Deploying a Kubernetes Cluster on Azure Stack fails

I just finished updating my Azure Stack ASDK to the latest 1901 version. Before the upgrade I was messing around with the Kubernetes cluster offering, and I wanted to get that added back to my ASDK now that I’ve performed the update. I rushed through the process, and of course got an error. And that error was not very helpful. Just in case you’re like me, and missed a step in the setup for K8s on Azure Stack, here are the various error messages and the solution.

The TL;DR? Add the Service Principal you created for K8s as a Contributor on the subscription the cluster will be running in.

You’re welcome.

Some helper scripts for Azure Stack Development Kit

Not too long ago, I got a DL380 Gen10 from HPE to deploy the Azure Stack Development Kit. I had been limping along with a couple Frankstein systems running on Gen8 and Gen9 hardware. They had slow disks, not enough storage, and not enough RAM. This new beast has 384GB of RAM, 20 cores, and SSDs for the OS disk. Basically it’s awesome, and I am a very happy nerd. Since the early days of the ASDK, when it was just a little Technical Preview, there have appeared a growing library of scripts to help with the deployment of the ASDK. Since I am deploying the latest version today (1811), I thought it might be a good idea to share some helper scripts I put together to make the process a bit faster.

Hybrid Cloud is On Target for 2019

If you were going to build a brand new application today, your approach would probably be fundamentally different than five or ten years ago. And I do mean fundamentally, as in the fundaments of the architecture would be different. In the last ten years we have moved rapidly from traditional three-tier applications to 12-factor apps using microservices, and now things are shifting again to serverless. That’s all well and good for any business looking to build a new application, but what about organizations that have traditional applications? I’ve also heard them called legacy or heritage applications. These applications are deeply ingrained in the business and are often what is actually generating the bulk of a company’s revenue. The company cannot survive without these applications, and modernizing them will be costly and fraught with risk. Due to the inherent risk, most companies opt to either keep these applications running on-premises or move them as-is to the public cloud, aka life and shift. That’s the reality we’re living with today, but tomorrow is knocking on the door and promising hybrid cloud to fix all this. What’s the reality and what’s the hype? And what is the most likely journey for most companies?

AWS Outposts and Azure Stack

This week was AWS re:Invent, and I watched the keynote live-on Wednesday.

The three. hour. keynote.

During which Andy Jassy announced new features at a pace that is frankly astounding. Three hours should be too long for a keynote, and if I wasn’t watching from the comfort of my office, it would have been. Not only did the announcements keep unfolding for the full 270 minutes, but some didn’t even make it into the keynote. Running a three hour keynote is tough, creating enough new services and features to overflow a three hour keynote is amazing. My hat goes off to the engineering teams at AWS. It is truly staggering what you manage to accomplish each year.

AzureStack on Azure – Part 3

In the last two parts we deployed an Azure Stack Development Kit on an Azure VM and got it registered with Azure. Then we created an Offer and Plan for the default user and started the download of marketplace items for use on Azure Stack. Now that those items have completed their download, we can move on to the process of installing the Resource Providers (RPs) for Microsoft SQL Server (MSSQL), MySQL Server, and the App Service. In this post I will cover the process and scripts you can use to get the MSSQL and MySQL RPs running. The App Service will be a separate post, due to the additional complexity involved.
