Basic example:

$ docker pull jmmills/devel-repl
$ docker run -t -i --rm jmmills/devel-repl
$ my $a = [ 'one', 'two', 'three' ]
$ARRAY1 = [
            'one',
            'two',
            'three'
          ];

Or, maybe you want a custom repl.rc and some modules install?

No problem, use a volume to your .re.pl directory and commit your modified container where $container is the docker container ID (also hostname in most cases)

$ docker run -t -i -v $HOME/.re.pl:/.re.pl jmmills/devel-repl
$ shell
root@$container:/# cpanm Acme
...
root@$container:/# exit
$ use Acme
Took 0.00755095481872559 seconds.

Now commit your container in a different shell with a nice shorthand container name.

$ docker commit $container re.pl
# you can kill you state container
$ docker kill $container
$ docker run -i -t --rm re.pl
$ use Acme 
Took 0.009613037109375 seconds.
$ exit

Maybe be like me and setup a re.pl alias so when sandboxing you are always in a container.

$ alias re.pl='docker run -i -t --rm -v $HOME/.re.pl:/.re.pl jmmills/devel-repl'
$ re.pl
$ 1 + 1 Took 0.00048518180847168 seconds.
2
$ exit

Or another way, extend the original image as your own sandbox build

$ cat Dockerfile 
FROM jmmills/devel-repl 
RUN cpanm Acme 
ENTRYPOINT ["/usr/local/bin/re.pl"] 
CMD [""]
$ docker build -t re.pl .
$ docker run -i -t --rm re.pl
$ use Acme
Took 0.00991296768188477 seconds.
$ exit
