Configuring Istio using the Kubernetes Gateway API
The Kubernetes Gateway API is the successor of the Kubernetes Ingress API and is currently in beta state. More and more projects add support for the Gateway API like Istio. -> https://istio.io/latest/blog/2022/gateway-api-beta/ -> https://istio.io/latest/blog/2022/getting-started-gtwapi/ In today’s blog post, I walk you through how to configure Istio using the Kubernetes Gateway API. At the time of…

Run the Istio ingress gateway with TLS termination and TLS passthrough
The Istio ingress gateway supports two modes for dealing with TLS traffic: TLS termination and TLS passthrough. Running Istio with TLS termination is the default and standard configuration for most installations. Incoming TLS traffic is terminated at the Istio ingress gateway level and then sent to the destination service encrypted via mTLS within the service…

Monitor the Envoy Proxy ratelimit service with Azure Monitor for containers
The last two blog posts of this series covered the setup of the Envoy Proxy ratelimit service and its implementation with Istio. -> https://www.danielstechblog.io/run-the-envoy-proxy-ratelimit-service-for-istio-on-aks-with-azure-cache-for-redis/ -> https://www.danielstechblog.io/implement-rate-limiting-with-istio-on-azure-kubernetes-service/ In today’s post I walk you through on how to monitor the ratelimit service with Azure Monitor for containers. Not the standard monitoring of the container itself. We focus…

Implement rate limiting with Istio on Azure Kubernetes Service
In my last blog post I walked you through the setup of the rate limiting reference implementation: The Envoy Proxy ratelimit service. -> https://www.danielstechblog.io/run-the-envoy-proxy-ratelimit-service-for-istio-on-aks-with-azure-cache-for-redis/ Our today’s topic is about connecting the Istio ingress gateway to the ratelimit service. The first step for us is the Istio documentation. -> https://istio.io/latest/docs/tasks/policy-enforcement/rate-limit/ Connect Istio with the ratelimit service…

Run the Envoy Proxy ratelimit service for Istio on AKS with Azure Cache for Redis
The Istio sidecar proxy uses Envoy and therefore supports two different rate limiting modes. A local one targeting only a single service and a global one targeting the entire service mesh. The local rate limit implementation only requires Envoy itself without the need for a rate limit service. In contrast the global rate limit implementation…

Using distroless images in Istio on Azure Kubernetes Service
Looking at Docker Hub Istio provides the option using distroless images since version 1.3.0. As it is always a good idea on a Kubernetes cluster to reduce the attack surface, especially when running a managed Kubernetes cluster like Azure Kubernetes Service, using distroless images is one option of it. Per default Istio does not use…
