Closed liangruibupt closed 5 years ago

Problem description

If you directly use the official command, the default image registry will be k8s.gcr.io, you have to through http proxy.

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

otherwise, you will encounter error

[ec2-user@ip-172-16-180-167 kops-cn-master]$ kubectl -n kube-system get pod | grep kubernetes-dashboard
kubernetes-dashboard-65c76f6c97-d8x77                                   0/1     ImagePullBackOff   0          3m56s

[ec2-user@ip-172-16-180-167 kops-cn-master]$ kubectl describe pod -n kube-system kubernetes-dashboard
Warning  Failed     6m2s (x4 over 8m8s)    kubelet, ip-172-16-86-107.cn-northwest-1.compute.internal  Failed to pull image "k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1": rpc error: code = Unknown desc = Error response from daemon: Get https://k8s.gcr.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
  Warning  Failed     6m2s (x4 over 8m8s)    kubelet, ip-172-16-86-107.cn-northwest-1.compute.internal  Error: ErrImagePull

How to fix it?

1. curl -sS https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml -o kubernetes-dashboard.yaml
2. change the kubernetes-dashboard.yaml image: from 
k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1 to 937788672844.dkr.ecr.cn-north-1.amazonaws.com.cn/kubernetes-dashboard-amd64:v1.10.1
3. kubectl apply -f kubernetes-dashboard.yaml

close it as know issue

Maybe this would be better.

Haven't tried it yet. But should work.

 helm install stable/kubernetes-dashboard \
--name kubernetes-dashboard \
--set image.repository=937788672844.dkr.ecr.cn-north-1.amazonaws.com.cn/kubernete
s-dashboard-amd64 \
--namespace kube-system
