I have created 3 Virtualbox VMs -> installed CentOS7 -> installed kubernetes via kubespray.
Dashboard container refuses to run after VM restart. Gives the following error:
goroutine 1 [running]:

2018/03/28 11:11:49 Could not init in cluster config: open /var/run/secrets/kubernetes.io/serviceaccount/token: no such file or directoryPlease help. I am a newbie in kubernetes and unable to find any clue on resolving it.
I updated the kubespray playbooks (synced with github). I guess few issues were resolved due to that. The steps to connect/configure to dashboard are as follows
```
# create admin user, as follows:
kubectl create -f admin.user
kubectl create -f clusterrolebinding.yaml
# get admin secret token
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
# get port on which dashboard is running
kubectl -n kube-system get service kubernetes-dashboard
# open the url, add the token found above to it. BINGO ! dashboard should open :)```
