What is a “bare git” repository?
A “bare” Git repository is a special type of repository that does not have a working directory. Unlike a standard (non-bare) Git repository, which includes the actual project files and a .git directory, a bare repository contains only the .git directory and its contents. In other words, it stores the version control information, including commits, branches, and configuration, without any working files or directories.
The key characteristics of a bare Git repository are:
- No Working Directory: As mentioned earlier, a bare repository lacks a working directory. As a result, you cannot directly modify or view the files in a bare repository as you would with a regular (non-bare) repository.
- Shared Repository: Bare repositories are often used as shared repositories in centralized version control workflows. They serve as a central point for collaboration, where developers can push and pull changes from and to the repository.
- Remote Repositories: In distributed version control systems like Git, a bare repository is typically used on remote servers to facilitate collaboration. Developers clone the bare repository to their local machines, work on their changes, and then push those changes back to the bare repository for others to access.
- Naming Convention: By convention, bare repositories often have a .git extension in their names, such as “project-name.git.”
Using a bare repository as a central hub for collaboration has several benefits:
- Simplicity: Bare repositories are more lightweight and require less disk space compared to regular repositories because they do not store working files.
- Concurrency: Since there are no working files, multiple developers can push and pull changes simultaneously without conflicts or the risk of overwriting each other’s changes.
- Safety: Bare repositories are safer in a shared environment because they do not allow accidental changes to the project’s files, which could happen in a non-bare repository.
Here’s how you can create a bare Git repository:
git init --bare project-name.git
This command initializes a new bare repository named “project-name.git” in the current directory. Once the bare repository is created, you can place it on a remote server or shared location accessible to developers for collaboration.
