Using Rancher Desktop as Docker Desktop replacement on macOS

Last year I wrote a blog post about running Podman on macOS with Multipass as a Docker Desktop replacement. -> https://www.danielstechblog.io/running-podman-on-macos-with-multipass/ Back at that time I had looked also into Podman Machine and Rancher Desktop. Podman Machine was out very quickly without support for host volume mounts. Rancher Desktop instead was promising but the host volume Read more [...]

Using Conftest for Azure Policy for Kubernetes

Conftest is a tool that lets you write tests against structure data like Kubernetes templates. -> https://www.conftest.dev/ So, why should you use Conftest when you already established your policies with Azure Policy for Kubernetes? As Azure Policy for Kubernetes uses Gatekeeper the OPA implementation for Kubernetes under the hood it uses Gatekeeper constraint templates written in Rego. Read more [...]

Local Kubernetes setup with KinD on Podman

In one of my last blog posts I walked you through the setup how to run Podman on macOS with Multipass as Docker for Desktop alternative. -> https://www.danielstechblog.io/running-podman-on-macos-with-multipass/ Today I briefly show you the local Kubernetes setup with KinD on Podman. Even the Podman support of KinD is in an experimental state it runs stable enough for the daily usage. The Read more [...]

Cloud Native Club – Kubernetes Policies

Last week I had the pleasure of being the guest of the fifth episode of the Cloud Native Club run by my former colleague Robin-Manuel Thiel. We talked about the topic Kubernetes policies covering the Open Policy Agent, Gatekeeper and Azure Policy for Kubernetes. The Cloud Native Club format is in German and hence no English version of the recording is available. -> Folge 5: Kubernetes Policies Read more [...]

Evaluating Gatekeeper policies with the Rego Playground

Writing and evaluating Gatekeeper policies can be hard sometimes. Especially the testing part of a newly created policy. There are different approaches to tackle this like having a dedicated test Kubernetes cluster for it. An alternative we used was a script starting a single node KinD cluster on Docker for Mac and installing Gatekeeper onto it. The advantage of this approach you see how the Read more [...]

Azure Policy for Azure Kubernetes Service

In June I already covered Azure Policy for Kubernetes in a blog post. -> https://www.danielstechblog.io/using-azure-policy-for-kubernetes/ Back then Azure Policy for AKS was in public preview. At this year’s Microsoft Ignite Azure Policy for AKS went GA. -> https://azure.microsoft.com/en-us/updates/ga-policy-addon-for-azure-kubernetes-service/ There have been some significant changes Read more [...]

Running Istio on KinD – Kubernetes in Docker

In my last blog post I have shown you my local Kubernetes setup with KinD. I mentioned also Istio and today we walk through the configuration to get it running on Kubernetes in Docker. As prerequisite I recommend reading my previous blog post before you continue with this one. -> https://www.danielstechblog.io/local-kubernetes-setup-with-kind/ I made a configuration decision for KinD Read more [...]
