Build scripts to build Rakudo/Perl 6 docker images

p6-rakudo-docker

SYNOPSIS

Build scripts to build and manage Rakudo/Perl 6 docker images.

USAGE

./build -v <version> -r [rakudo|rakudo-star]
         [-d <debian_release>] [-f <image_name>] [-t <tag>]

  -r  - Type of rakudo build.
        'rakudo-star' is one of the Rakduo stable releases.
        'rakudo' is one of the monthly builds.
  -v  - Version of Rakudo to build e.g. 2017-06
  -n  - Name to be given to the image. e.g. myfoo/rakudo-star
  -t  - Tag to apply to the image. e.g. latest
  -f  - Parent image (FROM) to use as base
  -d  - Debian release to use. e.g. 'jessie', 'stretch', 'buster', etc
        This chooses an appropriate parent image as well as set the release
        within the container environment.

  e.g.
    $ ./build -r rakudo -v 2017-06
    ...

    $ docker images | grep -iE 'IMAGE ID|rakudo'

DESCRIPTION

These scripts cater to the build and management of a catalogue of Rakudo / Perl 6 docker images of different versions.

./build builds a Rakudo Debian-based docker image with the zef module manager and a few other utilities to make the image usable with Debian (and related) expectations - e.g. beside a regular Debian host install. (Alpine Linux may be cool but it is deficient for non-production use-cases where you often need access to the wider GNU/Linux ecosystem).

As ./build takes a rakudo version to build - it is possible to create/maintain docker images for different versions of Rakudo - making switching between versions trivial. This can be useful in learning, dev/test, etc environments.

./run instantiates a docker instance that is run in the same PID space as the host with appropriate volumes mounted making interactions with the host transparent. i.e. running a containerized rakudo against code on the host is as trivial as

(docker host) $ ./run shalomb/rakudo:2017.06 perl6 $PWD/../path/to/script.p6

TODO

• Manage zef module installations on a shared volume?
