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

tags:
description:
- a hash/dictionary of tags to add to the resource; '{"key":"value"}' and '{"key":"value","key":"value"}'
