ASP.NET Core–Endpoint authorization

Until recently I always used an (empty) [Authorize] attribute on top of my Controllers to active authorization on a specific endpoint. (or I used a global AuthorizeFilter)

This will authorize users using the DefaultPolicy which just requires an authenticated user.

With the introduction of endpoint routing there is a new alternative. Disadvantage of the AuthorizeFilter or Authorize attribute are that these are MVC-only features.

A (better) solution is to use the RequireAuthorization() extension method on IEndpointConventionBuilder:

This has the same effect as applying an [Authorize] attribute on every controller.

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...
