AKS–The single biggest reason why you should apply a GitOps approach

GitOps is an approach to software delivery that uses Git as a single source of truth for declarative infrastructure and application deployment. With GitOps, all changes to infrastructure and applications are made through pull requests that are reviewed and approved before they are applied to the target environment. This approach offers several benefits, including improved visibility, traceability, but the single biggest reason why you should apply a GitOps approach is (enhanced) security compared to a traditional Continuous Delivery approach.

Flux

In Azure you can use GitOps in Azure Kubernetes Service (AKS) and Azure Arc-enabled Kubernetes clusters.Behind the scenes this uses Flux, a popular open-source tool set. Flux provides support for common file sources (Git and Helm repositories, Buckets, Azure Blob Storage) and template types (YAML, Helm, and Kustomize).

GitOps vs traditional Continuous Delivery(CD)

In a traditional CD setup, the CD tooling is running outside the AKS environment and the tool needs a lot of privileges on the cluster level to be able to successfully deploy the pods on the Kubernetes nodes. This is of course a security risk.

With GitOps the CD tooling(Flux in the case of AKS) runs inside the production cluster and it only needs access the code repository that is living outside the cluster. Of course it still needs privileges on the cluster but we don’t have to give an external tool access to our cluster which is a big advantage.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t

DevToys–A swiss army knife for developers

As a developer there are a lot of small tasks you need to do as part of your coding, debugging and testing activities. DevToys is an offline windows app that tries to help you with these tasks. Instead of using different websites you get a fully offline experience offering help for a large list of tasks. Many tools are available. Here is the current list: Converters JSON <> YAML Timestamp Number Base Cron Parser Encoders / Decoders HTML URL Base64 Text & Image GZip JWT Decoder Formatters JSON SQL XML Generators Hash (MD5, SHA1, SHA256, SHA512) UUID 1 and 4 Lorem Ipsum Checksum Text Escape / Unescape Inspector & Case Converter Regex Tester Text Comparer XML Validator Markdown Preview Graphic Color B
