Sounds neat but I couldn't follow what problem this was solving. Having an internal network that uses Lets Encrypt certs and updates automatically?
I solve that with Traefik in a docker container. It's setup with Cloudflare as my DNS provider using the DNS challenge and Lets Encrypt to issue certs. By slapping a few labels on any Docker container I get to use https and a subdomain on my real domain name. Everything is automatic and, while configuration was hard, I didn't have to custom roll anything special. I don't need an external VPS (but I do need Cloudflare to act as my domain provider, for free). Seems like that might be way easier for most people?
