This is very useful: I am building an application that comprises multiple repos. I continue to procrastinate on whether using multiple repos vs. a monorepo was a good idea but, an issue that I have (had) is the need to ensure that the repos’ contents are using current|latest modules. GitHub can help. Most of the application is written in Golang with a smattering of Rust and some JavaScript. Aside Even though I’m more proficient with Golang, I want to become more proficient in Rust and I contemplated trying to write the entire application in Rust.

I think it would be valuable if Google were to provide volumes in Cloud Build of package registries (e.g. Go Modules; PyPi; Maven; NPM etc.). Google provides a mirror of a subset of Docker Hub. This confers several benefits: Google’s imprimatur; speed (latency); bandwidth; and convenience. The same benefits would apply to package registries. In the meantime, there’s a hacky way to gain some of the benefits of these when using Cloud Build.
