Terminal User Interface for Docker Engine

Project description

# sen

[![Code Issues](](
[![Circle CI](](

`sen` is a terminal user interface for docker engine:
* it can interactively manage your containers and images:
* manage? start, stop, restart, kill, delete,...
* you are able to inspect containers and images
* sen can fetch logs of containers and even stream logs real-time
* all buffers support searching and filtering
* sen receives real-time updates from docker when anything changes
* e.g. if you create 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`, `/`, ...)

# 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 before opening issue. You should run `sen` in containers like this:

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

## docker

You can easily build a docker image with sen inside:

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

## PyPI

`sen` releases are available on PyPI:

$ pip install sen
$ 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
$ ./ install
$ sen

Or even run `sen` straight from git:

$ git clone
$ cd sen

# Prerequisite

Bear in mind that unix socket for docker engine needs to be accessible. By default it's located at `/run/docker.sock`.

# 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)
* main listing provides additional filtering (for more info, check Listing Section)
* example query: "fed" - display lines containing string "fed"
ctrl o next buffer
ctrl i previous buffer
x remove buffer
h, ? show help

## Movement

gg go to first item
G 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 display only lines matching provided query (provide empty query to clear filtering)
* space-separated list of query strings, currently supported filters are:
* t[ype]=c[ontainer[s]]
* t[ype]=i[mage[s]]
* s[tate]=r[unning])
example query may be:
* "type=container" - show only containers (short equivalent is "t=c")
* "type=image fedora" - show images with string "fedora" in name (equivalent "t=i fedora")

## Image commands in listing

i inspect image
d remove image (irreversible!)

## Container commands in listing

i inspect container
l display logs of container
f follow logs of container
d remove container (irreversible!)
s stop container
t start container
r restart container
p pause container
u unpause container
X kill container

# 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).
