Dealing with perl applications deployment, which I do with chef - modern open source platform for configuration, I have written psgi cookbook to configure, install psgi applications. Here are some simple exmaples of usage which are self explanatory.

This snippet of code install Catalyst application as fast cgi standalone server:

psgi_application 'Catalyst FCGI application' do
    operator      'Dancer'
    application_user    'user'
    application_home    '/home/user/app/'
    script              '/home/user/app/scripts/foo.psgi'
    config              '/home/user/app/app.conf'
    action              'install'      
end

And this snippet of code installs Dancer application as Starman web server:

psgi_application 'Dancer Starman application' do
    operator                 'Dancer'
    server                     'Starman'
    port                        '5010'
    application_user    'user'
    application_home    '/home/user/app/'
    script              '/home/user/app/scripts/foo.psgi'
    action              'install'      
end

I love the idea of pinto, so decided to contribute in some way. So there is pinto cookbook - a chef cookbook to install and configures pinto applications. I hope this cookbook will be useful for pinto users and developers.

]]> perl distributive "early" testing with jenkins tag:blogs.perl.org,2013:/users/melezhik//1336.4446 2013-03-18T05:58:03Z 2013-03-18T06:53:01Z Often when deploying application one may face the risk of divergence between testing and production environment.

Even though you have a stage servers `like production one', it'd be reasonable to check distributive in production environment before release is happened. I would call it `early` testing. Yes, of course, some subtle bugs will arise only in runtime phase, and unit test cannot cover it all, I say here about prerequisite unmet issues. In perl world unit tests and prerequisites checks are executed in standart way. One follows standard procedure, when installing things.

I put here example for Module::Build based project, but with ExtUtils::MakeMaker it's almost the same: 

perl Build.PL # check dependencies and generate build file
./Build 
./Build test # run unit tests

So, why not to automate this process in continues integration approach, like for example Jenkins does?

  1. Upload distributive to production server
  2. Unpack it
  3. Run standard perl Build.PL/Makefile.PL cycle to execute unit tests and check prerequisites
  4. If anything goes wrong you know it in good time, before release is happened!

So this is what I've done in jenkins perl-smoke-test plugin. Please check it out and try to use it!

One of it's great features - one may extend it by writing custom plug-ins. Recently I have create one plug-in to build and make distributive of perl applications. It implements standard build... melezhik https://github.com/melezhik
It implements standard build scheme:
  1. look up source directory
  2. install dependencies into local directory
  3. create distributive

Other features are:
  1. find 'tagged' directory with maximum version number ( implementing install from subversion tags )
  2. applying different patches (install other cpan modules)
  3. color output
  4. ... and some others

For now it's only Module::Build compatible.

I have created cpan cookbook to install cpan modules with chef. It's easy in use, because all the implimenation is hidden providing you simple interface:

cpan_client 'CGI' do
    action 'install'
    install_type 'cpan_module'
    user 'root'
    group 'root'

end

Among cpan_client features are:

  • installing in dry-run mode
  • installing with given installbase and installpath
  • installing from tarball
  • installing within given cwd
  • and others
