Building operator fails because of an invalid ~/.kube/config

I’m using version 3.0.0 of the dotnet-operator-sdk. I have a small project that I cannot compile due to an error in my ~/.kube/config.

When running dotnet build, it fails because the generated crds command fails. When I manually run that command, I get the stack trace below.

I understand it fails, because it is unable to parse my ~/.kube/config file because it doesn’t understand the provideClusterInfoProperty property in one of my contexts (I don’t know why it is there). Removing this property makes it work. What I don’t understand: why is the code generation step loading my ~/.kube/config? That shouldn’t be necessary to generate CRD’s, right?

>>> dotnet bin/Debug/netcoreapp5.0/Operator.dll generator crds --out /src/Operator/config/crds --format Yaml

Just found out, that the kubernetes client project could fix this error (see mention above).

This should be fixed by #169
