I have an app which uses
My question is: how can I easily configure it to fetch
cowboy from another host? I would like to switch from
github.com to my own host.
You want to build cowboy that has two dependencies which are git repositories on GitHub (https://github.com/ninenines/cowlib and https://github.com/ninenines/ranch to be specific). But you want to fetch the repositories from some other host, like your company's own git server where you mirrored all public repositories you need.
You have a number of options:
rebar.config. This is the only (sane) way I know to make Rebar3 fetch the dependencies from a different location. The other options will target the layers below Rebar3 to achieve the same result.
git config --global url.https://git.mycompany.com/.insteadOf https://github.com/
/etc/hostsentry that resolves github.com to the IP of your server. You'll probably have to create a fake self-signed certificate for github.com, and make git on the build machine trust it. But you can do that following the advice here: https://stackoverflow.com/a/16543283/9015322
