Unable to read auth data from kube config connected to external IAM #513
Thanks for opening the issue @nkuzman ! This will be a nice enhancement. The current k8s runtime capabilities are still very basic/experimental. Still ways to go before it's feature complete enough :-)
Expected Behavior
When running slim build on a running container in k8s cluster, authentication should be successfully read from cube config.
Actual Behavior
I'm using external IAM provider for k8s authentication. This is my configuration snapshot:
When I try to run docker build and connect it to a running container in k8s cluster, I get an error:
