[kube-up][scale-out] kubernetes-dashboard pod stuck in CrashLoopBackOff state

[h-w-chen]

What happened: after 1x1 kube-up scale-out cluster starts, found kubernetes-dashboard is stuck in CrashLoopBackOff state:

$ ./cluster/kubectl.sh --kubeconfig=cluster/kubeconfig.tp-1 get pod -n kube-system -l k8s-app=kubernetes-dashboard
NAME                                   HASHKEY               READY   STATUS             RESTARTS   AGE
kubernetes-dashboard-848965699-288nn   2434574577953097305   0/1     CrashLoopBackOff   8          25m

What you expected to happen: pod in Running state

How to reproduce it (as minimally and precisely as possible):

1. starts 1x1 kube-up scale-out cluster;
2. on TP master, run kubectl get pod -n kube-system -l k8s-app=kubernetes-dashboard

Anything else we need to know?:

Environment:

• Arktos version (use kubectl version):
• Cloud provider or hardware configuration:
• OS (e.g: cat /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools: kube-up scale-out 1x1
• Network plugin and version (if this is a network-related bug):
• Others:
