ASP.NET Core: Set the environment on your Powershell prompt

While trying to run our ASP.NET Core application from the commandline using ‘dotnet run’ we got the following warning:

Development environment should not be enabled in deployed applications, as it can result in sensitive information from exceptions being displayed to end users. For local debugging, development environment can be enabled by setting the ASPNETCORE_ENVIRONMENT environment variable to Development, and restarting the application.
Makes sense, however in this case we would like to run the application using “Development” as the configured environment.

How can we do that?

From the command prompt:

setx ASPNETCORE_ENVIRONMENT "Development"
dotnet run

From Powershell:

$Env:ASPNETCORE_ENVIRONMENT = "Development"
dotnet run
Remark: Note that the environment change will only apply to the current window. So it is important to run both commands from the same command prompt

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...
