The Perl platform supports Perl 5.18.2 (on Ubuntu 14.04 LTS) or Perl 5.22.1 (on Ubuntu 16.04 LTS).

If you just run a tsuru app deploy of your code, tsuru will try to download all of your depencies using cpanfile or cpanfile.snapshot.

There are two ways to list the applications dependencies: cpanfile or cpanfile.snapshot. The priority order is: cpanfile.snapshot -> cpanfile. The file should be in the root of deploy files.

You can define a file called cpanfile that list all CPAN dependencies of your application, each line represents one dependency, here's an example:

$ cat cpanfile
requires 'Mojolicious';

After invokin tsuru app deploy, tsuru will receive your code and tell the platform to install all the depencies using carton install --cached --deployment.
