Building, Installing and Setting up the Project

This document provides a step-by-step guide for building, installing, and setting up the docker/buildx project.

Prerequisites

• Go: The project requires Go version 1.16 or later.
• Docker: Docker Desktop or a compatible Docker environment.

Setting up a Development Environment

1. Clone the Repository:

   git clone https://github.com/docker/buildx.git
             cd buildx
             

2. Install Dependencies:

   make vendor 
             

3. Build the Project:

   make build 
             

   This will build the buildx binary in the build directory.

4. Run Tests:

   make test
             

   This runs all unit, integration, and driver tests.

Installing and Using buildx

1. Copy the Built Binary:

   Copy the buildx binary from the build directory to a location within your PATH.

2. Verify Installation:

   buildx version
             

   This command should output the buildx version.

Running buildx

Use the following command to run buildx:

buildx <command> [options]
          

Refer to the buildx documentation https://docs.docker.com/buildx/ for a detailed list of commands and options.

Contributing to the Project

To contribute to the buildx project, follow the standard GitHub workflow:

1. Fork the repository.
2. Create a new branch for your changes.
3. Make your changes and commit them.
4. Push your changes to your fork.
5. Create a pull request to the main repository.
