oxker

A simple tui to view & control docker containers

Built in Rust, making heavy use of ratatui & Bollard

Download & install

Cargo

Published on crates.io, so if you have cargo installed, simply run

cargo install oxker

Docker

Published on Docker Hub and ghcr.io, with images built for linux/amd64, linux/arm64, and linux/arm/v6

via Docker Hub

docker run --rm -it -v /var/run/docker.sock:/var/run/docker.sock:ro --pull=always mrjackwills/oxker

via ghcr.io

docker run --rm -it -v /var/run/docker.sock:/var/run/docker.sock:ro --pull=always ghcr.io/mrjackwills/oxker

Nix

Using nix flakes, oxker can be ran directly with

nix run nixpkgs#oxker

Without flakes, you can build a shell that contains oxker using

nix-shell -p oxker

AUR

oxker can be installed from the AUR with using an AUR helper:

paru -S oxker

Pre-Built

See the pre-built binaries

or, download & install (x86_64 one liner)

wget https://www.github.com/mrjackwills/oxker/releases/latest/download/oxker_linux_x86_64.tar.gz &&
tar xzvf oxker_linux_x86_64.tar.gz oxker &&
install -Dm 755 oxker -t "${HOME}/.local/bin" &&
rm oxker_linux_x86_64.tar.gz oxker

or, for automatic platform selection, download, and installation (to $HOME/.local/bin)

One should always verify script content before running in a shell

curl https://raw.githubusercontent.com/mrjackwills/oxker/main/install.sh | bash

Run

oxker

In application controls

button result
( tab ) or ( shift+tab ) Change panel, clicking on a panel also changes the selected panel.
( ↑ ↓ ) or ( j k ) or ( PgUp PgDown ) or ( Home End ) Change selected line in selected panel, mouse scroll also changes selected line.
( enter ) Run selected docker command.
( 1-9 ) Sort containers by heading, clicking on headings also sorts the selected column.
( 0 ) Stop sorting.
( e ) Exec into the selected container - not available on Windows.
( h ) Toggle help menu.
( m ) Toggle mouse capture - if disabled, text on screen can be selected.
( q ) Quit.
( s ) Save logs to $HOME/[container_name]_[timestamp].log, or the directory set by --save-dir.
( esc ) Close dialog.

Available command line arguments

argument result
-d [number > 0] Set the minimum update interval for docker information in milliseconds. Defaults to 1000 (1 second).
-r Show raw logs. By default, removes ANSI formatting (conflicts with -c).
-c Attempt to color the logs (conflicts with -r).
-t Remove timestamps from each log entry.
-s If running via Docker, will display the oxker container.
-g No TUI, essentially a debugging mode with limited functionality, for now.
--host [string] Connect to Docker with a custom hostname. Defaults to /var/run/docker.sock. Will use $DOCKER_HOST environment variable if set.
--save-dir [string] Save exported logs into a custom directory. Defaults to $HOME.
--use-cli Use the Docker application when exec-ing into a container, instead of the Docker API.

Build step

x86_64

cargo build --release

Raspberry pi

requires docker & cross-rs

64bit pi (pi 4, pi zero w 2)

cross build --target aarch64-unknown-linux-gnu --release

32bit pi (pi zero w)

Tested, and fully working on pi zero w, running Raspberry Pi OS 32 bit, the initial logs parsing can take an extended period of time if thousands of lines long, suggest running with a -d argument of 5000

cross build --target arm-unknown-linux-musleabihf --release

If no memory information available, try appending /boot/cmdline.txt with

cgroup_enable=cpuset cgroup_enable=memory

see https://forums.raspberrypi.com/viewtopic.php?t=203128 and https://github.com/docker/for-linux/issues/1112

Untested on other platforms

Tests

As of yet untested, needs work

The work has been done, so far the tests don't effect any running containers, but this may change in the future.

cargo test

Run some example docker images

using docker-compose.yml;

docker compose -f docker-compose.yml up -d

or individually

docker run --name redis -d redis:alpine3.19
docker run --name postgres -e POSTGRES_PASSWORD=never_use_this_password_in_production -d postgres:alpine3.19
docker run -d --hostname my-rabbit --name rabbitmq rabbitmq:3
