NAME PITA::Image - PITA Guest Manager for inside system images SYNOPSIS A typical startup script #!/usr/bin/perl use strict; use IPC::Run3; use PITA::Image; # Wrap the main actions in an eval to catch errors eval { # Configure the image manager my $manager = PITA::Image->new( injector => '/mnt/hbd1', workarea => '/tmp', ); $manager->add_platform( scheme => 'perl5', path => '', # Default system Perl ); $manager->add_platform( scheme => 'perl5', path => '/opt/perl5-6-1/bin/perl' ); # Run the tasks $manager->run; # Report the results $manager->report; }; # Shut down the computer on completion or failure run3( [ 'shutdown', '-h', '0' ], \undef ); exit(0); And a typical configuration image.conf class=PITA::Image version=0.10 support=http://10.0.2.2/ [ task ] task=Test scheme=perl5.make path=/usr/bin/perl request=request-512311.conf DESCRIPTION While most of the PITA system exists outside the guest images and tries to have as little interaction with them as possible, there is one part that needs to be run from inside it. The "PITA::Image" class lives inside the image and has the responsibility of accepting the injector directory at startup, executing the requested tasks, and then shutting down the (virtual) computer. Setting up a Testing Image Each image that will be set up will require a bit of customization, as the entire point of this type of testing is that every environment is different. However, by keeping most of the functionality in the "PITA::Image" and PITA::Scheme classes, all you should need to do is to arrange for a relatively simple Perl script to be launched, that feeds some initial configuration to to a new "PITA::Image" object. And it should do the rest. METHODS new my $manager = PITA::Image->new( injector => '/mnt/hdb1', workarea => '/tmp', ); The "new" creates a new image manager. It takes two named parameters. injector The required "injector" param is a platform-specific path to the root of the already-mounted /dev/hdb1 partition (or the equivalent on your operating system). The image configuration is expected to exist at image.conf within this directory. workarea The optional "workarea" param provides a directory writable by the current user that can be used to hold any files and do any processing in during the running of the image tasks. If you do not provide a value, "File::Temp::tempdir()" will be used to find a default usable directory. Returns a new "PITA::Image" object, or dies on error.
