Docker Cluster Monitor - A TUI utility to monitor your docker containers

A TUI tool for a live view of your docker containers running on a remote server. Here's a graphic of it running (refreshes every 5 seconds or so automatically):

Notice that it uses color to communicate outlier values. For example, low CPU is green, middle-of-the-road CPU is cyan, and heavy CPU usage is red. Similarly for memory. The memory limit column reflects the deploy>memory limit in Docker Compose for that container and the percentage reported is for the imposed memory limit rather than the machine physical memory limits.

Usage

To use the tool, it has one command, dockerstatus with a shorter alias ds. If you are running a set of Docker containers (say via Docker Compose) on server my-docker-host, then just run:

dockerstatus my-docker-host

You can optionally pass the username if you're not logging in as root. Here is the full help text (thank you Typer):

 Usage: dockerstatus [OPTIONS] HOST [USERNAME]                          
╭─ Arguments ───────────────────────────────────────────────────────────╮

│   username [USERNAME] The username of the ssh user for interacting    │
│                       with the server. [default: root]                │

Installation

This package is available on PyPI as dockerclustermon. However, it is ideally used as a CLI tool and not imported into programs. As such, using uv or pipx will be most useful. Take your pick:

uv

uv tool install dockerclustermon

Of course this requires that you have uv installed and in the path.

pipx

pipx install dockerclustermon

And this requires that you have pipx installed and in the path.

Compatibility

Docker Cluster Monitor has been tested against Ubunutu Linux. It should work on any system that supports SSH and has the Docker CLI tools installed. Note that it does not work on the local machine at the moment. PRs are welcome. ;)
