DESCRIPTION

27       This module queries Amazon's Elastic Compute Cloud Metadata service
28       described at:
29       http://docs.amazonwebservices.com/AWSEC2/2007-08-29/DeveloperGuide/AESDG-chapter-instancedata.html
30       . It also fetches 'user_data' which follows the same API but is often
31       no considered part of the metadata service by Amazons documentation.
32       The module also ships with a command line tool ec2meta  that provides
33       the same data.
34
35       THIS MODULE WILL ONLY WORK ON AN EC2 INSTANCE.
36

METHODS

38   new()
39       A constructor - for convenience all methods are class methods.
40
41   all_data()
42       Returns a hash ref of all the keys, and their values. Note: this means
43       that public_keys is a listing of the keys not a listing of the values.
44
45   available_data()
46       A listing of all the meta_data and user_data available from this
47       module.
48
49       ami_id
50       ami_manifest_path
51       ami_launch_index
52       ancestor_ami_ids
53       instance_id
54       instance_type
55       kernel_id
56       ramdisk_id
57       placement
58       block_device_mapping
59       local_hostname
60       public_hostname
61       local_ipv4
62       public_ipv4
63       reservation_id
64       security_groups
65       product_codes
66       user_data
67           These methods all return the verbatim data from the calls to the
68           service, and take no parameters.
69
70       public_keys($key)
71       public_key($key)
72           Lists public keys if no key given, returns content of key if a key
73           is given.
