AKS ErrImagePull and ImagePullBackOff on AKS after a year

Hi all, I’ve deployed me an AKS - Azure Kubernetes Service environment that I use in my Azure training class deliveries almost every week (yes, every AZ-course touches on AKS and Containers…) The Problem My AKS environment was running fine all this time (a bit over a year), allowing me to rely on existing deployed Kubernetes services, as well as building new services as a live demo. Until this morning, where all of a sudden, my own services didn’t start at all, but the kube-system services did.

AzCopy failing in Azure Devops with error ServiceCode=AuthorizationPermissionMismatch

Hi all, This is one of the nail biting challenges of our industry, failing in running a straight-forward task. Especially when it is failing… What happened? I was creating a pipeline in Azure DevOps to deploy an ARM template for VM setups with VM Extensions. To prep this deployment, the artifacts (DSC scripts) should be copied to Azure Blob Storage, in order for the Azure DevOps build agent to “find” it.

The weird case of the Visual Studio 2019 Dockerfile

Hey there, I’ve been doing quite a lot with Docker and the different Azure Container Services offerings like Azure Container Instance and Azure Kubernetes Services. As you probably know, the starting point of a containerized application is the Dockerfile. Look at this like an instruction script, which tells Docker what needs to happen, in order to grab the application source code, compile it and produce the container image. Besides the complexity of running containers by itself, I personally think writing a Dockerfile is equally difficult and complex.

Azure Back To School (with Azure DevOps)

Hey everyone, Wow, it’s September already! Where has summer been? And honestly, where has the (nice) year been? Most of you, just like myself, are probably still working from home, and I guess the same are your kids. Where September used to feel like a fresh start (remember that smell of your new school outfit, the new school equipment, fresh-sharpened pencils, the excitement of learning new things, meeting new class mates,… almost seems like I want to go back to school myself.

Terraform showing an error Panic not a collection type

Hi all, Earlier this week, I got blown away by an interesting Terraform issue. The Problem Running a deployment that ran fine for months. I initiated a new deployment using the usual “terraform init” step, which ran fine. Followed by the usual “terraform plan”, and BOOM, the following message appeared: Panic: not a collection type Since this was a new template I created, I assumed an issue with the syntax or anything similar.

DevOps for Dummies - Emily Freeman - Review

Hey, As some of you know me for years already, you also know I’m rather bad in coding (although I’m learning Blazor since a few weeks, but more on that journey in future posts…), and always “got scared” about DevOps. Especially the Dev part in the word 😊. I still remember being in Bangalore, India early 2016 to deliver an Azure workshop to Microsoft GSI Partners (Wipro, Tech Mahindra, Accenture,…) as a freelance trainer together with Microsoft AzureCAT engineers.
