This configuration abstracts golang module path,
to provide access to private go modules over git+ssh,
by setting dynamic html meta tags using nginx.

Workstation

Add Private URL

First, add the target URL to your $GOPRIVATE environment variable using one of the following methods: 

# ~/.config/go/env

GOPRIVATE="go.example.com/x/*"

Create Repo

mkdir hello && cd hello
git init
git remote add origin foo:/repos/hello

// main.go

package main
import "fmt"
func main() {
	fmt.Println("hello")
}

// go.mod

module willpittman.net/x/hello
go 1.18

git commit -m 'init'
git push

Package Consumers

# ~/.ssh/config

Host foo
  Hostname example.com
  IdentityFile ~/.ssh/user
  User user

go install example.com/x/hello

WebServer

# /usr/local/etc/nginx/nginx.conf

http {
    location / {
      root /usr/local/www/example.com;
      index index.html;
    }

    location ~ ^/x/(?<go_project>[^/]+)$ {
      root /usr/local/www/example.com;
      rewrite ^ /gopkg.html;
      sub_filter '{TARGET_PROJECT}' '$go_project'
      sub_filter_once off;
    }
}

<!-- /usr/local/www/example.com/gopkg.html -->
