What is cli?

This repository contains the command-line interface for Docker, the tool you type commands into when you use Docker to package, run, and share applications. If you've ever opened a terminal and typed something starting with "docker," you were interacting with the software that lives in this project. It's the bridge between you and Docker's underlying engine for creating and managing containers. At a high level, the CLI takes the commands you type and translates them into instructions that Docker's backend can act on. The README is fairly sparse on architectural detail, but it does explain that the project is developed using Docker itself. Contributors can spin up an interactive development environment to build binaries, run linting checks, and compile versions for different platforms, all from within a containerized setup. The included Makefile provides shortcuts for common tasks like building a Linux binary or creating builds for all supported operating systems. The people who would use this repository directly are developers contributing to Docker itself, the ones fixing bugs, adding features, or maintaining the command-line tool that ships with Docker CE and Docker EE. If you're simply using Docker to build and run containers, you don't need to clone this repo, the CLI comes bundled with your Docker installation. This project matters to someone who wants to understand how the Docker command works under the hood or who wants to contribute back to the open-source project. The project is licensed under Apache 2.0, and the legal section notes that Docker's use and transfer may be subject to government export restrictions, which is standard for software with broad international distribution. Beyond that, the README doesn't go into detail about the project's internal structure or design decisions, it's primarily a starting point for contributors who want to get set up quickly.
