Using private packages in Go

goprivatepackage.md

If you were to go get a private repository with go, you would see something like this

$ go get github.com/zMrKrabz/flyent
go: downloading github.com/zMrKrabz/flyent v0.0.0-20210612205723-a495958a84ab
go get: github.com/zMrKrabz/flyent@v0.0.0-20210612205723-a495958a84ab: verifying module: github.com/zMrKrabz/flyent@v0.0.0-20210612205723-a495958a84ab: reading https://sum.golang.org/lookup/github.com/z!mr!krabz/flyent@v0.0.0-20210612205723-a495958a84ab: 410 Gone

In order to resolve this, use Github with SSH and set the GOPROXY to direct or set GOPRIVATE=.

1. Create a SSH key following this guide: https://jdblischak.github.io/2014-09-18-chicago/novice/git/05-sshkeys.html
2. Add your SSH key to github following this guide: https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh
3. Run git config --global url.git@github.com:.insteadof=https://github.com
4. To make sure that this is set, run git config --global --list
5. Set the GOPRIVATE to a regex string that matches the private packages you're getting. For the sake of simplicity, I just do $ export GOPRIVATE=github.com/<USERNAME>/* Because if one of my private packages uses a private package, it will be able to get that private package as well.
6. Rerun your go get command.
