Create a full-featured Kubernetes Cluster on your PC
With only a single command, you could have a fully-functional cluster running locally in seconds!
terraform
Terraform and Helm
Did you know that you can fully create a managed Kubernetes cluster in Azure using Terraform? Well you can take that one step further and also manage what's installed in your cluster using Terraform and Helm. This can be done by using the Helm provider for Terraform. Now,

Verify Node is Ready to join K8s Cluster
What happens if a node joins a cluster before it is ready? Fortunately, you'll never have to find out. For this very reason, there is a test suite maintained by the Kubernetes community called the Node Conformance Test. This set of tests will ensure that the node complies

Major Limitations of Kubernetes
The limits of Kubernetes are generally going to be difficult to hit for many organizations. But having said that, here are the major limitations of Kubernetes: * Maximum pods per node: 100 * Maximum nodes: 5,000 * Maximum pods: 150,000 * Maximum containers: 300,000

How to Keep up with the Rapid Pace of Azure
I work with Azure a lot. And as a Solutions Architect, I often find myself seeking answers to rather deep questions, refreshing my memory on old tech or concepts, or seeking new technology or solutions to solve my problems. I admit, it's extremely hard to keep up. Whatever

Azure Private Link
Have you ever created a resource in Azure (i.e. a database or storage account) and seen the option "Allow access to Azure services". You can toggle this on and allow any Azure service to talk with your resource, assuming it is authenticated. For most, that's

Choosing a Git Branching Strategy
There are several out there, and a lot of opinions to go with them. Having served in a consulting capacity for many organizations, ranging from small startups to very large enterprises, I have seen all of the major strategies. I've even seen organizations make up their own strategies

How Many Kubernetes Clusters You Should Have 🚢
At my current company, the powers that be have bought into a multi-cluster approach. I'm not saying 1 cluster per environment or region. No. I'm saying 1 non-production and 1 production cluster per system per region. Essentially, each team gets their own pair of clusters in

Visualize Azure Active Directory Role-Based Access Control for Kubernetes
Acronyms: * AAD - Azure Active Directory * AKS - Azure Kubernetes Service * RBAC - Role-based access control Recently, I implemented AAD for AKS RBAC. The documentation doesn't do a great job of visualizing what the mappings look like, so here's a quick view of how you can

Pipelines as Code - Don't Reinvent the Wheel
The term "Pipelines as Code" means that you are defining the process through which your code moves from source control, all the way to running in production. This practice is absolutely necessary if you want to build a high performing development process that allows your system to be

When to use a StatefulSet in Kubernetes
To put it simply, a StatefulSet should be used to govern one or more related pods that need to track state in some way. A StatefulSet would be what you use instead of a Deployment. StatefulSets are a particularly cool implementation detail among Kubernetes workload APIs. It works very similarly

How to Get Started with Kubernetes
When getting started with Kubernetes, I was extremely lost. I tried jumping straight into the Kubernetes documentation, but I wasn't able to make sense of it all and where to begin. It's okay if that's where you are – that's totally normal. So,

CI/CD for Kubernetes Applications (Part 1)
So you're ready to automate your application deployment to Kubernetes. You've made the right choice! Let's consider what a pipeline might look like if you are using Kubernetes manifests directly without the use of a tool such as Helm. In other words, you just
