Start dashboard and enable proxy in minikube

Start dashboard:

minikube dashboard

This will run dashboard only for 127.0.0.1, to enable proxying if you are on public computer - use kubectl:

kubectl proxy --address='0.0.0.0' --disable-filter=true

It will listen at the port 8001. This is dangerous for public instance, so make sure that you will allow the access to this port only to trusted IPs.
