NAME

DigitalOcean - An OO interface to the Digital Ocean API.

VERSION

Version 0.13

SYNOPSIS

This module is an object oriented interface into the Digital Ocean API.

    use DigitalOcean;

    #for more efficient use, remove "wait_on_events => 1". See WAITING ON EVENTS section for more info
    my $do = DigitalOcean->new(client_id=> $client_id, api_key => $api_key, wait_on_events => 1);

    for my $droplet (@{$do->droplets}) { 
        print "Droplet " . $droplet->name . " has id " . $droplet->id . "\n";
    }

    my $droplet = $do->droplet($droplet_id);
    $droplet->reboot;
    $droplet->power_off;
    $droplet->power_on;
    $droplet->destroy;

    my $new_droplet = $do->create_droplet(
        name => 'new_droplet',
        size_id => $size_id,
        image_id => $image_id,
        region_id => $region_id,
    );

    $new_droplet->enable_backups;

HOW THIS MODULE IS WRITTEN

This module is written to be flexible, so that if changes are made to the Digital Ocean API, then I don't have to update this module every time they make changes so that this module will still work. What I mean by this is that if Digital Ocean adds new parameters that need to be passed into their calls, these parameters can be passed into the current calls even if I don't specify them as options and it should still work. For example, say that for the create_droplet call Digital Ocean adds a new required parameter "timestamp". All you would have to do is pass in timestamp:

    $do->create_droplet(
        name => 'new_droplet',
        size_id => $size_id,
        image_id => $image_id,
        region_id => $region_id,
        timestamp => $timestamp,
    );

And timestamp will be added to the request call with the other parameters. However, if Digital Ocean adds any new attributes to an object, such as droplet_type for DigitalOcean::Droplet, this I will have to add to the DigitalOcean::Droplet in order for the DigitalOcean::Droplet objects to respect this new attribute. If you see that Digital Ocean has added a new attribute that I do not have in one of my objects, please let me know in bugs.

WAITING ON EVENTS

wait_on_events

For some calls in Digital Ocean's API, you need to wait for one call to finish before you can submit another request that depends on the first call. For instance, if you resize a droplet and then want to take a snapshot of the droplet, you must wait until the action of resizing the droplet is complete before you can take the snapshot of this droplet. If you set wait_on_events to 1, then DigitalOcean will wait on every event until it is complete, so this way you do not have to worry about the synchronization of events or if you need to wait between two events. However, turning wait_on_events on for every event can also cause your script to run much slower if you do not need to be waiting on every event.

You may wait on all events by passing in wait_on_events when you create the DigitalOcean object:

    my $do = DigitalOcean->new(client_id=> $client_id, api_key => $api_key, wait_on_events => 1);

Or you can toggle it after you have created the DigitalOcean object:

    $do->wait_on_events(1);
    $do->wait_on_events(undef);

The default for wait_on_events is that it is set to undef and does not wait on events.

wait_on_event

A more efficient solution is to only wait on indiviudal events that you have to wait on. You can pass in the wait_on_event flag to any subroutine (this includes subroutines in DigitalOcean's sub modules, such as DigitalOcean::Droplet) and DigitalOcean will wait until that call is complete before returning.

    my $droplet = $do->create_droplet(
        name => 'new_droplet',
        size_id => $size_id,
        image_id => $image_id,
        region_id => $region_id,
        wait_on_event => 1,
    );

    $droplet->reboot(wait_on_event => 1);
    $droplet->snapshot(wait_on_event => 1);

    my $domain = $do->domain(56789);
    my $record = $domain->record(98765);

    $record->edit(
        record_type => 'A',
        data => '196.87.89.45',
        wait_on_event => 1,
    );

    etc.

DigitalOcean uses DigitalOcean::Event's wait subroutine to wait on events.

time_between_requests

DigitalOcean uses DigitalOcean::Event's wait subroutine to wait on events. It does this by making requests to Digital Ocean until the event is complete. You can use time_between_requests to determine how long DigitalOcean waits between requests before making another request to Digital Ocean to see if an event is done. You can use it like so:

    $do->time_between_requests(1);

or

    my $do = DigitalOcean->new(client_id=> $client_id, api_key => $api_key, time_between_requests => 1);

An integer value must be passed in. The default is 2.
