k8s-proxy

Simple reverse proxy to serve the Kubernetes dashboard with Google OIDC as the identity provider. Technically, any OIDC provider should work but this has been tested only with Google for the moment.

This project will allow you to access the dashboard without having to paste the JWT token in the UI and paste a new one once it expires. It handles the refresh of the token and the injection of the JWE token on each request. This makes a transparent solution until this PR is merged.

Disclaimer

This project was made as part of a hackathon so it's rough around the edges, might contains bugs and have a couple of things hardcoded. Feel free to open a PR or an issue if you find anything.

How to use

The proxy needs a couple of parameters before it can start. You can inject those properties in a yaml file or with command line argument.

YAML configuration

Create a application.yml file next to the .jar file :

server:
  port: 8888

google: 
  clientId: insert client id from Google here
  clientSecret: insert client secret from Google here
  authorizeUrl: https://accounts.google.com/o/oauth2/auth
  tokenUrl: https://www.googleapis.com/oauth2/v4/token
  
k8s:
  clusterEndpoint: https://your.k8scluster.com

Command line argument

You can inject the required parameter on the command line as such :

java -jar -Dgoogle.clientId=something -Dgoogle.clientSecret=secret -Dgoogle.authorizeUrl=https://accounts.google.com/o/oauth2/auth -Dgoogle.tokenUrl=https://www.googleapis.com/oauth2/v4/token -Dk8s.clusterEndpoint=https://your.k8scluster.com k8s-proxy-0.0.1.jar

Run the jar file

1. Download the latest release version.
2. Run the jar file with java -jar k8s-proxy-0.0.1.jar
3. Access the proxy at http://localhost:8888/ui
