<p>Currently I started to use a kubernetes environment to deploy a react app. One thing that should be set are the healthiness and readiness probes. How should they look like for a react app, or are probes used for frontend apps?</p>

<p>If you have a separate pod for your front end, I assume a Web server like Apache or Nginx, the health check would just make sure the Webserver is alive. So you are correct that this would be a simple request, f.e. to the home page which is just static html. 
For the backend a different check would be in order. 
If you have just a single pod you need to check both with a health check. </p>
