dtop

A terminal based dashboard for Docker that monitors multiple hosts in real-time.

Overview

dtop provides a comprehensive summary of all Docker containers running on your system, displayed directly in your terminal. Get instant visibility into container status, resource usage, and key metrics without leaving the command line. It supports ssh, tcp and local connections and integrates with Dozzle for container logs.

Features

• Real-time monitoring - Live updates of container status and metrics
• Lightweight - Minimal resource footprint
• Hyperlinks - Clickable links to container logs and stats using Dozzle

Roadmap

• Add support for disk IO.
• Add support for Kubernetes clusters
• Created detailed view, but not to compete with Dozzle
• Search or filter for containers
• Sort containers by name, status, or resource usage
• Configurable columns and saving preferences

Installation

dtop can be installed through multiple package managers or by downloading the binary directly.

Homebrew (macOS and Linux)

This is recommended for macOS and Linux users. Automatic updates are handled by Homebrew.

brew install --cask amir20/homebrew-dtop/dtop

Scoop (Windows)

dtop supports prebuilt binaries for Windows. You can install it using Scoop.

scoop bucket add amir20 https://github.com/amir20/scoop-dtop
scoop install amir20/dtop

Install Script

Downloads the latest release from GitHub.

curl -sSfL https://amir20.github.io/dtop/install.sh | bash

Install using Go

Downloads the latest release from source with Go.

go install github.com/amir20/dtop@latest

Command Line Options

By default, dtop will connect to the local Docker daemon using /var/run/docker.sock. DOCKER_HOST is also supported to connect to other hosts.

• --help - Display help information
• --hosts - A comma separated list of hosts to connect. Defaults to local

Configuration File

dtop supports command line flags or configuration file. The configuration file reads from the following locations:

• ./config.yaml
• ~/.dtop.yaml
• ~/.config/dtop/config.yaml

Note

Both yaml and yml files are supported.

Here's an example configuration:

hosts:
  - host: local
    dozzle: http://localhost:3100/ # this is optional
  - host: tcp://host2:2375
    dozzle: http://host2:3100/
  - host: ssh://user@host
    dozzle: http://host:8080/

Supported Connections

• Local Docker - Monitor containers running on the local Docker daemon using --hosts local
• Remote Docker - Monitor containers running on remote Docker daemons via SSH using --hosts tcp://host2:2375
• SSH Tunneling - Establish an SSH tunnel to a remote host and monitor containers running on it using --hosts ssh://user@host

You can connect to multiple hosts by separating them with commas:

dtop --hosts local,tcp://host2:2375,ssh://user@host

Dozzle Integration

dtop supports linking to container logs using Dozzle. To enable this feature, specify the Dozzle URL in the configuration file or command line flags. Once enabled, dtop will automatically open the Dozzle UI when you click on a container. dtop leverages OSC8 to send the URL to the terminal. iTerm, Ghostty and a few other terminals supports this with cmd+click or ctrl+click on the container name. For tmux, you need to have tmux version 3.4 or higher installed with hyperlinks enabled. This is usually enabled with set -as terminal-features ",*:hyperlinks".

Note

Currently, Dozzle url can only be configured in the configuration file. There is no way to provide it directly in the command line flags.

Related Projects & Inspirations

I am a big fan of ctop. ctop inspired me to create Dozzle but in the browser. However, it seems like ctop is no longer maintained. I considered forking ctop but deploying with same name would be challenging. I created dtop for my personal use case. I often want to see all my containers at a glance across multiple hosts. dtop achieves that by supporting remote hosts via ssh or tcp. Additionally, since I use Dozzle, I integrated Dozzle into dtop to provide a seamless experience for monitoring container logs.
