k3s-multipass-cluster's Issues

Installation doesn't complete, needs k3s.yaml

I was facing this issue after running the awesome script:

[SUCCESS] Node k3s-worker3 k3s: Ready
[INFO] K3S_NODEIP_WORKER=192.168.64.26
[INFO] kubectl not configured because not "/Users/arash/.kube/k3s.yaml" not writable
[INFO] Use i.e.: "multipass exec k3s-master kubectl cluster-info"
[INFO] [helm] Install

Created an empty k3s.yaml under ~/.kube with

touch ~/.kube/k3s.yaml

and the installation goes through and works like a charm!

Conclusion: an empty k3s.yaml is need under ~/.kube/

THX!
