A Docker container with Raku using the minimalist Linux distro Alpine.
It includes
- Raku (Rakudo - NQP - MoarVM), latest version, as well as older versions in tags/subdirectories
zef
for module installation- Linenoise for easy shell use.
curl
which is needed for some other downstream compatibilities.gcc
andmusl-dev
, which you probably don't need, but can be used for NativeCall-related builds.- User
raku
is defined from version 2020.07, and the Raku process is run as a non-privileged user.
New images should be automatically available at the Docker hub.
Please note that
wget
is installed by default in Alpine, but has some known issues. Usecurl
whenever possible.
Use
docker run -it jjmerelo/alpine-raku
to get into the perl6 interpreter REPL. Can also be used as a "binary" this way
docker run -t jjmerelo/alpine-raku -e "say 'hello þor'"
or you can get into the container by running
docker run -it --entrypoint sh -l -c jjmerelo/alpine-raku
You can also run external scripts via the mounted /app
volume. After changing to this directory
docker run -v `pwd`:/app -it jjmerelo/alpine-raku /app/heloþor.p6
This heloþor.p6
is the example provided in this repo, which you should have cloned or downloaded in the usual way. Check out the use of þ. Cool, isn't it? You can use any other directory instead of /app
For instance, we can create a directory this way
docker run --rm -t jjmerelo/alpine-raku -e "mkdir 'p6-app'; say 'p6-app'.IO.absolute;"
This will return
/home/raku/p6-app
And then
docker run -t -v `pwd`:/home/raku/p6-app jjmerelo/alpine-raku /home/raku/p6-app/pell.p6 6
which would return the first 6 Pell numbers. Or
docker run -t -v `pwd`:/home/raku/p6-app jjmerelo/alpine-raku /home/raku/p6-app/horadam.p6 10
which will return the 10 first elements of the Horadam sequence for p=0, q=1, r= 0.25, s=0.75.
Since zef
is installed, you can use it to install new modules. You can do it by getting into the container and running the shell:
docker run -it --entrypoint="/bin/sh" jjmerelo/alpine-raku
and then
zef install Math::Constants
Or directly in a single command
docker run -it --rm --entrypoint=/bin/sh jjmerelo/alpine-raku -c "zef install Math::Sequences"
This overrides the default entrypoint and, instead, runs zef
as a shell command, installing the module within the container.

Contributions, suggestions and patches are welcome. Please go to the GitHub repo
Previous versions of perl6/raku are available also as image tags. For instance, you can do
docker run -t jjmerelo/alpine-raku:2019.07 -e "'hello þor'.say"
to download and/or run the 2019.07 version of this container.
Additionally, a nightly
tag contains a fresh image, built every night from Rakudo HEAD
.
The raku-test
image
can be used directly for tests, no need to build your own based on
this one.
