 # kubectl proxy
 Unfortunately, `kubectl proxy` can not be used to access k8dash. According to the information at [https://github.com/kubernetes/kubernetes/issues/38775#issuecomment-277915961](https://github.com/kubernetes/kubernetes/issues/38775#issuecomment-277915961), it seems that `kubectl proxy` strips the Authorization header when it proxies requests. From that link:
 
 > this is working as expected. "proxying" through the apiserver will not get you standard proxy behavior (preserving Authorization headers end-to-end), because the API is not being used as a standard proxy

 ## Running k8dash with OpenId Connect (oidc)
 k8dash makes using OpenId Connect for authentication easy. Assuming your cluster is configured to use OIDC, all you need to do is create a secret containing your credentials and run the [kubernetes-k8dash-oidc.yaml](https://raw.githubusercontent.com/herbrandson/k8dash/master/kubernetes-k8dash-oidc.yaml) config.
@@ -133,6 +142,8 @@ Additionally, there are a few other OIDC options you can provide via environment
 
 The other option is `OIDC_METADATA`. k8dash uses the excellent [node-openid-client](https://github.com/panva/node-openid-client) module. `OIDC_METADATA` will take a json string and pass it to the `Client` constructor. Docs [here](https://github.com/panva/node-openid-client/blob/master/docs/README.md#client). For example, `OIDC_METADATA='{"token_endpoint_auth_method":"client_secret_post"}`

 ## Running k8dash with NodePort
 If you do not have an ingress server setup, you can utilize a NodePort service as configured in the [kubernetes-k8dash-nodeport.yaml](https://raw.githubusercontent.com/herbrandson/k8dash/master/kubernetes-k8dash-nodeport.yaml). This is ideal when creating a single node master, or if you want to get up and running as fast as possible.

 ### Client
 The client is a React application (using TypeScript) with minimal other dependencies.
 
 To run the client, open a new terminal tab and navigate to the `/client` directory, run `npm i` and then `npm start`. This will open up a browser window to your local k8dash dashboard. If everything compiles correctly, it will load the site and then an error message will pop up `Unhandled Rejection (Error): Api request error: Forbidden...`. The error message has an 'X' in the top righthand corner to close that message. After you close it, you should see the UI where you can enter your token.
