There is good documentation at https://hex.pm itself. You can host your own internal installation of hexpm (it’s a Phoenix app, yay! ) and then you can use the :repo option in the relevant depencies in the mix.exs file as noted in the docs here.

Apparently I’m still locked on this topic - @wojtekmach introduced MiniRepo roughly three months ago which looks like a good way to get a quick, private hex server up and running if cloning and deploying all of hex.pm proves to be overkill.

That said, I’ve found @ericmj and the hex.pm team to be extremely helpful and supportive. Seems like any of the above options will work well. Really just depends on personal preferences.

Git works if you have one or two packages but at the moment you have multiple packages and they depend each other, Hex private is probably the best option since we can’t perform dependency resolution on top of Git.
