Customizing VMs with Cloud-Init

 Last post was all about creating Virtual Machines through VM Services operator provided by vSphere with Tanzu, which would give immediately freedom of choice to Developers when it comes to choose how their application might be made of; Containers, Pods, VMs, a mix of all of them .... in fact it does not matter anymore, they can build and run any of them just the same way.

Honestly, my previous post just shows how to create VMs, All the fun comes now when we can customize it during provisioning.

Guest customization is performed by the use of Cloud-Init, mainly because it became one of the most popular customization tools out there, meaning that you can leverage all that beauty you already have created.

Cloud-Init also provides dozens of modules since basic things like creating Users and Groups, Repo configuration, Packages installation, but also more advanced functions like integration with Puppet and Chef. As a start I suggest going through the examples available on their portal.

Back to my initial ConfigMap, it just had basic customization

Let's see how we can pimp this code:

First create your cloud-init file with the customization you want to make. I made a basic one, just user's creation, set it's password, install some package and run a command.

Although it's available on my git, it's far from being considered best practices, use it at your own risk !!

Once it's done, you will add it to ConfigMap under user-data section, which by the way need to be base64

just run: cat "cloud-init-file" | base64

Now just copy the code and past under the user-data... make sure it's a single line of code.

It's all set now, you can create your VMs just as I showed on the previous post.


Good customization !!!

Creating Virtual Machines with Tanzu 2/2

A few weeks ago, I started blogging about VM service, a new feature of vSphere with Tanzu update 2 which allows developers to created virtual machines with descriptor files, just the same way they do with Pods and Containers.


By that time, I wrote through the eyes of an Operator, which will setup the environment to Developers consume in a secure and control manner.


Today, let’s see how a Developer benefits from a self-service Virtual Machines consumption, enhancing their agility, delivering solutions faster to the marketing.


To start with login to supervisor cluster and make sure your context is configured to the Namespace where VM service has been configured


Documentation page provides a basic template to start with, but if you wanna test my use case, I also published it on my git.



I highlighted some points on the yaml file, those are the critical information you need to provide as follow:


imageName: it’s the template’s name which was made available to your Namespace as part of the Content Library selection:

to list all templates available run: kubectl get vmimage

Along with the templates available for VM Service it also lists templates for Tanzu Kubernetes Cluster (if it has been configured to your Namespace);



className: is that kind of t-shirt size profile which dictates the resources your VM will get.

To list the classes available run: kubectl get virtualmachineclassbindings


The name might not be the most intuitive thing in the world, describe the class to get detailed information about the resources allocated, running kubectl describe virtualmachineclassbindings “class_name”



storageClass: That’s the name of the storage policy where the disks of your VM will be created at:

To list the storage policies available to you run: kubectl get resourcequotas

The first part is your storage policy name

networkName: that’s the network name attached to your VM, but it’s ONLY REQUIRED if you are using vSphere Distributed Switch, otherwise you can remove this specification.

To get the networks available to you run: kubectl get network



In case you get a message like: Error from server (Forbidden): is forbidden: User "sso:user@domain" cannot list resource "networks" in API group "" in the namespace "name" it means your Namespace is configured with NSX-T (see topic bellow)


networkType: it’s the solution providing network services to  your Supervisor Cluster; it can be vsphere-distributed or nsx-t

For a developer it’s not something they would know or care about to be honest, to make sure the result you got querying the network is valid you can just describe the network, running kubectl describe network "net_name"



That’s all you need to create your VM.


Well, there’s nothing fancy about creating VMs if we cannot customize it right ? 


Customization of VMs like installing packages, creating files, adjusting settings is done through the use of ConfigMaps, but this topic deserves its own blog post. (check it out)


For now, as part of my deployment I also create a ConfigMap which just configures hostname and set up the default password (which will be required to change upon first login). 

Just create the VM as you would normally do with any Kubernetes object



In a few minutes the VM will be available, run kubectl get vm


Also, the VM will be on vCenter inventory under the Developer's Namespace, just as any other VM.



That's what I call Developers freedom !!
