You need to run kubectl proxy locally for accessing the dashboard outside the kubernetes cluster. You need to scp admin.conf file (file on your kubernetes master at /etc/kubernetes/admin.conf) to the machine from which you want to access the dashboard and pass it to kubectl command. Please, refer to following posts:
