scratchy

Quickly bootstrap a Linux distro in a (non-Docker) container and interactively execute something in it.

Note: this is early stage and automatic bootstrapping only supports ArchLinux as of now.

Installation

From Source

Make sure you have a working Go environment (Go 1.11 or higher is required). See the install instructions.

Compiling scratchy is easy, simply run:

git clone https://github.com/muesli/scratchy.git
cd scratchy
go build

Usage

Bootstrap a new base ArchLinux install into a directory: (make sure package arch-install-scripts is installed on your host!)

$ sudo scratchy bootstrap /some/root

Bootstrapping arch: /some/root
==> Creating install root at /some/root
==> Installing packages to /some/root

...

Successfully bootstrapped root: /some/root

Start a bash shell inside the container:

$ sudo scratchy run /some/root /bin/bash

Copying /etc/resolv.conf to /some/root/etc/resolv.conf
Executing in container (/some/root): /bin/bash
[root@container /]#

Start with a specific uid/gid inside container:

$ sudo scratchy -uid 1000 -gid 1000 run /some/root /bin/ps ax

Executing in container (/some/root): /bin/ps ax
