DESCRIPTION

This object supports the EC2 Virtual Private Cloud subnet interface. Please see VM::EC2::Generic for methods shared by all VM::EC2 objects.

METHODS

These object methods are supported:

            

              
              
subnetId   -- the ID of the subnet
state      -- The current state of the subnet, either "pending" or "available"
vpcId      -- The ID of the VPC the subnet is in.
cidrBlock  -- The CIDR block assigned to the subnet.
availableIpAddressCount -- The number of unused IP addresses in the subnet.
availableZone -- This subnet's availability zone.
defaultForAz  -- Indicates if this is the default subnet for the Availability Zone
mapPublicIpOnLaunch -- Indicates if instances launched in this subnet automatically receive a
                       public IP address
            
          

This class supports the VM::EC2 tagging interface. See VM::EC2::Generic for information.

In addition, this object supports the following convenience methods:

            

              
              
vpc()                -- Return the associated VM::EC2::VPC object.
zone()               -- Return the associated VM::EC2::AvailabilityZone object.
refresh()            -- Refreshes the object from its current state in EC2.
current_state()      -- Refreshes the object and returns its current state.
create_route_table() -- Create a new route table, associates it with this subnet, and
                        returns the corresponding VM::EC2::VPC::RouteTable
                        object.
associate_route_table($table)
                     -- Associates a route table with this subnet, returning true if
                        sucessful.
disassociate_route_table($table)
                     -- Removes the association of a route table with this subnet. Produces
                        a fatal error if $table is not associated with the subnet. Returns true
                        on success.
associate_network_acl($network_acl_id)
                     -- Associates a network ACL with this subnet, returning the new
                        association ID on success.
disassociate_network_acl()
                     -- Removes the association of a network ACL with this subnet. The subnet
                        will then be associated with the default network ACL.  Returns the
                        the association ID.
            
          

STRING OVERLOADING

When used in a string context, this object will be interpolated as the subnet ID.
