This project is the source for the Docker Library official perl images, which builds the officially-supported perl versions (perlpolicy) on the officially supported Debian base images for several architectures. These are reviewed and built by Docker Library.
The structure of this repo is to use the full version ID of each Perl version, plus a comma separate list of extensions, followed by the Debian release codename that the resulting Docker image will be based from.
The Docker Perl image now builds and runs in architectures other than
amd64, such as i386 and arm64v8; see
docker-library/official-images for the details.
The individual Dockerfiles are generated via generate.pl, which uses
Releases.yaml to populate the individual files. This needs the
Devel::PatchPerl and YAML::XS modules, which you can install by
doing cpanm --installdeps . in this repository's root directory.
To regenerate the Dockerfiles, just run ./generate.pl. Do note that
this might take time as it will download the Perl source tarballs for
each version to re-patch with updates from Devel::PatchPerl as needed.
Also, it is advised to update Devel::PatchPerl as soon as a new
version comes out.
For older versions of Perl, some patches may be necessary to build properly on a current base OS. In those cases, perl -V will show the locally applied patches. These changes should be limited to Configure rather than to code itself, and will be a cherry pick or back port of a patch from the mainline perl branch whenever possible.
