Same issue here on k3s version v1.0.0 (18bd921).

Try setting the KUBECONFIG environment variable.
export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

That worked for me, but I only tried on a fresh CentOS/k3s/Helm install. Thanks @grawin

Same issue. The fix @grawin posted doesn't solve it for me though.

EDIT: I also tried the steps in https://github.com/ibrokethecloud/rancher-helm3 but to no avail.

The fix @grawin posted doesn't worked for me either, i'am using a ubuntu 18.04 system.

If you add "-v 20" to your helm command line it will show it's connecting to port 8080.
Running this seems to fix it:
kubectl config view --raw >~/.kube/config

This lets helm use the same config kubectl is using I think.
