@t = $ec2->describe_tags(-filter=>\%filters);

Return a series of VM::EC2::Tag objects, each describing an AMI. A single optional -filter argument is allowed.

Available filters are: key, resource-id, resource-type and value. See http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeTags.html

$bool = $ec2->create_tags(-resource_id=>\@ids,-tag=>{key1=>value1...})

Tags the resource indicated by -resource_id with the tag(s) in in the hashref indicated by -tag. You may specify a single resource by passing a scalar resourceId to -resource_id, or multiple resources using an anonymous array. Returns a true value if tagging was successful.

The method name "add_tags()" is an alias for create_tags().

You may find it more convenient to tag an object retrieved with any of the describe() methods using the built-in add_tags() method:

 @snap = $ec2->describe_snapshots(-filter=>{status=>'completed'});
 foreach (@snap) {$_->add_tags(ReadyToUse => 'true')}

but if there are many snapshots to tag simultaneously, this will be faster:

 @snap = $ec2->describe_snapshots(-filter=>{status=>'completed'});
 $ec2->add_tags(-resource_id=>\@snap,-tag=>{ReadyToUse=>'true'});

Note that you can tag volumes, snapshots and images owned by other people. Only you will be able to see these tags.

$bool = $ec2->delete_tags(-resource_id=>$id1,-tag=>{key1=>value1...})

Delete the indicated tags from the indicated resource. Pass an arrayref to operate on several resources at once. The tag syntax is a bit tricky. Use a value of undef to delete the tag unconditionally:

 -tag => { Role => undef }    # deletes any Role tag

Any scalar value will cause the tag to be deleted only if its value exactly matches the specified value:

 -tag => { Role => 'Server' }  # only delete the Role tag
                               # if it currently has the value "Server"

An empty string value ('') will only delete the tag if its value is an empty string, which is probably not what you want.

Pass an array reference of tag names to delete each of the tag names unconditionally (same as passing a value of undef):

 $ec2->delete_tags(['Name','Role','Description']);

You may find it more convenient to delete tags from objects using their delete_tags() method:

 @snap = $ec2->describe_snapshots(-filter=>{status=>'completed'});
 foreach (@snap) {$_->delete_tags(Role => undef)}

@arguments = $ec2->tagcreate_parm(\%args)

@arguments = $ec2->tagdelete_parm(\%args)
