vRealize Automation 7 – Creating Business Groups Automatically

In the blog post were are going to automatically create Business Groups in vRealize Automation 7.X. This can be handy when a customer has a lot of Business Groups and adds additional Business Groups overtime. So it was time to write a little bit of code that makes my life easier.

I wrote it in the first place for using it in my lab environment to set up vRealize Automation 7.X quickly for testing deployments and validating use cases.

Advantages of orchestrating this task:

  • Quicker
  • Consistent
  • History and settings are recorded in vRealize Orchestrator (vRO)

Environment

My environment where I am testing this vRO workflow is my Home Lab. At home, I have a Lab environment for testing and developing stuff. The only products you need for this workflow are:

  • vRealize Automation 7.6 in short vRA.
  • vRealize Orchestrator 7.6 in short vRO.

Note: The vRealize Automation endpoint must be registered to make it work.

vRealize Orchestrator Code

Here is all the information you need for creating the vRealize Orchestrator workflow:

  • Workflow Name: vRA 7.X – Create Business Group
  • Version: 1.0
  • Description: Creating a vRealize Automation 7.X Business Group in an automated way.
  • Inputs:
    • host (vCACCAFE:VCACHost)
    • name (string)
    • adname (string)
  • Outputs:
    • None
  • Presentation:
    • See the screenshots below.

Here is the vRealize Orchestrator code in the Scriptable Task:

// Variables
var domain = "company.local";
var mailDomain = "company.com";

// Input validation
if (!domain) {
	throw "Defined variable 'domain' cannot be null";
}
if (!mailDomain) {
	throw "Defined variable 'mailDomain' cannot be null";
}
if (!host) {
	throw "Input variable 'host' cannot be null";
}
if (!name) {
	throw "Input variable 'name ' cannot be null";
}
if (!adname) {
	throw "Input variable 'adname' cannot be null";
}

// Construct Group Object
var group = new vCACCAFEBusinessGroup();
	group.setName("BG-" + name);
	group.setDescription("vRA Business Group: BG-" + name);
	group.setActiveDirectoryContainer("");
	group.setAdministratorEmail("vra-admin" + "@" + mailDomain);
	group.setAdministrators(["vra-admin@vsphere.local", "vra_" + adname + "@" + domain]);
	group.setSupport(["vra-admin@vsphere.local", "vra_" + adname + "@" + domain]);
	group.setUsers(["vra_" + adname + "@" + domain]);

// Create the group; return the ID of the group.
var service = host.createInfrastructureClient().getInfrastructureBusinessGroupsService();
var id = service.create(group);

// Get the SubTenant entity from vRA
group = vCACCAFEEntitiesFinder.findSubtenants(host , "BG-" + name)[0];

// Add custom property to Business Group
vCACCAFESubtenantHelper.addCustomProperty(group, "Company.BusinessGroup", name, false, false);

// Create update client and save the local entity to the vRA entity
var service = host.createAuthenticationClient().getAuthenticationSubtenantService();
	service.updateSubtenant(group.getTenant(), group);

Screenshots

Here are some screenshot(s) of the Workflow configuration that helps you set up the workflow as I have done!

Wrap-up

This is a vRealize Orchestrator workflow example that I use in my home lab. It creates vRealize Automation Business Groups to improve consistency and speed.

Keep in mind: Every lab and customer is different. In this workflow I use for example the prefix BG- for Business Groups. What I am trying to say is modify it in a way that is bested suited for your environment.

PowerCLI Datastore Selection without Storage DRS (SDRS)

When deploying some virtual machines in a test environment I ran into the following problem. In most cases, I make use of a VMware vCenter Storage DRS cluster, in this case when deploying a virtual machine the best-suited datastore is selected for the virtual machines. The only problem is not all customers are entitled to use Storage DRS, because Storage DRS requires a vSphere Enterprise Plus license.

So I needed to create a workaround to select a datastore with enough space. The default PowerCLI behavior is selecting the first datastore detected on a alphabetic order.

So when you are deploying let’s say twenty virtual machines all those virtual machines will be put on the first datastore, so that isn’t going to work well in most cases.



PowerCLI Code

To solve the problem I created the following PowerCLI code. The code selects a cluster and lists all the datastore available. The datastore with the most space available is selected for the virtual machine that is being deployed.

In the PowerCLI code, I just create a very simple virtual machine but you probably get the point. The magic is the $DS line that selects the datastore.

Requirements:

The PowerShell code is tested with the following VMware software components on Microsoft Windows:

  • PowerCLI 6.5 Update 1
  • VMware vCenter Server 6.0
### Variables
$CLUSTER = "Production"       # A Cluster Name
$FOLDER = "Deployed VMs"      # A Virtual Machine folder name located in the vCenter inventory

### Select datastores available and sort them on free space (select the one with most space free)
$DS = Get-Cluster -Name $CLUSTER | Get-Datastore | Select Name, FreeSpaceGB | Sort-Object FreeSpaceGB -Descending | Select -first 1

### Create a virtual machine called VM01
New-VM -Name VM01 -ResourcePool $CLUSTER -Datastore $DS.Name -Location $FOLDER -MemoryGB 1 -CD -DiskGB 5
