Grout Wildcards

Why

Suppose you have a service which wants to handle requests over ad-hoc subdomains. E.g. Kubernetes cluster services exposed via custom subdomains.

Let's imagine your top level domain is custom.example.com and you want your service to handle HTTP/HTTPS traffic over custom.example.com and *.custom.example.com.

Setup

1. Configure a HTTPS load balancer for custom.example.com
2. Send traffic to Grout service IP addresses

PS: Sorry, currently SSL termination must be handled by you.

Connect

grout https://localhost:8080 custom.domain.com --wildcard

Now all requests to custom.example.com and *.custom.example.com will reach your grout client.

Viola!!!
