(Corporate) Git Proxy

Many corporations, especially financial services have strict policies towards opensource contributions. On rare occasions when a developer can contribute to open source, information security and compliance officers often demand complex shadow processes are set up to ensure code reviews, scans and other processes are adhered to before a push to the public repo takes place.

We wish to keep the process for the developer as simple and familiar as possible, therefore we feel the solution is a proxy that sits between the developer and the public repository.

The idea is quite simple, scan outgoing attempts to push to public repository and raise compliance/info-sec friendly checks before allowing the push to complete.

Of course every corporation will have different procedures so a key feature has to be the extensibility of the framework.

Project Installation Instructions

All contributions are welcome. Please fork the repository before local development.

Clone git-proxy using git clone <repo path>/git-proxy
Navigate to project directory with cd git-proxy

Install and run

Install project dependencies using npm i or npm install
Start Express server using npm start after the project has installed.

 git-proxy@0.0.1 start C:\projects\github-proxy
 concurrently "npm run server" "npm run client

Testing a Repo Through the Proxy

Now the project is running, lets test a repo through the proxy. Clone a repo that is in the authorised list (see /resources/config.json)

c:\projects\
git clone http://localhost:8000/finos/test-allowed-repo

Edit the README.md file in 'test-allowed-repo' repo
run 'push.bat'
You should see some activity in the node.js proxy windows
Everything should have pushed to the remote repo.

Testing a non-authorised-repo

Clone a repo that is not in the authorised list (see /resources/config.json), for example:

c:\projects\
git clone http://localhost:8000/finos/test-banned-repo

Edit the README.md file in 'test-allowed-repo' repo
run 'push.bat'
You should see some activity in the node.js proxy windows
The git push should result in an error

The push essentially rejected

Local Project Configuration

The file user-settings.json exists in the project root to override config.json for local developer configuration. The following describes how to use user-settings.json

If the file exists in the project root user-settings.json overrides config.json
If user-settings.json does not exist config.json is used.
The json format of user-settings.json mirrors config.json. This enables local development scenarios, such as forking test repos as illustrated below.
- Fork finos/test-allowed-repo and finos/test-banned-repo
- Add the forked test-allowed-repo to user-settings.json in your project root as below ...
```
{
  "repoAuthorisedList": [
    "<git project>/test-allowed-repo.git"
  ]
}
```
Run git clone http://localhost:8000/<git project>/test-allowed-repo
Run git clone http://localhost:8000/<git project>/test-banned-repo
Edit the README.md file in test-allowed-repo and test-banned-repo repo.
Run the git instructions highlighted in push.bat as illustrated in Testing a Repo Through the Proxy.

The project is now set up for local development, including git push origin main to your forked repos.
