module: ec2_tag
short_description: create and remove tag(s) to ec2 resources.
description:
- Creates, removes and lists tags from any EC2 resource. The resource is referenced by its resource id (e.g. an instance being i-XXXXXXX). It is designed to be used with complex args (tags), see the examples. This module has a dependency on python-boto.
version_added: "1.3"
options:
resource:
description:
- The EC2 resource id.
required: true
default: null
aliases: []
state:
description:
- Whether the tags should be present or absent on the resource. Use list to interrogate the tags of an instance.
required: false
default: present
choices: ['present', 'absent', 'list']
aliases: []
region:
description:
- region in which the resource exists.
required: false
default: null
aliases: ['aws_region', 'ec2_region']

# Note: this module needs to be made idempotent. Possible solution is to use resource tags with the volumes.
# if state=present and it doesn't exist, create, tag and attach.
# Check for state by looking for volume attachment with tag (and against block device mapping?).
# Would personally like to revisit this in May when Eucalyptus also has tagging support (3.3).
