Check your yaml files with kubeval and GitHub Actions
In the previous post, I deployed AKS, Nginx, External DNS, Helm Operator and Flux with a YAML pipeline in Azure DevOps. Flux got linked to a git repo that contains a bunch of yaml files that deploy applications to the cluster but also configures Azure Monitor. Flux essentially synchronizes your cluster with the configuration in…
Deploy AKS with Nginx, External DNS, Helm Operator and Flux
A while ago, I blogged about an Azure YAML pipeline to deploy AKS together with Traefik. As a variation on that theme, this post talks about deploying AKS together with Nginx, External DNS, a Helm Operator and Flux CD. I blogged about Flux before if you want to know what it does. I added the…
Front Door with WordPress on Azure App Service
Here’s a quick overview of the steps you need to take to put Front Door in front of an Azure Web App. In this case, the web app runs a WordPress site. Step 1: DNS Suppose you deployed the Web App and its name is gebawptest.azurewebsites.net and you want to reach the site via wp.baeke.info.…
Trying Civo’s Kubernetes Service
In a previous post I talked about k3sup, a tool to easily install k3s on any system available over SSH. If you don’t know what k3s is, it’s a lightweight version of Kubernetes. It also runs on ARMv7 and ARM64 processors. That means it’s also compatible with a Raspberry Pi. If I am not mistaken,…
Trying out k3sup
k3sup is a utility created by Alex Ellis to easily deploy k3s to any local or remote VM. In this post, I am giving the tool a try on a Civo cloud Ubuntu VM. You can of course pick any cloud provider you want or use a local system. Deploying a VM on Civo Cloud…
GitOps with Weaveworks Flux – Installing and Updating Applications
In a previous post, we installed Weaveworks Flux. Flux synchronizes the contents of a git repository with your Kubernetes cluster. Flux can easily be installed via a Helm chart. As an example, we installed Traefik by adding the following yaml to the synced repository: apiVersion: helm.fluxcd.io/v1 kind: HelmRelease metadata: name: traefik namespace: default annotations: fluxcd.io/ignore:…
GitOps with Weaveworks Flux
If you have ever deployed applications to Kubernetes or other platforms, you are probably used to the following approach: developers check in code which triggers CI (continuous integration) and eventually results in deployable artifacts a release process deploys the artifacts to one or more environments such as a development and a production environment In the…
AKS Azure Monitor metrics and alerts
In today’s post, we will take a quick look at Azure Kubernetes Service (AKS) metrics and alerts for Azure Monitor. Out of the box, Microsoft offers two ways to obtain metrics: Metrics that can easily be used with Azure Monitor to generate alerts; these metrics are written to the Azure Monitor metrics store Metrics forwarded…
Back to basics: DNS ALIAS records
A few days ago, I had to map the domain inity.io to a Netlify domain. If you have only worked with DNS once in your life, you probably know about these two types of records: A: an A record maps a name to an IP address CNAME: a CNAME record maps a name to another…
The basics of meshing Traefik 2.0 with Linkerd
A while ago, I blogged about Linkerd 2.x. In that post, I used a simple calculator API, reachable via an Azure Load Balancer. When you look at that traffic in Linkerd, you see the following: Above, you do not see this is Azure Load Balancer traffic. The traffic reaches the meshed service via the Azure…
