  • Cost optimize your Azure PostgreSQL Flexible Server deployments

    As I am currently preparing my session for Experts Live Germany about Azure Cost Optimization, I thought it might be good to share parts of the session as blog articles with the community. So, expect more to come in the next weeks and months. Today we focus on cost-optimizing Azure PostgreSQL Flexible Server deployments. Therefore, we look at the…

  • Using Istio with Kubernetes native sidecars on Azure Kubernetes Service

    In my previous blog post, I showed you how to check for specific feature gates on an Azure Kubernetes Service cluster. -> https://www.danielstechblog.io/show-enabled-feature-gates-on-an-azure-kubernetes-service-cluster/ Especially for the SidecarContainers feature gate, which is enabled on Azure Kubernetes Service running Kubernetes version 1.29 or higher. The SidecarContainers feature gate brings support for running sidecar containers as init containers. For instance, a service…

  • Show enabled feature gates on an Azure Kubernetes Service cluster

    Recently, I needed to check which feature gates are active on an Azure Kubernetes Service cluster running Kubernetes version 1.29.0. In particular, the SidecarContainers feature gate brings support for running sidecar containers as init containers. For instance, a service mesh proxy container now starts before the main container and solves a couple of issues with service…

  • Azure PostgreSQL Flexible Server – Feature set on par with Single Server

    The Azure PostgreSQL Flexible Server was from its launch the better option than the Single Server, especially from a performance perspective. However, the Flexible Server was missing important features that were built-in in the Single Server from the beginning. Since the retirement announcement of the Single Server, it was time for Microsoft to bring the…

  • Using HTTP status code 307/308 for HTTPS redirect with the Istio ingress gateway

    The gateway definition for the Istio ingress gateway provides a configuration parameter to enable the HTTPS redirect of HTTP connections. -> https://istio.io/latest/docs/reference/config/networking/gateway/#ServerTLSSettings apiVersion: networking.istio.io/v1beta1 kind: Gateway metadata: name: azst-aks-gateway namespace: istio-config spec: selector: istio: ingressgateway # use Istio default gateway implementation servers: – hosts: – “*.danielstechblog.de” port: number: 80 name: http protocol: HTTP tls: httpsRedirect:…

  • Fluent Bit and Kata Containers on Azure Kubernetes Service

    In the past, I have written two blog posts about how to run untrusted workloads on Azure Kubernetes Service. -> https://www.danielstechblog.io/running-gvisor-on-azure-kubernetes-service-for-sandboxing-containers/ -> https://www.danielstechblog.io/using-kata-containers-on-azure-kubernetes-service-for-sandboxing-containers/ Today, I walk you through how you gather log data of an untrusted workload isolated by Kata Containers with Fluent Bit. When you hear isolated, it always comes to mind that only…
