如何通过Amazon EC2 API修改实例的“Name”属性？

Question

I'd like to be able to create/modify the 'Name' attribute of an EC2 instance, ie, the field shown by 'Name' in the web UI.

I am quite comfortable spawning instances via the Amazon API, however I cannot find any references to instance naming in the API reference . How can I create an instance with the Name attribute set, or modify the Name of an existing instance?

The Name attribute is just a regular tag, that happens to be available/used by default for many resources, including Amazon EC2 instances.

Accordingly, you can change it eg via the Amazon EC2 API Tools (ec2-create-tags, ec2-describe-tags, ec2-delete-tags), which facilitate the respective APIs in turn, see section API within Using Tags for more details:

Summary of available API actions:

• CreateTags — Adds a set of tags to a set of resources. You also use this to update a tag's value (overwrites the existing value). [emphasis mine]

• DeleteTags — Deletes a set of tags from a set of resources.

• DescribeTags — Lists your tags, or just certain ones you specify.

These actions are further detailed in the Amazon Elastic Compute Cloud API Reference as usual:

• CreateTags
• DescribeTags
• DeleteTags
