As you know from the previous post, my first book will be published soon. However, not everything could be in one book, so I will also add articles that you can read here.
At first glance, something goes into which vRA was created. Automatic machine provisioning with a specific application.
My environment is as follows:
vCenter with two templates Windows and Linux
two customization files for Windows and Linux
One vRA 8 with vCenter Endpoint and one Project.
At the beginning I created a blueprint which contains one vsphere machine and one network also with vsphere. Blueprint looks in that way
As you already know perfectly in Cloud Assembly, we have Infrastructure as a code which manifests itself in the possibility of creating blueprints using YAML code
So the code looks like this
formatVersion: 1
inputs: {}
resources:
Cloud_vSphere_Machine_1:
type: Cloud.vSphere.Machine
properties:
image: ''
cpuCount: 1
totalMemoryMB: 1024
networks:
- network: '${resource.Cloud_vSphere_Network_1.id}'
Cloud_vSphere_Network_1:
type: Cloud.vSphere.Network
properties:
networkType: existing
As this is a standard and simple blueprint can stop here but I think that what we will have at the end will be better.
So basically I wanna customize this as much as I can, that I’ve change CPU and memory as an Input properties and now we can setup this in request phase.
CPU:
type: integer
default: 1
title: Number of CPU
description: Number of CPU
Mem:
type: integer
default: 1024
title: Mem Size
description: Mem Size
However, the CPU and memory are not everything because we imagine the situation that the client wants to have a choice between Windows and Linux, so we could create two patters and assign an appropriate Image to each of them, but I decided to set the system selection as an option and of course why we need a clean system like we can customize it from vCenter
In my environment I have two images and two customizations so the user can choose himself
image_name:
type: string
enum:
- Win
- Lin
default: Win
title: Image Name
description: Image Name
custom_spec:
type: string
enum:
- Win-Stat-192
- Lin-Stat-192
default: Win-Stat-192
title: Customization Name
description: Customization Name
The next element is the network, we should also give the user a choice, that’s why I used the same maneuver and in the list of choices, it passes values from two network profiles
net_name:
type: string
enum:
- vra
- lab
default: vra
title: Network Name
description: Network Name
the last element that is in the patter is middleware, in order to show the functionality I chose the web server as true or false
web_server:
type: boolean
title: Web Server
description: Web Server
default: false
At the very end I transferred all the elements to the Virtual Machine and to the network settings, and full YAML looks like this
formatVersion: 1
inputs:
image_name:
type: string
enum:
- Win
- Lin
default: Win
title: Image Name
description: Image Name
custom_spec:
type: string
enum:
- Win-Stat-192
- Lin-Stat-192
default: Win-Stat-192
title: Customization Name
description: Customization Name
CPU:
type: integer
default: 1
title: Number of CPU
description: Number of CPU
Mem:
type: integer
default: 1024
title: Mem Size
description: Mem Size
net_name:
type: string
enum:
- vra
- lab
default: vra
title: Network Name
description: Network Name
web_server:
type: boolean
title: Web Server
description: Web Server
default: false
resources:
vSphere_Machine_1:
type: Cloud.vSphere.Machine
properties:
image: '${input.image_name}'
cpuCount: '${input.CPU}'
totalMemoryMB: '${input.Mem}'
networks:
- network: '${resource.vSphere_Network_1.id}'
name: '${input.image_name}VM'
customizationSpec: '${input.custom_spec}'
web_server: '${input.web_server}'
vSphere_Network_1:
type: Cloud.vSphere.Network
properties:
networkType: existing
constraints:
- tag: '${input.net_name}'
Diagram was not change much but here it is
As our blueprint is completed, we can pass it on to users on the Service Broker portal.
Users can, however, unknowingly choose values that do not match (e.g. Windows and customization for Linux) so I decided to limit the choice of customization only by informing what was chosen by using custom forms and the usual IF parameter.
On the broker portal in the content tab we have the opportunity to create custom forms
Our standard form looks in that way
On Customization Name I’ve marked this field as read only but visible to all
and I’ve setup a Values which depend from what user setup in Image
Now we can request our VM.
however let’s hold on. Who will install our web server? I decided to use here a solution known from earlier versions of vRa, namely workflow in vRO. So I created a subscription to call my pattern after the deposit was completed.
my workflow in vRO may not be extraordinary, but a simple solution thanks to which I achieve what is required, i.e. installed Web Server.
So on Windows we will have IIS and on Linux we will have Apache. If you wanna se my code please left comment here.
And now we can finish the topic of simple workflow and as you can see it is not so scary as it might seem and with a simple configuration we achieve our goal.
To read in the next article I hope that you will still be with me
This looks great,
could you share your code.
Apologize, I should have put more details in my request for code yesterday.
What a valuable example. I’m very interested in learning how you coded the subscription and payload portion. And how you were successful in coding the ability to select multiple templates deployments through a single catalog. I’m currently involved in a vRa 8 project an would like to work with you in more details if that’s possible. Hope to hear from you soon. Thank you
Hello what actually you wanna achive, I will be happy If I can help you
Hi Friend,
Can you plz provide the VRO code for install IIS, Apache ?
Also what will be action code when i want to install SQL DB
Nice article, I would like to see codes for IIS OR database deployment on the windows server and on the Linux server Apache.
Hi, i’d also like to know the code for installing applications. Could you send me the details?

Hi ,
have written blueprint yaml and we are using ansible for post provisioning task.. the issue is like we are able to create the vm by thru bp deplyment but it is getting stuck after i mean not acknowledging back to vra to get the ansible connection.
any lead will be appreciated.
vra 8.0
Thanks

Thank you very much in advance!
BR
it is simple script for Apache through yum for IIS it is through powershell
