Kubernetes dashboard

9/21/2019

I have been able to successfully setup kubernetes on my Centos 7 server. On trying to get the dashboard working after following the documentation, running 'kubectl proxy' it attempts to run using 127.0.0.1:9001 and not my server ip. Do this mean I cannot access kubernetes dashboard outside the server? I need help on getting the dashboard running using my public ip

As I understand, you would like to access the dashboard from your laptop. What you should do is create an admin account called k8s-admin:

$ kubectl --namespace kube-system create serviceaccount k8s-admin
$ kubectl create clusterrolebinding k8s-admin --serviceaccount=kube-system:k8s-admin --clusterrole=cluster-admin

Then setup kubectl on your laptop, e.g. for macOS it looks like this (see documentation):

$ brew install kubernetes-cli

Setup a proxy to your workstation. Create a ~/.kube directory on your laptop and then scp the ~/.kube/config file from the k8s (Kubernetes) master to your ~/.kube directory.

Then get the authentication token you need to connect to the dashboard:

$ kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep k8s-admin | awk '{print $1}')

Now start the proxy:

$ kubectl proxy

Now open the dashboard by going to:

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/

You should see the Token option and then copy-paste the token from the prior step and Sign-In.

You can specify on which address you want to run kubectl proxy, i.e.

kubectl proxy --address <EXTERNAL-IP> -p 9001
Starting to serve on 100.105.***.***:9001

You can also use port forwarding to access the dashboard.

kubectl port-forward --address 0.0.0.0 pod/dashboard 8888:80

This will listen port 8888 on all addresses and route traffic directly to your pod.

For instance:

rsha:~$ kubectl port-forward --address 0.0.0.0 deploy/webserver 8888:80
Forwarding from 0.0.0.0:8888 -> 80

In another terminal running

rsha:~$ curl 100.105.***.***:8888
