Cli
Docker CLI is the command-line tool that enables users to interact with the Docker daemon for building, running, and managing containers. It provides a structured interface for controlling container lifecycles, images, networks, and volumes through a terminal-based workflow.
The tool supports building container images from source code using Dockerfiles, with features like build context streaming and image layer caching to accelerate construction. It also allows starting interactive shells inside containers for isolated development and testing environments.
The CLI operates through a client-server architecture, communicating with a remote Docker daemon over a REST API. A command-parsing pipeline tokenizes user input and dispatches it to handler functions, while a plugin-based extension system enables third-party subcommands and hooks. The daemon abstracts underlying container execution engines to manage lifecycle, isolation, and resource allocation.
Features
- Container Management Interfaces - Control container lifecycle, images, networks, and volumes through a command-line interface.
- CLI Command Dispatchers - User input is tokenized, parsed into a command tree, and dispatched to handler functions via a structured CLI framework.
- Container Lifecycle Management - Controlling container creation, start, stop, and removal through a command-line interface.
- Container Build Orchestrators - Build container images from source code using Dockerfiles and build contexts.
- Client-Server Daemon Architectures - The CLI communicates with a remote Docker daemon over a REST API to execute container management commands.
- Container Runtime Abstractions - The daemon abstracts underlying container execution engines (e.g., runc) to manage lifecycle, isolation, and resource allocation.
- CLI Plugin Systems - Third-party plugins extend CLI functionality by registering new subcommands and hooks through a defined interface.
- Container Development Environments - Start an interactive shell inside a container for isolated development and testing.
- Development Environment Setup - Starting interactive shells inside containers for isolated development and testing workflows.
- Build Context Injectors - Build contexts are tarred and streamed to the daemon, enabling remote builds without local file copies.
- Build Layer Caching - Builds reuse cached intermediate layers from previous runs, identified by content hashes, to accelerate image construction.
- Infrastructure and Automation - Command-line interface for the Docker engine.
