Kubernetes
With only a single command, you could have a fully-functional cluster running locally in seconds!
terraform
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,
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
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
kubectl
Easily and rapidly switch between kubectl namespaces.
Career
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
cloud
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
Azure Kubernetes Service
I'm going to share with you some of the best resources out there for learning Kubernetes. Take a look!
Kubernetes
A few quick and easy ways to switch contexts rapidly.
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
terraform
I admit it. There was a time, very recently, when I deployed infrastructure by going into the Azure portal and clicking some buttons. It seems so easy! But there's an associated cost. So much so that I just finished defined and deployed a new Azure Kubernetes Service cluster
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
