This project is the source for the Docker perl repo; for more details, take a look at https://registry.hub.docker.com/_/perl/.
The structure of this repo is to use the full version ID of each Perl version, plus a comma separate list of extensions. Every directory is expected to have at least the bit specification (32bit or 64bit), and at the moment the only other extension is threaded.
Despite having a directory layout expressed in terms of bit
specifications as above, the Docker Perl image now builds and runs in
architectures other than
amd64, such as
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
YAML::XS modules, which you can install by
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.
