Let's Encrypt with DNS Validation for Keycloak without a Domain

How DNS Validation Works with Let's Encrypt

Unlike HTTP validation (which requires a public domain), DNS validation works by:

1. Having you create specific DNS TXT records to prove you control the DNS for your hostnames
2. Let's Encrypt verifies these records before issuing certificates

Implementation Steps

Context

This is for programmers who want to ramp on Go, without resources that reiterate programming fundamentals. This would not be a good list of resources for folks who are learning to program using Go as their first language. Some resources that I dismiss here would be super valuable for newer folks. This is a selection of resources for those who understand programming fundamentals in a different language already.

Advice

1. First steps = Tour of Go
2. Don't waste time on Go Fundamentals-type books - it all lives in tour of Go.
3. Consider joining the Gophers Slack
4. When you need help, the Go Playground allows you make a quick scratch file and share it. Others trying to help can run your code easily this way.
