Microsoft Orleans–Dependency Injection

Most .NET(Core) applications today use any kind of inversion of control. This is not different for a Microsoft Orleans application.

It leverages the ASP.NET Core built-in IoC container to allow you to inject dependencies in your grains:

This sounds really easy and in fact it is. The only thing you need to be aware of is that the Orleans application is NOT re-using the (ASP) .NET Core IoC container but uses it’s own instance. This is something I didn’t know and caused me a lot of headaches before I figured out the reason.

Microsoft Orleans is using similar concepts as ASP.NET Core but is not using the same builder. There are plans to integrate it directly when .NET Core 3.0 is released but at the moment of writing, you have to use a specific OrleansBuilder:

Important to notice in the code above is that the ConfigureServices() method you call here exposes a different IServicesCollection instance as the one used by ASP.NET Core.

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
