Kubernetes
Explain it like I'm five: Kubernetes. Here are the big highlights that define the use case of Kubernetes.
Kubernetes
With only a single command, you could have a fully-functional cluster running locally in seconds!

How to solve 413 Request Entity Too Large in Kubernetes using NGINX Ingress.
Kubernetes
Let's say you have a pod that you want to reject all traffic to, unless the traffic is coming from a specific type of pod. In this case, an ingress Network Policy will serve your needs. Here's a quick example of what that might look like
Kubernetes
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
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

Easily and rapidly switch between kubectl namespaces.

I'm going to share with you some of the best resources out there for learning Kubernetes. Take a look!

A few quick and easy ways to switch contexts rapidly.
Kubernetes
Logically isolate and group objects inside of Kubernetes with loose coupling.
Azure Kubernetes Service
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
azure active directory
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
Azure Kubernetes Service
Did you know that Terraform can run kubectl commands? Yep! There's a provider for Kubernetes. The Kubernetes provider has a growing list of resources that you can manage via Terraform. For instance, you could declaratively and explicitly manage Kubernetes permissions via Terraform by defining roles and role bindings.
Azure Kubernetes Service
I implemented the Azure Active Directory (AAD) integration with Azure Kubernetes Service (AKS) for Role Based Access Control (RBAC) today in an existing cluster. I use Terraform to manage the cluster as well as all of the Helm installs and custom resource definitions that I apply via kubectl. The Problem
Kubernetes
This is an incredibly useful tool. If you have an application running in Kubernetes and you need to connect to you application or database, you can simply forward a port to your local machine via the kubectl port-forward command. Let's say you have a MySQL database running in
