machines:

<?php

require_once('lndynamic.php');
$api_id = 'YOUR API ID';
$api_key = 'YOUR API KEY';
$api = new LNDynamic($api_id, $api_key);
print_r($api->request('vm', 'list'));

?>

from lndynamic import LNDynamic
api_id = 'YOUR API ID'
api_key = 'YOUR API KEY'
api = LNDynamic(api_id, api_key)
print api.request('vm', 'list')

Recreate a VM with the same IP:

<?php

require_once('lndynamic.php');
$api_id = 'YOUR API ID';
$api_key = 'YOUR API KEY';
$target_vm_name = 'myvm';
$target_image_name = 'Ubuntu 14.04 64-bit (template)';
$api = new LNDynamic($api_id, $api_key);

// find the target virtual machine ID
$vms = $api->request('vm', 'list');
$target_vm_id = false;

foreach($vms as $vm) {
	if(strcasecmp($vm['name'], $target_vm_name) === 0) {
		$target_vm_id = $vm['vm_id'];
		break;
	}
}

//find the target image ID
$images = $api->request('image', 'list');
$target_image_id = false;

foreach($images as $image) {
	if(strcasecmp($image['name'], $target_image_name) === 0) {
		$target_image_id = $image['image_id'];
		break;
	}
}

if($target_vm_id === false) {
	die('No VM found!');
}

if($target_image_id === false) {
	die('No image found!');
}

// disassociate the IP address
$info = $api->request('vm', 'info', array('vm_id' => $target_vm_id));
if(empty($info['ip'])) {
	die('VM does not have IP!');
}
$api->request('vm', 'floatingip-delete', array('vm_id' => $target_vm_id, 'keep' => 'yes'));
$api->request('vm', 'delete', array('vm_id' => $target_vm_id));
$api->request('vm', 'create', array('hostname' => $info['info']['hostname'], 'plan_id' => $info['extra']['plan_id'], 'image_id' => $target_image_id, 'ip' => $info['info']['ip']));

?>
