Remote Git Repository Infrastructure suggestion? (Blue Maps)

Question

I have been thinking awhile how to achieve the below goals for quite awhile. Think I'm not expert in Git to have enough knowledge to craft a good infrastructure. Anyone of you can give me the suggestions?

Scenario:

Product A, B, C Client X, Y, Z

Client X has Product A only.
Client Y has Product A and B.
Client Z has Product B and C.

Initially I was thinking the base should be Repo A, B and C separately and each of them will have separate module in different folder in case Client has specific request on the product. But later something comes into my mind, what if I fetch and pull from Repo A? Will the separate module being pulled together at once? How should I do it or any other better infrastructure?

No: each repo is independent.

I would recommend three additional repos, for referencing the right submodules.

• RepoX for Client X: references one submodule A
• RepoY for Client Y: references two submodules A and B
• RepoX for Client Z: references two submodules B and C

The idea (with submodules) to record the exact SHA1 of each product you need for a given client.
that way, if you pull one Product repo:

• it doesn't have any influence on the other Product repos
• you go back one level up in the parent repo (a Client repo), add and commit the new state of your submodule, recording the change you made in said submodule.
