Godl

Godl is a command line tool to quickly create ACI container images out of random data. Here are a few reasons why I wrote it:

Quick Binaries

Godl can be used to quickly package a given binary file on your host into an ACI. It's quick because Godl:

1. Generates a passable Manifest, although you can specify your own.
2. Discover all dynamic libraries (dependencies) similar to ldd and will package them as well.
3. Takes random filename patterns, so you can quickly package entire subdirectories into ACI images.

Complimentary to actool

CoreOS folks have a standard ACI tool, which requires you to manually create rootfs and manifest. Godl can be complimentary to it: use godl to quickly generate RootFS content, inspect it and use actool to build an ACI.

Limitations

1. Godl does not generate ACI signatures.
2. Godl is an awufl name

Usage

USAGE:
    godl [OPTION]... PATTERN PATTERN...

PATTERN
    File(s) or directories to pack into the ACI

OPTIONS:
    -r : output directory which will contain rootfs + manifest (./aci)
    -o : output ACI image (none)
    -t : target directory within rootfs (/)
    -f : force overwrite. (false)
    -m : manifest file to use (auto-generates one if missing)
    -n : application name if manifest is not given
    -n : application description if manifest is not given
    -i : ignore binary dependencies (false)

EXAMPLES:
    godl -o ed.aci /bin/ed
    godl -r dir ../project

It's easy to play with it, using -r option (when it genertes a rootfs directory instead of an ACI) and inspecting it using tree. Also try -t option: it allows you to package a bunch of random files under a given target dir within rootfs.
