Creating and Deploying Custom Hex Registries

In this post, Wojtek Mach explores the options available to Elixir developers for hosting private packages. While Hex.pm offers a hosted private packages service, the author focuses on alternatives for those needing full control over their infrastructure. Wojtek introduces the newly implemented solution in Hex v0.21 that simplifies creating local registries using the `mix hex.registry build` task. Detailed instructions are provided on setting up a local registry, publishing packages, and testing the setup. The post further discusses deploying the repository to Amazon S3 for reliability, and using Plug.Cowboy for customizable hosting. The conclusion highlights the benefits of this simpler solution and directs readers to a more comprehensive Hex.pm self-hosting guide.
