`make test` fails

[Jonathan Hall]

Describe the bug
In my work on #42, I'm unable to successfully run the test suite, even on master. I've tried kind 0.9.0, as well as 0.8.1, which @willholley has reported successfully works for him.

Version of Helm and Kubernetes:

• Debian 10.5
• docker-ce version 18.06.3~ce
• kind v0.8.1 go1.15 linux/amd64

What happened:

$ make test
./test/e2e-kind.sh

Set kubectl context to "kind-chart-testing"
You can now use your cluster with:

kubectl cluster-info --context kind-chart-testing

Thanks for using kind! 😊
Copying kubeconfig to container...
error: Missing or incomplete configuration info.  Please point to an existing, complete config file:

  1. Via the command-line flag --kubeconfig
  2. Via the KUBECONFIG environment variable
  3. In your home directory as ~/.kube/config

To view or setup config directly use the 'config' command.

make: *** [Makefile:31: test] Error 1

What you expected to happen:

Tests pass.

How to reproduce it (as minimally and precisely as possible):

1. Install kind (GO111MODULE="on" go get sigs.k8s.io/kind@v0.8.1 && kind create cluster)
2. Run make test

Anything else we need to know:

I expect this is related to my local kubernetes config not matching what the tests expect. It probably just needs a small update to the README mentioning whatever the missing requirement is.

Small update: I've created a new user account with pristine Kubernetes config, and run the same test, and it's still failing. It must be something else. 😕

[Jonathan Hall]

After adding some set -x to e2e-kind.sh, I see that the failure occurs on this command:

+ docker_exec kubectl cluster-info
+ docker exec --interactive ct kubectl cluster-info

So I added a kubectl config view before that, and see:

+ docker_exec kubectl config view
+ docker exec --interactive ct kubectl config view
apiVersion: v1
clusters: null
contexts: null
current-context: ""
kind: Config
preferences: {}
users: null

I'm not sure what I should be expecting to see, though. 🤔
