minikube dashboard 활성화, 접속 방법

minikube의 대시보드를 활성화 시켜봄

 

일단 첫번째로 addons를 확인해봐야함

 

minikube addons list로 addons가 활성화 상태인 지 비활성화 상태인 지 확인할 수 있음

[ddadmin@edge .kube]$ minikube addons list

만약 dashboard가 비활성화 상태라면 다음 커맨드로 활성화 시켜줘야함.

minikube addons enable dashboard

 

그 다음 minikube dashboard 명령을 입력하면 대시보드가 활성화된다.

그런데 url이 hostname이나 본인 ip가 아닌 localhost임

minikube를 서버에 올려서 아래 url의127.0.0.1와 내 윈도우 pc에서 입력한 127.0.0.1은 다름. 즉 접속불가

external ip로 접속 가능하게 세팅이 필요함.

[ddadmin@edge .kube]$ minikube dashboard
* Verifying dashboard health ...
* Launching proxy ...
* Verifying proxy health ...
* Opening http://127.0.0.1:41708/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/ in your default browser...

 

proxy 설정을 해줌. 아래 error는 이미 한번 돌려서 에러난거임

foreground라서 커맨드를 입력하면 다른 작업을 못함

nohup으로 background에서 돌게 해줬음

맨 밑에 0.0.0.0:8001:은 잘 기억해둬야함. dashboard 접속할 때 8001로 들어가야됌 (default값임)

[ddadmin@edge .kube]$ kubectl proxy --address='0.0.0.0' --disable-filter=true &
W0313 04:44:38.770361   96272 proxy.go:175] Request filter disabled, your proxy is vulnerable to XSRF attacks, please be cautious
error: listen tcp 0.0.0.0:8001: bind: address already in use

 

다시 dashboard를 실행해봄

dashboard도 마찬가지로 foreground process라서 nohup으로 돌림

[ddadmin@edge .kube]$ * Verifying dashboard health ...
* Launching proxy ...
* Verifying proxy health ...
* Opening http://127.0.0.1:36004/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/ in your default browser...
  http://127.0.0.1:36004/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/

 

url에서 ip:port만 서버ip:8001로 바꾼 후 chrome에서 접속해봄

dashboard도 잘 올라왔고 노드들의 정보도 잘 가져오고 있음

참고

 

kubectl proxy stop하는 방법

[ddadmin@edge root]$ ps -ef | grep "kubectl proxy"
ddadmin    70568       1  0 04:04 ?        00:00:01 kubectl proxy --address=0.0.0.0 --disable-filter=true
ddadmin   112333  109434  0 05:09 pts/1    00:00:00 grep --color=auto kubectl proxy
[ddadmin@edge root]$ kill -9 70568

 

minikube dashboard는 kubernetes-dashboard라는 namespace에 올라가 있음

[ddadmin@edge root]$ kubectl get pods --namespace=kubernetes-dashboard
