When you perform a standard git push , code files travel to your primary repository host (like GitHub), while all .psd , .zip , and .mp4 binaries route directly into your AWS S3 bucket. 4. Advanced Management and Cost Optimization
. The URL follows this format:
Before starting the configuration, ensure you have the following prerequisites ready:
Now that your S3 bucket and middleware server are live, configure your local Git repository to route large file assets to your new setup. Open a terminal inside your local Git project directory. Initialize LFS tracking if you haven’t already: git lfs install Use code with caution.
Once deployed, your server will expose a public URL (e.g., https://yourcompany.com ). Step 4: Configure Your Local Git Repository lfs s3 account
(Note: For production environments, restrict AllowedOrigins to your specific internal corporate domains or Git server IP ranges). Step 2: Create a Dedicated IAM Policy and User
Git Large File Storage (LFS) is an open-source Git extension that replaces large files—such as audio samples, videos, datasets, or graphics—with text pointers inside your Git repository. The actual file contents are stored on a remote server. This significantly improves cloning and fetching times for repositories containing large assets.
Git LFS does not push files directly to S3 via standard Git protocols. Instead, it relies on an intermediate custom transfer agent or a lightweight LFS server.
Which one of these fits your needs best, or are you looking for a more specific technical tutorial? Git Large File Storage (LFS)
You deploy a lightweight, open-source Git LFS server that acts as a gatekeeper. When a developer runs git push or git pull , the Git LFS client communicates with this custom server. The server authenticates the user, generates secure, temporary AWS S3 Pre-signed URLs, and passes them back to the client. The client then uploads or downloads the heavy binaries directly to/from your S3 bucket. Popular open-source options include: Name it git-lfs-s3-user
]
By configuring Git LFS to use a custom S3 bucket, you:
Log in to your and navigate to the S3 Service . Click Create bucket .
by placing the LFS server URL in a .lfsconfig file at the root of your repository:
Major Git hosting providers charge premium rates for LFS storage and bandwidth. Amazon S3 offers incredibly cheap per-gigabyte storage rates and flexible storage classes (like Intelligent-Tiering), drastically reducing your infrastructure overhead. 2.

There isn't just one way to use S3 as an LFS backend. Understanding the options helps you pick the right tool for your workflow.
The initial setup – creating an S3 bucket, configuring an IAM user, and installing the appropriate tool – takes less than 30 minutes but delivers long‑term savings and flexibility. Your team can finally manage large binaries, datasets, and assets without the fear of slowing down your Git history or exceeding hosting limits. By following the security best practices outlined above, you can keep your LFS S3 setup both affordable and safe.
