Managing Docker environments using the command line interface (CLI) is powerful but can become complex and time-consuming, especially as the number of containers, images, and volumes grows. Developers often have to memorize numerous Docker and Docker Compose commands to view logs, inspect containers, prune unused resources, or restart services. This workflow, while efficient for seasoned users, presents a steep learning curve for beginners and can slow down development for teams juggling multiple environments.
To address these challenges, developers are increasingly looking for a simpler, visual way to interact with Docker that still fits comfortably within their terminal-based workflows. A tool that combines the visual clarity of a graphical user interface (GUI) with the speed and portability of a terminal is exactly what Lazydocker delivers. It brings visibility and control to Docker environments without requiring users to leave their terminal.
Definition
Lazydocker is an intuitive terminal user interface (TUI) designed specifically for managing Docker containers, images, volumes, networks, and Docker Compose projects. Unlike traditional CLI methods, Lazydocker presents real-time, organized information through an interactive layout within the terminal itself.
Lazydocker is open-source, lightweight, and cross-platform, meaning it runs seamlessly on macOS, Linux, and Windows (using WSL). It is maintained by Jesse Duffield, the creator of Lazygit, and has gained popularity for making Docker workflows more accessible and less error-prone.

Core Features
Manage Containers
Lazydocker allows users to:
- View container logs in real time
- Monitor resource usage such as CPU and memory
- Execute shell commands inside running containers
- Restart, stop, and remove containers with simple key commands
Manage Images
Lazydocker provides an easy way to:
- View a list of local images
- Remove unused images
- Inspect image metadata
Manage Volumes and Networks
Users can list, inspect, and delete Docker volumes and networks from the same interface. This is particularly helpful when debugging connectivity or storage issues.
Docker Compose Support
For projects using Docker Compose, Lazydocker provides:
- Grouped views of all services
- Service-specific logs
- Easy controls to restart or rebuild individual services
Real-Time Terminal Updates
Unlike static CLI commands, Lazydocker refreshes data in real-time, giving instant feedback on container health, logs, and status changes.
Minimal Setup, Maximum Performance
Installation is quick and straightforward, requiring only a single binary or a Homebrew/Go install command. Lazydocker is designed to run efficiently, even on modest systems, without bloating the development environment.
Benefits
Simplified Docker Management
Lazydocker reduces the need for memorizing complex commands, making Docker more accessible to developers of all skill levels. Instead of running separate commands to inspect, log, or manage a container, users can perform all these tasks from one unified interface.
Faster Workflow
Switching between terminal tabs or retyping commands slows down development. Lazydocker’s intuitive navigation system speeds up these tasks, enabling developers to act faster, debug quicker, and ship more reliably.
Better Visibility
Real-time log streaming, CPU/memory stats, and container lifecycle insights provide a comprehensive view of the Docker environment. This visibility is essential for identifying problems early and maintaining container health.
Fewer Errors
By replacing complex commands with menu-driven actions, Lazydocker reduces the chances of command-line mistakes that could disrupt the environment or lead to data loss.
Common Use Cases
Local Development and Debugging
Developers running microservices locally benefit from Lazydocker’s quick access to logs, service status, and performance metrics. It becomes easier to detect misconfigured services or failing containers without jumping between terminal tabs.
Teaching and Demonstration
Lazydocker is a valuable teaching tool. New users learning Docker can see what each part of the system does visually, reducing the learning curve and reinforcing Docker concepts.
Lightweight Monitoring
For small-scale projects or local environments, Lazydocker offers a simple monitoring solution. Without the need for heavyweight dashboards like Portainer or Rancher, developers can use Lazydocker for real-time insight directly in the terminal.
How It Works
Terminal-Based Application
Lazydocker is built using Go and runs directly in the terminal. Its TUI layout is designed to be navigated using keyboard shortcuts, making it fast and responsive without relying on mouse interactions or graphical environments.
Interfaces with Docker Engine
Under the hood, Lazydocker interacts with Docker via its CLI and API. It issues familiar commands like docker ps, docker logs, or docker stats and presents their output in a structured, user-friendly format.
Docker and Docker Compose Required
To use Lazydocker effectively, Docker must be installed and running on the host system. For projects that use docker-compose.yml files, having Docker Compose installed unlocks Lazydocker’s Compose project views.
User Experience
Keyboard Navigation
Lazydocker is navigated entirely using the keyboard. Tabs and views can be switched with arrow keys or key combinations. Menus are intuitive, and each action (e.g., restart, remove, log view) is mapped to a key, reducing the time spent typing commands.
Organized Layout
The interface is divided into panels such as:
- Container List: Shows active/inactive containers with health indicators
- Logs Panel: Live log feed for the selected container
- Stats View: CPU and memory graphs
- Details Panel: Shows environment variables, network info, etc.
Quick Actions
Users can perform essential actions like:
- Restarting or stopping containers
- Pruning unused resources
- Executing commands inside containers
- Rebuilding Docker Compose services
All actions are just one or two keystrokes away.
Customization
Configuration via YAML
Lazydocker supports a customizable configuration file where users can:
- Define custom commands
- Change key bindings
- Adjust themes and layout preferences
- This flexibility makes Lazydocker adaptable to various team workflows and personal preferences.
Tailored Experience
Advanced users can configure Lazydocker to run specific shell commands, highlight important containers, or automatically open specific views at startup, enhancing productivity.
Background
Lazydocker was developed by Jesse Duffield, a software engineer also known for creating Lazygit. His motivation was to reduce friction in using Docker daily and bring clarity to managing multi-container environments.
Since its release, Lazydocker has gained widespread community support. Developers frequently contribute features, report issues, and help improve the tool. Its open-source nature ensures continuous updates and responsiveness to user needs.
