Set PERL5LIB to /usr/lib in perl/stretch-slim (maybe others)

[JJ]

I have been figtingh with this image for long time, to eventually discover that, first, some modules available in the latest couldn't be installed here, and second, that when I installed them using default debian packages, they were not available to Perl. That's probably a feature of the perl version you are installing, and I know you can define env variables when running a Docker image, but since /usr/lib is the default place for installing system-wide modules, would it be possible to have it somehow built-in so that it's used from all Perl scripts?

Hi @JJ, thanks for the report!

This is basically the same as #26 (for the case of installing CPAN modules via Debian packages) but I'm curious as to what particular modules you're having difficulty installing here; I take that you're using cpanm as well to install those latest modules?

Note that by default, docker-perl installs CPAN modules to -Dsiteprefix, which is usually in /usr/local/lib/perl5/site_perl/5.XX.X.

Some lwp::simple deps such as html::entities and HTML::tagset. It's in my jmerelo/iv-test image El mié., 19 sept. 2018 18:48, Zak B. Elep <notifications@github.com> escribió:

I suppose it is this image Dockerfile? If so, I think you'll need a few things here:

• since you're using perl:slim, you'll need to install the build toolchain gang such as gcc, make, and libc6-dev
• once the above are installed, you can now cpanm LWP::Simple <other CPAN deps>
• I recommend listing your module dependencies in a cpanfile so that your module installation can simply become cpanm --installdeps ., instead of having to list these directly in the Dockerfile

Putting that all together, your Dockerfile might become like this:

FROM perl:5.28-slim

WORKDIR /test

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
       gcc make libc6-dev \
    && cpanm Test::More Test::Harness Git File::Slurper \
       JSON Net::Ping TAP::Formatter::Color Term::ANSIColor \
       LWP::Simple

VOLUME /test

ENTRYPOINT ['/usr/local/bin/prove', '-c']

I'm able to install those modules listed above into the resulting image; if there are other dependencies, let me know so I can test as well.

Right

- since you're using perl:slim, you'll need to install the build toolchain gang such as gcc, make, and libc6-dev - once the above are installed, you can now cpanm LWP::Simple <other CPAN deps> - I recommend listing your module dependencies in a cpanfile <https://metacpan.org/pod/cpanfile> so that your module installation can simply become cpanm --installdeps ., instead of having to list these directly in the Dockerfile Putting that all together, your Dockerfile might become like this: FROM perl:5.28-slim WORKDIR /test RUN apt-get update \ && apt-get install -y --no-install-recommends \ gcc make libc6-dev \ && cpanm Test::More Test::Harness Git File::Slurper \ JSON Net::Ping TAP::Formatter::Color Term::ANSIColor \ LWP::Simple VOLUME /test ENTRYPOINT ['/usr/local/bin/prove', '-c'] I'm able to install those modules listed above into the resulting image; if there are other dependencies, let me know so I can test as well. — You are receiving this because you were mentioned.

That's great. Thanks!

It seems this is now resolved? I'll close this for now; feel free to re-open if needed.
