Hi. It's super cool that you're building a way to host gem servers on google cloud.
You forked this repo from the Gemstash repo at https://github.com/bundler/gemstash. Not only did you not credit the Gemstash project in any way, that repo is licensed MIT. As I'm sure you're aware, the MIT license requires you to preserve copyright information, and does not allow you to change the license.
Instead of following the MIT license, you removed the MIT license from the repo, removed the copyright information, and added the Apache license to every file.
That's not okay.
From a legal standpoint, this repo is not acceptable, and I'm prepared to get my lawyers involved if I don't hear back from you soon.
From an ethical standpoint, this is also super gross: Gemstash is a project created and maintained by the Ruby non-profit that I founded, Ruby Together. GCP has repeatedly declined to support Ruby Together in the work that it does to keep RubyGems.org, Bundler, and RubyGems itself maintained. Stealing software from a non-profit that you refuse to support, even though you depend on the work it does, is extremely not cool.
