KUBECONFIG with multiple entries doesn't work when running the container

Both config files are valid. It works if either one is removed from the KUBECONFIG var.

yeah, I think the -v $KUBECONFIG:/kubeconfig -e KUBECONFIG=/kubeconfig does not allow for that. it's assuming a single file

If you truely need this, you can do -v $DIR_WITH_KUBECONFIGS:/kubeconfig -e KUBECONFIG=/kubeconfig/kube1.conf:/kubeconfig/kube2.conf

but cnf-tests cant run on multiple clusters, so I think you'd better pass it a single conf file

[jc-rh]

Right, we never meant to run it on multiple clusters. It's just a convenience thing. We often switch contexts between clusters and compare results. And it's not super straightforward to merge multiple cluster config into one single file.
