🖥️ dtop

Important

dtop has been rewritten in Rust on the master branch. The Go version is available on the v1 branch. Version v0.3.x is the first release of the Rust version. There are some breaking changes compared to the previous version.

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 - Insanely fast and lightweight using Rust
• 🌍 Multi-host support - Monitor containers across multiple hosts
• 🔍 Dozzle - Supports opening Dozzle links via keyboard shortcuts
• 📝 Log streaming - View container logs in real-time

Roadmap

• Sort containers by name and status
• Implement log view streaming (basic)
• Add support for disk IO.
• Add support for Kubernetes clusters
• Search or filter for containers
• Support multiple certs for TLS
• Configurable columns and saving preferences
• Support simple JSON parsing and formatting

Installation

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

Docker

dtop is released as a docker image. You can pull it from Github.

docker run -v /var/run/docker.sock:/var/run/docker.sock -it ghcr.io/amir20/dtop

Currently, the image is available for amd64 and arm64 architectures.

Install from Source

dtop is written in Rust can be installed using Cargo.

cargo install dtop

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.

A terminal-based Docker container monitoring tool with real-time CPU and memory metrics

Usage: dtop [OPTIONS] [COMMAND]

Commands:
  update  Update dtop to the latest version
  help    Print this message or the help of the given subcommand(s)

Options:
  -H, --host <HOST>
          Docker host(s) to connect to. Can be specified multiple times.

          Examples: --host local                    (Connect to local Docker daemon) --host ssh://user@host          (Connect via SSH) --host ssh://user@host:2222     (Connect via SSH with custom port) --host tcp://host:2375          (Connect via TCP to remote Docker daemon) --host local --host ssh://user@server1 --host tcp://server2:2375  (Multiple hosts)

          If not specified, will use config file or default to "local"

  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

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/

See config.example.yaml for more examples.

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 - Establish an SSH connection 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 --host local --host tcp://host2:2375 --host ssh://user@host

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.
