NAME ^

VM::JiffyBox - OO-API for JiffyBox Virtual Machine

VERSION ^

version 0.027

SYNOPSIS ^

 ##############################
 # CREATE A CLONE FROM BACKUP #
 ##############################
 
 # stuff we need to know our self
 my $auth_token = $ARGV[0];
 my $box_name   = $ARGV[1];
 my $clone_name = $ARGV[2];
 
 # prepare connection to VM-Server
 my $jiffy = VM::JiffyBox->new(token => $auth_token); 
 
 # translate VM-Name (String) to ID (Number)
 my $master_box_id = $jiffy->get_id_from_name($box_name);
 
 say "master_box_id: $master_box_id";
 
 # prepare connection to the VM
 my $master_box = $jiffy->get_vm($master_box_id);
 
 # collect information about the VM
 my $backup_id  = $master_box->get_backups()->{result}->{daily}->{id};
 my $plan_id    = $master_box->get_details()->{result}->{plan}->{id};
 
 say "backup_id: $backup_id";
 say "plan_id: $plan_id";
 
 # create a clone of the VM
 my $clone_box  = $jiffy->create_vm( name     => $clone_name,
                                     planid   => $plan_id,
                                     backupid => $backup_id,
                                   );
 
 # abort if create failed

     # FAIL
     die $jiffy->last->{messages}->[0]->{message};
 }
 
 # wait for the clone to be ready
 do {
     say "waiting for clone to get READY";
     sleep 15; 
 } while (not $clone_box->get_details->{result}->{status} eq 'READY');
 
 # start the clone
 $clone_box->start();

ERROR HANDLING ^

All methods will return 0 on failure, so you can check for this with a simple if on the return value. If you need the error message you can use the cache and look into the attribute last. The form of the message is open. It can contain a simple string, or also a hash. This depends on the kind of error. So if you want to be sure, just use Data::Dumper to print it.

CACHING ^

There are possibilities to take advantage of caching functionality. If you have once called get_details(), the results will be stored in the attribute details_cache.

METHODS (LOGIC) ^

Methods that do not send API requests. They are just needed to prepare the requests internally, e.g. due to the OO-design.

get_vm

Returns an object-ref to an existing virtual machine (VM::JiffyBox::Box). Takes the ID for the virtual machine as first argument.

test_mode

If set to any true value methods related to API-calls will just return information about the parameters it would have used to do the call.

METHODS (API) ^

Methods which are directly related to the official API. A call to such a method will directly lead to an API request to the server.

get_details

Returns hashref with information about the hypervisor and its virtual machines. Takes no arguments.

Results are cached in details_cache.

create_vm

Creates a new virtual machine and returns an object-ref to it (VM::JiffyBox::Box). You can pass any named arguments as described by the official API from JiffyBox, since they will be transformed directly to JSON and sent to the API. This means, what is choosen as argument name, will be sent.

name

The name for the new VM. Needed.

planid

The ID for pricing. Needed.

backupid

Name of the backup-image to take. Needed if you don't use distribution.

distribution

OS for the VM. Needed if you don't use backupid.

password

Please look up the official API-Docs for description. Optinal.

use_sskey

Please look up the official API-Docs for description. Optinal.

metadata

Please look up the official API-Docs for description. Optinal.

There may be more options. Please see the official documentation of JiffyBox.

get_distributions

Get information about available distribution images for the virtual machines. Returns a hashref.

get_plans

Get information about existing plans (pricing). Takes no arguments. Returns a hashref.

get_plan_details

Returns details for a plan-id or name (pricing model). Pass name or ID as an argument to the method. Returns a hashref.

METHODS (SHORTCUTS) ^

Methods which are not part of the official API, but provide some often needed calls by using the API mentioned above.

get_id_from_name

Returns the ID for a specific virtual machine. Takes the name for the virtual machine as first argument. Returns 0 if there was no match.

(Also updates the details_cache)

SPECIAL NOTES ^

This software was developed together with an apprentice. This is mentioned here to show that this can lead to good modules and encourage programmers to give interesting work to those who are learning.
