NAME

Server::Module::Comparison - check perl module versions installed on servers.

VERSION

version 0.012

SYNOPSIS

Gets versions of perl modules on servers.

    my $comparer = Server::Module::Comparison->new({
         perl_path => '/opt/perl5/bin',
         modules => [qw/OpusVL::CMS OpusVL::FB11X::CMSView OpusVL::FB11X::CMS/]
     });
    my $versions = $comparer->check_container('quay.io/opusvl/prem-website:staging');


    my $comparer = Server::Module::Comparison::FromModuleList(
        'modules.txt',
        { perl_path => '/opt/perl5/bin/' }
    );

DESCRIPTION

A module for checking which versions of a particular list of perl modules are installed on a server.

This relies on mversion (Module::Version) being installed on the server to make querying the module version numbers simple.

This module uses system and isn't expected to defend against malicous input at all. It is designed as a quick and simple developer tool.

METHODS

FromModuleList

Createa a new Server::Module::Comparison object from a line delimited list of modules.

check_container

Run mversion in a docker container.

    my $versions = $comparer->check_container('quay.io/user/some-website:staging');

This is done by running the container locally. It does not try to pull the container. It is assumed you have access to docker and the correct image to hand.

check_ssh_server

Checks modules via ssh.

check_local

Checks modules locally.

check_correct_guess

This takes a string and guesses whether to assume it's a container identifier or an ssh server.

Also supports a docker:// or ssh:// type uri scheme to help identify the server being identified.

ATTRIBUTES

perl_path

Location of perl (and therefore also where mversion will be installed). Set this if you have your perl installed in a non default location not on the path. We have ours installed to /opt/perl5/bin for example.

modules

The list of modules to check. This is an array ref.
