METHODS

10       These methods allow you to request spot instances and manipulate spot
11       data feed subscriptions.
12
13       Implemented:
14        CancelSpotInstanceRequests
15        CreateSpotDatafeedSubscription
16        DeleteSpotDatafeedSubscription
17        DescribeSpotDatafeedSubscription
18        DescribeSpotInstanceRequests
19        DescribeSpotPriceHistory
20        RequestSpotInstances
21
22       Unimplemented:
23        (none)
24
25   $subscription = $ec2->create_spot_datafeed_subscription($bucket,$prefix)
26       This method creates a spot datafeed subscription. Provide the method
27       with the name of an S3 bucket associated with your account, and a
28       prefix to be appended to the files written by the datafeed. Spot
29       instance usage logs will be written into the requested bucket, and
30       prefixed with the desired prefix.
31
32       If no prefix is specified, it defaults to "SPOT_DATAFEED_";
33
34       On success, a VM::EC2::Spot::DatafeedSubscription object is returned;
35
36       Only one datafeed is allowed per account;
37
38   $boolean = $ec2->delete_spot_datafeed_subscription()
39       This method delete's the current account's spot datafeed subscription,
40       if any. It takes no arguments.
41
42       On success, it returns true.
43
44   $subscription = $ec2->describe_spot_datafeed_subscription()
45       This method describes the current account's spot datafeed subscription,
46       if any. It takes no arguments.
47
48       On success, a VM::EC2::Spot::DatafeedSubscription object is returned;
49
50   @spot_price_history = $ec2->describe_spot_price_history(@filters)
51       This method applies the specified filters to spot instances and returns
52       a list of instances, timestamps and their price at the indicated time.
53       Each spot price history point is represented as a
54       VM::EC2::Spot::PriceHistory object.
55
56       Option arguments are:
57
58        -start_time      Start date and time of the desired history
59                         data, in the form yyyy-mm-ddThh:mm:ss (GMT).
60                         The Perl DateTime module provides a convenient
61                         way to create times in this format.
62
63        -end_time        End date and time of the desired history
64                         data.
65
66        -instance_type   The instance type, e.g. "m1.small", can be
67                         a scalar value or an arrayref.
68
69        -product_description  The product description. One of "Linux/UNIX",
70                         "SUSE Linux"  or "Windows". Can be a scalar value
71                         or an arrayref.
72
73        -availability_zone A single availability zone, such as "us-east-1a".
74
75        -max_results     Maximum number of rows to return in a single
76                         call.
77
78        -next_token      Specifies the next set of results to return; used
79                         internally.
80
81        -filter          Hashref containing additional filters to apply,
82
83       The following filters are recognized: "instance-type", "product-
84       description", "spot-price", "timestamp", "availability-zone". The '*'
85       and '?' wildcards can be used in filter values, but numeric comparison
86       operations are not supported by the Amazon API. Note that wildcards are
87       not generally allowed in the standard options. Hence if you wish to get
88       spot price history in all availability zones in us-east, this will
89       work:
90
91        $ec2->describe_spot_price_history(-filter=>{'availability-zone'=>'us-east*'})
92
93       but this will return an invalid parameter error:
94
95        $ec2->describe_spot_price_history(-availability_zone=>'us-east*')
96
97       If you specify -max_results, then the list of history objects returned
98       may not represent the complete result set. In this case, the method
99       more_spot_prices() will return true. You can then call
100       describe_spot_price_history() repeatedly with no arguments in order to
101       retrieve the remainder of the results. When there are no more results,
102       more_spot_prices() will return false.
103
104        my @results = $ec2->describe_spot_price_history(-max_results       => 20,
105                                                        -instance_type     => 'm1.small',
106                                                        -availability_zone => 'us-east*',
107                                                        -product_description=>'Linux/UNIX');
108        print_history(\@results);
109        while ($ec2->more_spot_prices) {
110           @results = $ec2->describe_spot_price_history
111           print_history(\@results);
112        }
113
114   @requests = $ec2->request_spot_instances(%args)
115       This method will request one or more spot instances to be launched when
116       the current spot instance run-hour price drops below a preset value and
117       terminated when the spot instance run-hour price exceeds the value.
118
119       On success, will return a series of VM::EC2::Spot::InstanceRequest
120       objects, one for each instance specified in -instance_count.
121
122       Required arguments:
123             -spot_price        The desired spot price, in USD.
124
125             -image_id          ID of an AMI to launch
126
127             -instance_type     Type of the instance(s) to launch, such as "m1.small"
128
129       Optional arguments:
130             -instance_count    Maximum number of instances to launch (default 1)
131
132             -type              Spot instance request type; one of "one-time" or "persistent"
133
134             -valid_from        Date/time the request becomes effective, in format
135                                  yyyy-mm-ddThh:mm:ss. Default is immediately.
136
137             -valid_until       Date/time the request expires, in format
138                                  yyyy-mm-ddThh:mm:ss. Default is to remain in
139                                  effect indefinitely.
140
141             -launch_group      Name of the launch group. Instances in the same
142                                  launch group are started and terminated together.
143                                  Default is to launch instances independently.

146                                  the same zone group name will be launched into the
147                                  same availability zone. This is independent of
148                                  the -availability_zone argument, which specifies
149                                  a particular availability zone.

160                                encode this. It will be done for you.
161
162             -availability_zone The availability zone you want to launch the
163                                instance into. Call $ec2->regions for a list.
164             -zone              Short version of -availability_aone.
165
166             -placement_group   An existing placement group to launch the
167                                instance into. Applicable to cluster instances

175
176             -ramdisk_id        ID of the ramdisk to use for the instances,
177                                overriding the ramdisk specified in the image.

182
183             -block_device_mapping  Alias for -block_devices.
184
185             -network_interfaces  Same as the -network_interfaces option in run_instances().

208       instances that are already running as a result of the requests. It
209       returns a list of VM::EC2::Spot::InstanceRequest objects, whose fields
210       will be unpopulated except for spotInstanceRequestId and state.

215   @requests =
216       $ec2->describe_spot_instance_requests(-spot_instance_request_id=>\@ids,-filter=>\%filters)
217       This method will return information about current spot instance
218       requests as a list of VM::EC2::Spot::InstanceRequest objects.
