Great question today
I’m trying to get the port forwarding button working and it doesn’t seem to be creating the port forward. Also, I have other links added but they don’t automatically convert the URL from the service name to the hostname as is implied in the docs. (per Adding Buttons and Links | Replicated Docs)
My advice would be to start with this example and make sure it works, adding kots-app, k8s-app, and nginx to your application temporarily, then tweak it one thing at a time ( you can only have one kots-app a time though, so you may need to merge your files). Note that while this works well for NodePort and ClusterIP, its not currently usable for LoadBalancer services.
