What you expected to happen?

No error or at least a meaningful error message, with which someone could actually debug things.

What happened?

Trying to setup a cluster via kURL with weave addon:

...

CoreDNS is running at https://192.168.15.47:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

The weave addon failed to deploy successfully.

How to reproduce it?

You would need to use the kURL installer I was given. I cannot make it smaller.

Anything else we need to know?
