How do I Generate a Self-signed Certificate using a domain name?

Help
1

1. The problem I’m having:

I don’t have a dns server available, so I appended a mapping to the hosts file for testing purposes.
like this:
192.168.89.51 test.mytestserver.dev
So I want to use caddy to generate a self-signed certificate for test.mytestserver.dev
But when I wrote the domain name in the caddyfile it applied for the publicly trusted certificate. for example through Let’s Encrypt.
But i want to generate by pki.ca.local…

I have seen in the documentation that tls internal is used.
But I don’t have a good understanding of it, and I might need an example that looks like my scenario.

thanks

This is what you want:

test.mytestserver.dev {
	tls internal
	reverse_proxy 127.0.0.1:8080
}
