vRO: Using vRA REST API to get all vCAC VMs

Hi there !!

It’s been a very long timmmmmeee since my last post.

As usual, just a post to help in saving time. Today we’ll deal with REST API and mainly how to get information registered vCAC VMs in a huge number of pages.

When we want to query your CAFE host and obtain the number of deployments, we very often a response that does not fit on a single page.

In vRA API REST guide, VMware tell us to make as many requests as we have pages to browse. Let me show you how I do this…

var restClient = vCACCafeHost.createRestClient(endpoint);
var deploymentResourceUrl = "/consumer/resources/types/Infrastructure.Virtual/";
var parentDeploymentInfos = new Properties();
var allDeployedVm = new Array();
var deployedVmCount = 0;

function preparingRestContext(url)
{
	jsonContent = getRestResponseInJsonFormat(url)
	var responseTotalPages = jsonContent.metadata.totalPages
	return responseTotalPages
}

function getRestResponseInJsonFormat(url)
{
	var response = restClient.get(url);
	var jsonContent = response.getBodyAsJson();
	return jsonContent
}

System.log("===================================================")
System.log("**** Collecting all resources of type \"Deployment\" ***")
System.log("===================================================")

var numberOfPagesToParse = preparingRestContext(deploymentResourceUrl)
System.log("Number of page to parse : " + numberOfPagesToParse + ".")

for(i=1;i<=numberOfPagesToParse;i++)
{
	requestUrl = "/consumer/resources/types/Infrastructure.Virtual/?page=" + i;
	var jsonContent = getRestResponseInJsonFormat(requestUrl)
	
	for each (var resource in jsonContent.content)
	{
		vmEnvironment = (resource.name).substring(4,5)
		var vmDeploymentProp = new Properties();
		vmDeploymentProp.put("Name",resource.name)
		vmDeploymentProp.put("ParentLabel",resource.parentResourceRef.label)
		vmDeploymentProp.put("Owner",resource.owners[0].ref)
		vmDeploymentProp.put("Environnement",vmEnvironment)
				
		allDeployedVm.push(vmDeploymentProp);
		deployedVmCount = deployedVmCount + 1;
	}
}

System.log("")
System.log("== Collecting resources information to identify deployment environment ==")
System.log("VM deployed number : " + deployedVmCount)
