Gitling is a smart HTTP git server designed for multi-tenant git contexts. Gitling allows for making an optional HTTP authentication request to an external URL in order to verify a push and set its location.

Note: Gitling only works for HTTP-based git. If you're looking for custom SSH git authentication (a la GitHub/Heroku), I wish you luck.

If you already have a go environment up and running, it's quite simple:

go get github.com/divshot/gitling

If you don't, you'll need to make that happen first. Binary distribution

Basic usage is as follows:

gitling --auth-url https://example.com/auth -p 8080 -r /path/to/root -b /usr/bin/git

Just try gitling -h if you need help with specific options.

If you specify an authorization URL using -a or --auth-url, Gitling will make an HTTP POST request to the specified URL.The request will have a JSON body containing details about the request. For instance, if I set my git remote as https://open:sesame@example.com/project-name.git and pushed, the request body would look like this:

{
  "username":"open",
  "password":"sesame",
  "path":"project-name.git"
}

Your response to this POST tells Gitling how to proceed. The first signal is the HTTP status code you return.

• 204: Authorization granted, path may be used without modification.
• 200: Authorization granted, response body as specified below.
• 401: Authentication failed (user/password combo did not grant access)
• 403: Authorization failed (user does not have access to repo at this path)
• 50x: If Gitling receives a 50x, it will print a generic error message.

In addition to HTTP status codes, a 200 response should be accompanied with a JSON object with one or more of the following keys:

• path: the path (relative to your project root) for the git repo.
• (TODO) read_only: if true, this user may not write to the repo, only read.
• (TODO) skip_create: don't create a new repository if one does not already exist.

If you don't specify a path, the path specified by the user will be used. For error responses (401, 403) the body of the response will be printed out for the user to see.

• "Push to Create" automatically initialize a bare repo on authorized push
• --template, -t to point at directory for repo template

• Allow for authentication via command, not just HTTP
