Pfew, it’s odd to admit that it has been a while since I’ve posted about Rancher. Though today is as good a day as any to pick up that thread… So today we’ll go through give or take the same objective as in the past, where we’ll notice that the integration has improved significantly with the arrival of AKS! Let’s get today’s post underway and deploy AKS from our Rancher control plane.
Before the below started, I already had the following things ready ;

Last week I did a post about how to integrate Compiled Azure Functions working with VSTS… In the closing thoughts I made a statement about my observation that compiled functions had a performance improvement.
Here I should have known Nills would challenge me on that… 😉

A few weeks ago the Azure Firewall went into public preview. Today’s post will be around taking it for a spin in a hub & spoke deployment.
First off, what will the architecture of our deployment look like?
- A central hub, where we’ll deploy the Azure Firewall. This will consist of the address space 172.16.0.0/12.
- Two spokes, each with their own address space (10.[1/2].0.0/16) where a UDR will send all traffic to the Azure Firewall (172.16.254.4).
- In each VNET, we’ll deploy a “SUBNET000” in which we’ll setup a vm to do our basic connectivity testing.
- Each spoke is connected with a bidirectional VNET peering with the spokes. Both spokes can only talk to each other over the HUB.
- The Azure firewall will be configured to allow traffic within the 10.0.0.0/8 range.

A question that pops up occasionally is how to setup your Azure Functions DevOps flow when you’re using C# underneath. Today’s post will be a brief one to run you through this process. If you should prefer a video on this… That exists too! Curtosiy of the app service product group.
Let’s take a look at the build process. We have (at least, as this flow did not do any testing => “Shame on me!”) three steps in the build process ;
- Restore the nuget packages
- Build the solution (and create a single zip file)
- Publish the artifact
So let’s take a look at one of my own builds… First I kick off with installing NuGet on my build agent (should it not already be present).

Today’s post will be on how I see the smoothest way to do prototyping & hobby projects in regards to IoT. What is my main principle in deciding this? I only want to spend time on “business logic” and not waste time on the nuts & bolts of the engine.
So what’s the architecture we’ll be using for this?
- Device : Particle Photon + Grove Expansion Board + Grove Sensors (Temperature & Air Quality )
- Particle Platform : Used for the development
- Azure IoT Hub : Basically a 1:1 link with Particle, which will take over once we go to a production grade setup.
- Azure Stream Analytics : Streaming the ingest data from our IoT Hub towards our various landing zones.
- Azure CosmosDB : For storing the data we’ll use in our reports.
- Azure Storage Account : Cheap storage where we keep all the data we collected, and which we could use for our analytics.
- PowerBI : The make nice reports of the data we collected. 😉
Now let’s delve into these parts one by one!

Today we’ll do a deep-dive into how you can log into an Azure Linux VM with Azure Active Directory (AAD). In essence, we’ll go through the following documentation flow, and then take a look how that looks under the hood.
Part one : “Creation”
The part on creating & integrating the VM is VERY straightforward…
- Create a resource group
- Create a Linux virtual machine
- Add the “Azure AD login VM”-extension
And that’s it! Really, that’s it…

Did you know I’m a huge fan of the Microsoft / Azure docs? Did you also know that the docs websites are powered by GitHub repositories? Let that one sink in… So you can leverage the same way you collaborate on code, work on publishing documentation?!? How awesome is that!
After a bit of looking around, it appears DocFX is actually powered to do this. I don’t know if this is the tool used behind the docs website. Though there seem to be a lot of similarities. Anyhow, today’s post will be a quick walkthrough on how to setup DocFX with VSTS to publish your GitHub driven repo to an Azure Web App.
So what will we be needing?
- GitHub repository
- VSTS Account
- Azure App Service
- A tool to do the conversion : DocFX
- Chocolatey to install DocFX
Initialize the repository
Be sure to install DocFX on your dev station to initialize the repository. This is done by running “docfx init -q” inside of your repository.
Afterwards do your typical Git magic to sync your local version with GitHub (or equivalent). Now you’ll have a dummy skeleton ready for usage, and you can now structure it to your liking! My effort is going into making docs for VMchooser.
