Dashboard: Unable to reinstall dashboard

[andrei-dascalu]

Environment

Dashboard version: v1.8.3 
Kubernetes version: v1.10.0
Operating system: Linux docker5 4.9.80-hypriotos-v7+ #1 SMP Tue Mar 27 07:46:13 UTC 2018 armv7l GNU/Linux  (RaspberryPi3, HypriotOS) 
Node.js version:
Go version:

Steps to reproduce

1. Deploy dashboard: kubectl apply -f https://github.com/kubernetes/dashboard/blob/v1.8.3/src/deploy/recommended/kubernetes-dashboard-arm.yaml
2. Remove dashboard:

• kubectl delete deployment kubernetes-dashboard --namespace=kube-system
• kubectl delete service kubernetes-dashboard --namespace=kube-system
• kubectl delete role kubernetes-dashboard-minimal --namespace=kube-system
• kubectl delete rolebinding kubernetes-dashboard-minimal --namespace=kube-system
• kubectl delete sa kubernetes-dashboard --namespace=kube-system
• kubectl delete secret kubernetes-dashboard-certs --namespace=kube-system
• kubectl delete secret kubernetes-dashboard-key-holder --namespace=kube-system

1. Try to deploy again:
   kubectl apply -f https://github.com/kubernetes/dashboard/blob/v1.8.3/src/deploy/recommended/kubernetes-dashboard-arm.yaml

Observed result

error: error converting YAML to JSON: yaml: line 325: mapping values are not allowed in this context

Expected result

deploy successful

Comments

Seems strange that it reports an error on the non-existent line 325 as if the yaml were concatenated against another file. Also, it's the exact same command that previously worked.

I think it's better to use raw.

https://raw.githubusercontent.com/kubernetes/dashboard/v1.8.3/src/deploy/recommended/kubernetes-dashboard.yaml

just try:
curl https://github.com/kubernetes/dashboard/blob/v1.8.3/src/deploy/recommended/kubernetes-dashboard-arm.yaml
and
curl https://raw.githubusercontent.com/kubernetes/dashboard/v1.8.3/src/deploy/recommended/kubernetes-dashboard.yaml

[andrei-dascalu]

No difference, regardless of which I use I can't reinstall the dashboard after an initial installation.

@andrei-dascalu why? just try:

1. kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.8.3/src/deploy/recommended/kubernetes-dashboard.yaml

2. kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.8.3/src/deploy/recommended/kubernetes-dashboard.yaml

3. kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.8.3/src/deploy/recommended/kubernetes-dashboard.yaml
