Kustomize and Flux

Flux has a feature called manifest generation that works together with Kustomize. Instead of just picking YAML files from a git repo and applying them, customisation is performed with the kustomize build command. The resulting YAML then gets applied to your cluster. If you don’t know how customisation works (without Flux), take a look at … Continue reading “Kustomize and Flux”

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 … Continue reading “Deploy AKS with Nginx, External DNS, Helm Operator and Flux”

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: … Continue reading “GitOps with Weaveworks Flux – Installing and Updating Applications”

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 … Continue reading “GitOps with Weaveworks Flux”

Giving Argo CD a spin

If you have followed my blog a little, you have seen a few posts about GitOps with Flux CD. This time, I am taking a look at Argo CD which, like Flux CD, is a GitOps tool to deploy applications from manifests in a git repository. Don’t want to read this whole thing? There are … Continue reading “Giving Argo CD a spin”

A quick tour of Kustomize

Image above from: https://kustomize.io/ When you have to deploy an application to multiple environments like dev, test and production there are many solutions available to you. You can manually deploy the app (Nooooooo! 😉), use a CI/CD system like Azure DevOps and its release pipelines (with or without Helm) or maybe even a “GitOps” approach … Continue reading “A quick tour of Kustomize”

Creating Kubernetes secrets from Key Vault

If you do any sort of development, you often have to deal with secrets. There are many ways to deal with secrets, one of them is retrieving the secrets from a secure system from your own code. When your application runs on Kubernetes and your code (or 3rd party code) cannot be configured to retrieve … Continue reading “Creating Kubernetes secrets from Key Vault”

Use a Power Automate Button to start an Azure DevOps build on the go

In a previous post, we built a pipeline to deploy AKS using Azure DevOps. Because it can take while to deploy, it can be handy to start the deployment at any time without having to logon to Azure DevOps. There are many ways to achieve this, but one of the easiest ways is Power Automate. … Continue reading “Use a Power Automate Button to start an Azure DevOps build on the go”

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 … Continue reading “Check your yaml files with kubeval and GitHub Actions”
