Perl Application Hosting
Want a Dancer application backed by MySQL? Or maybe you’re looking for Mojolicious and MongoDB? OpenShift Online currently supports Perl 5.10.
Perl is a high-level, general-purpose dynamic programming language. With OpenShift you can easily deploy and run Perl applications using your favorite frameworks and databases.
Simplify Your Perl Deployments
Getting a Perl app with a MySQL backend deployed onto OpenShift is as easy as executing two commands:
$ rhc app create MyApp perl-5.10
$ rhc cartridge add mysql-5.5 -a MyAppThese two commands create your gear and install and configure Perl, MySQL, and a git repository. You can now visit your application on the web at:
http://MyApp-MyDomain.rhcloud.com/The Perl Cartridge
The perl cartridge provides Perl on OpenShift.
Template Repository Layout
index.pl
.openshift/ Location for OpenShift specific files
action_hooks/ See the Action Hooks documentation (1)
markers/ See the Markers section below
cpan.txt List of modules to install| 1 | Action Hooks documentation |
Due to changes in Perl cartridge template layout, the application root is now stored in $OPENSHIFT_REPO_DIR, but is also backward compatible with deprecated perl/ directory.
Modules are installed with cpan.txt, located in the .openshift/ directory. In addition, application dependencies can be installed using cpanfile or Makefile.PL placed in the .openshift/ folder. deplist.txt is deprecated in favor of .openshift/cpan.txt.
Cartridge Layout
run/ Various run configs (like httpd pid)
usr/ Perl example application template
env/ Environment variables
logs/ Log data (like httpd access/error logs)
lib/ Various libraries
bin/setup The script to setup the cartridge
bin/build Default build script
bin/teardown Called at cartridge destruction
bin/control Init script to start/stop httpd
versions/ Version data to support multiple perl versions (copied into place by setup)Markers
Adding marker files to .openshift/markers will have the following effects:
| Marker | Effect |
|---|---|
force_clean_build |
Will remove all previous perl deps and start installing required deps from scratch |
enable_cpan_tests |
Will install all the cpan packages and run their tests |
hot_deploy |
Will prevent the apache process from being restarted during build/deployment |
disable_auto_scaling |
Will prevent scalable applications from scaling up or down according to application load. |
enable_public_server_status |
Will enable server-status application path to be publicly available. |
