Terminal User Interface for Docker Engine

Project Description

# sen

[![Circle CI](](
[![](]( "Get your own image badge on")

`sen` is a terminal user interface for docker engine:
* it can interactively manage your containers and images:
* manage? start, stop, restart, kill, delete,...
* there is a "dashboard" view for containers and images
* you are able to inspect containers and images
* sen can fetch logs of containers and even stream logs real-time
* some buffers support searching and filtering
* sen receives real-time updates from docker when anything changes
* e.g. if you pull a container in another terminal, sen will pick it up
* sen notifies you whenever something happens (and reports slow queries)
* supports a lot of vim-like keybindings (`j`, `k`, `gg`, `/`, ...)
* you can get interactive tree view of all images (equivalent of `docker images --tree`)

You can [see the features yourself](/docs/

# Installation and running `sen`

I strongly advise to run `sen` from a docker container provided on docker hub:

$ docker pull tomastomecek/sen

This repository has set up automated builds on docker hub. In case you run into some issue, try pulling latest version first before opening an issue.

This is the recommended way of running `sen` in a container:

$ docker run --privileged -v /var/run/docker.sock:/run/docker.sock -ti -e TERM tomastomecek/sen

Some distros have `/var/run` simlinked to `/run`, so you can do `/run/docker.sock:/run/docker.sock` instead.

In case you would like to try development version of sen, you can pull `tomastomecek/sen:dev`.

## docker

You can easily build a docker image with sen inside:

$ docker build --tag=$USER/sen
$ docker run --privileged -v /var/run/docker.sock:/run/docker.sock -ti -e TERM $USER/sen

## PyPI

`sen` releases are available on PyPI:

$ pip3 install sen

If `pip3` executable is not available on your system, you can run pip like this:

$ python3 -m pip install sen

And then start sen like this:

$ sen

## git

`sen` is a python 3 only project. I recommend using at least python 3.4. This is how you can install `sen` from git:

$ git clone
$ cd sen
$ pip3 install --user -r ./requirements.txt
$ ./ install
$ sen

Or even run `sen` straight from git:

$ git clone
$ cd sen
$ pip3 install --user -r ./requirements.txt

If `pip3` executable is not available on your system, you can run pip like this:

$ python3 -m pip install sen

# Prerequisite


* The unix socket for docker engine needs to be accessible. By default it's located at `/run/docker.sock`.


* Have the `DOCKER_HOST`, `DOCKER_TLS_VERIFY`, and `DOCKER_CERT_PATH` set properly. If you're using `docker-machine` or `boot2docker` you're all set!

# Keybindings

Since I am heavy `vim` user, these keybindings are trying to stay close to vim.

## Global

/ search (provide empty query to disable searching)
n next search occurrence
N previous search occurrence
f4 display only lines matching provided query (provide empty query to clear filtering)
f5 open a tree view of all images (`docker images --tree` equivalent)
ctrl o navigate to next buffer
ctrl i navigate to previous buffer
x remove buffer
q remove buffer, quit if no buffer is left
ctrl l redraw user interface
h, ? show help
: open command prompt

## Movement

gg, home go to first item
G, end go to last item
j go one line down
k go one line up
pg up
ctrl u go 10 lines up
pg down
ctrl d go 10 lines down

## Listing

@ refresh listing
f4 filtering, for more info run `help filter` in sen

## Image commands in listing

i inspect image
d remove image (irreversible!)
enter display detailed info about image (when layer is focused)

## Container commands in listing

i inspect container
l display logs of container
f follow logs of container
d remove container (irreversible!)
t stop container
s start container
r restart container
p pause container
u unpause container
b open container's mapped ports in a web-browser
X kill container
! toggle realtime updates of the interface (this is useful when you are removing multiple
objects and don't want the listing change during that so you accidentally remove something)

## Tree buffer

enter display detailed info about image (opens image info buffer)

## Image info buffer

enter display detailed info about image (when an image is focused)
i inspect image or container, whatever is focused

## Container info buffer

enter display detailed info about image (when image of the container is focued)
i inspect image (when image of the container is focued)

# Why I started sen?

Since I started using docker, I always dreamed of having a docker TUI. Something like [tig](, [htop]( or [alot]( Some appeared over time. Such as [docker-mon]( or [ctop]( Unfortunately, those are not proper docker TUIs. They are meant for monitoring and diagnostics.

So I realized that if I want make my dream come true, I need to do it myself. That's where I started working on *sen* (*dream* in Slovak).

But! As the time went, [someone]( else had the same idea as I did: [dry](
