<p>Is it possible to run two Kubernetes dashboard's locally within two different shells? I want to view two different cluster's at the same time, however, I run into an issue with the dashboard's port. </p>

<ol>
<li>Open Dashboard on 1st cluster</li>
<li>Open new shell and switch context to 2nd cluster</li>
<li>Open Dashboard on 2nd cluster</li>
</ol>

<p>I created the first dashboard like so: </p>

<pre><code>$ kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
$ kubectl proxy
Starting to serve on 127.0.0.1:8001
</code></pre>

<p>I opened a new shell and changed context to the new cluster receiving the error: </p>

<pre><code>$ listen tcp 127.0.0.1:8001: bind: address already in use
</code></pre>

<p>I understand <em>why</em> this is happening, however I'm not sure how to mitigate this problem. </p>

<p>Furthermore, when I change the port to 8002 for the second cluster's dashboard I'm unable to view both pages live without one rendering an <code>Internal Server Error (500): square/go-jose: error in cryptographic primitive</code> </p>

<p>I have switched to incognito, adding a Chrome configuration to erase/ignore browser cookies from localhost:8001 and localhost:8002, however when I go to login I receive the following error in the Chrome console: </p>

<pre><code>Possibly unhandled rejection: {  
"data":"MSG_LOGIN_UNAUTHORIZED_ERROR\n",
"status":401,
"config":{  
  "method":"GET",
  "transformRequest":[  
     null
  ],
  "transformResponse":[  
     null
  ],
  "jsonpCallbackParam":"callback",
  "url":"api/v1/rbac/status",
  "headers":{  
     "Accept":"application/json, text/plain, */*"
  }
},
  "statusText":"Unauthorized",
  "xhrStatus":"complete",
  "resource":{  

  }
}
</code></pre>

Baily
<p>The problem originates from the kubectl-proxy. The first one is using port 8001 and a port can be used only once.
You can start your second kubectl on a different port</p>

<pre><code>kubectl proxy --port=8002
</code></pre>

<p>You need to point your browser to the different port to access the other dashboard, of course.</p>
