If you are not wed to git, and are willing to try something else, why not give Fossil SCM a try. It's created and maintained by the creator of SQLite. It's a single executable that provides everything for modern source code management, including a website, and even has an official docker file that just works.
Issue tracking, forum support, email, it's all there, in a single executable that can serve as both the front and back end depending on how you launch it. And it's a smaller install than git by itself.
