xdocker

eXtended docker

Nicolas MULLER, 2015

Extended CLI for docker because typing long docker commands is boring...

Project built with :

• Cobra, a commander for modern Go CLI interactions .
• Viper, Go configuration with fangs, companion to cobra
• DockerClient, a Docker client library in Go

Thanks to all developpers about these libraries !

INSTALL FROM SOURCE

You must know at least how to compile Go sources and have the golang runtime with you.

cd ~
mkdir bin
cd bin
git clone git@github.com:Treeptik/xdocker.git
cd xdocker
go build xdocker.go

Now add this somewhere to your ~/.bashrc:

export PATH=$PATH:$GOPATH/src/xdocker/xdocker

Warning: Some of these commands may be destructive - use at your own risk and test on a test system before using in a production environment.

INSTALL WITH DOCKER

Why install xDocker with docker ? Because it’s fun ! Therefore, you won’t mind if my method to build nsenter uses Docker itself.

If you want to install xdocker into /usr/local/bin, just do this:

docker run --rm -v /usr/local/bin:/target treeptik/xdocker

The treeptik/xdocker container will detect that /target is a mountpoint, and it will copy the xdocker binary into it.

If you don’t trust me, and prefer to extract the xdocker binary, rather than allowing my container to potentially wreak havoc into your system’s $PATH, you can also do this:

docker run --rm treeptik/xdocker cat /xdocker > /tmp/xdocker && chmod +x /tmp/xdocker

Then do whatever you want with the binary in /tmp/xdocker.

Command quick reference

• kill [all|rex] - Kill all containers or these named and provided by regular expression. The option all required an confirmation else you must force it.

Note: Nothing to say for the moment
