YARP–Direct forwarding in .NET 6 and beyond

With YARP(Yet-Another-Reverse-Proxy) you can transform your ASP.NET Core application into a reverse proxy.

It offers features like routing, discovery, load balancing, retries,... However in the application I'm building that is a lot more then what I need. I only need the ability to take a specific request and forward it to a specific destination. In that case you can use Direct Forwarding through the IHttpForwarder.

IHttpForwarder supports:

  • Dynamic destination selection, you specify the destination for each request
  • Http client customization, you provide the HttpMessageInvoker
  • Request and response customization (except bodies)
  • Streaming protocols like gRPC and WebSockets
  • Error handling

It does not include:

  • Routing
  • Load balancing
  • Affinity
  • Retries

Direct forwarding in .NET 6 and beyond

You can find an example of Direct Forwarding in the documentation. However this documentation is written for .NET 5 still using the Startup.cs class.

Let me share an example on how to achieve the same thing in .NET 6:

You can find the complete example here: https://github.com/wullemsb/YarpDirectForwarding

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...
