  • 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…

  • 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…

  • Running Fluent Bit on Azure Linux in Azure Kubernetes Service

    In May this year, Microsoft announced the general availability of the Azure Linux support in Azure Kubernetes Service. -> https://azure.microsoft.com/en-us/updates/generally-available-azure-linux-support-in-aks/?WT.mc_id=AZ-MVP-5000119 -> https://techcommunity.microsoft.com/t5/linux-and-open-source-blog/introducing-the-azure-linux-container-host-for-aks/ba-p/3824101?WT.mc_id=AZ-MVP-5000119 Azure Linux is Microsoft’s Linux distribution of CBL-Mariner. -> https://github.com/microsoft/CBL-Mariner You can choose now between using Ubuntu or Azure Linux as the host operating system for your node pools in Azure Kubernetes Service,…
