NAME VM::EC2::REST::subnet

SYNOPSIS

7        use VM::EC2 ':vpc';
8

METHODS

10       These methods manage subnet objects and the routing among them. A VPC
11       may have a single subnet or many, and routing rules determine whether
12       the subnet has access to the internet ("public"), is entirely private,
13       or is connected to a customer gateway device to form a Virtual Private
14       Network (VPN) in which your home network's address space is extended
15       into the Amazon VPC.
16
17       All instances in a VPC are located in one subnet or another. Subnets
18       may be public or private, and are organized in a star topology with a
19       logical router in the middle.
20
21       Although all these methods can be called from VM::EC2 objects, many are
22       more conveniently called from the VM::EC2::VPC object family. This
23       allows for steps that typically follow each other, such as creating a
24       route table and associating it with a subnet, happen automatically. For
25       example, this series of calls creates a VPC with a single subnet,
26       creates an Internet gateway attached to the VPC, associates a new route
27       table with the subnet and then creates a default route from the subnet
28       to the Internet gateway.
29
30        $vpc       = $ec2->create_vpc('10.0.0.0/16')     or die $ec2->error_str;
31        $subnet1   = $vpc->create_subnet('10.0.0.0/24')  or die $vpc->error_str;
32        $gateway   = $vpc->create_internet_gateway       or die $vpc->error_str;
33        $routeTbl  = $subnet->create_route_table         or die $vpc->error_str;
34        $routeTbl->create_route('0.0.0.0/0' => $gateway) or die $vpc->error_str;

41       Unimplemented:
42        (none)
43
44   $subnet = $ec2->create_subnet(-vpc_id=>$id,-cidr_block=>$block)
45       This method creates a new subnet within the given VPC. Pass a VPC
46       object or VPC ID, and a CIDR block string. If successful, the method
47       will return a VM::EC2::VPC::Subnet object.
48
49       Required arguments:
50
51        -vpc_id     A VPC ID or previously-created VM::EC2::VPC object.
52
53        -cidr_block A CIDR block string in the form "xx.xx.xx.xx/xx". The
54                    CIDR address must be within the CIDR block previously
55                    assigned to the VPC, and must not overlap other subnets
56                    in the VPC.
57
58       Optional arguments:
59
60        -availability_zone  The availability zone for the instances launched
61                            within this instance, either an availability zone
62                            name, or a VM::EC2::AvailabilityZone object. If
63                            this is not specified, then AWS chooses a zone for
64                            you automatically.
65
66   $success = $ec2->delete_subnet($subnet_id)
67   $success = $ec2->delete_subnet(-subnet_id=>$id)
68       This method deletes the indicated subnet. It may be called with a
69       single argument consisting of the subnet ID, or a named argument form
70       with the argument -subnet_id.
71
72   @subnets = $ec2->describe_subnets(@subnet_ids)
73   @subnets = $ec2->describe_subnets(\%filters)
74   @subnets = $ec2->describe_subnets(-subnet_id=>$id, -filter   => \%filters)
75       This method returns a list of VM::EC2::VPC::Subnet objects. Called with
76       no arguments, it returns all Subnets (not filtered by VPC Id). Pass a
77       list of subnet IDs or a filter hashref in order to restrict the search.
78
79       Optional arguments:
80
81        -subnet_id     Scalar or arrayref of subnet IDs.
82        -filter        Hashref of filters.
83
84       Available filters are described at
85       http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeSubnets.html
86
87   $success = $ec2->modify_subnet_attribute(-subnet_id => $sub_id,
88       -map_public_ip_on_launch => $boolean)
89       Modifies a subnet attribute.
90
91       Required arguments:
92
93        -subnet_id                 The ID of the subnet to modify.
94
95        -map_public_ip_on_launch   Modifies the public IP addressing behavior for the
96                                   subnet. Specify true to indicate that instances
97                                   launched into the specified subnet should be
98                                   assigned a public IP address. If set to true, the
99                                   instance receives a public IP address only if the
100                                   instance is launched with a single, new network
101                                   interface with the device index of 0.
102
103       Returns true on success.
