Chart Name

headscale

Is your feature request related to a problem? Please describe.

No problem, I would like to use the api externally and expose the api via ingress, any change we can get a 2nd ingress config to handle that?

Describe the solution you'd like

Probably add a 2nd ingress distinct from main called grpc or similar. Expose all the normal ingress options there.

Describe alternatives you've considered

I can manually create a 2nd ingress.
