Missing docs - how to rehost the crates.io index

[chesedo]

The readme states the following

To use the proxy server, clone and rehost the crates.io index repository

I understand how to clone the repo, but I'm not quite sure how the rehosting part work 😅 Are there any pointers for this?

You need to host the local copy of the index git repository somewhere, so that your CI jobs have direct access to it.
I simply use a git repo on the same GitLab instance the Rust projects run their CI on. Or it can be a self-hosted git repo, doesn't matter.

My motivation for creating this tool was to make our self-hosted CI environment work even if the external internet connection fails. The distributed nature of git makes it a non-issue for the crates index, but the packages themselves are fetched via plain HTTP, hence the need for a caching proxy.

JFrom Artifactory has similar functionality: https://www.jfrog.com/confluence/display/JFROG/Cargo+Package+Registry

Unfortunately, we use Sonatype Nexus, which doesn't support Cargo yet...
