    Image Search:Manage instance tags

    Last Updated:Aug 23, 2023

    This topic describes how to manage instance tags to help you classify instances by tag.

    Limits

    Each tag is a key-value pair. Tags have the following limits:

    • Each tag must be attached to an Image Search instance.

    • You can attach up to 20 tags to an instance. Tag names are case-sensitive.

    • The tag keys that are attached to an instance must be unique. If you create a tag whose key is already used, the new tag overwrites the existing tag that uses the same key.

    • If an instance is deleted, the tags that are attached to the instance are deleted.

    • Consider the following limits when you create a tag:

      • The key is required and can be up to 64 characters in length. The key cannot start with aliyun or acs:, or contain http:// or https://. We recommend that you keep the key short.

      • The value is optional and can be up to 128 characters in length. It cannot start with aliyun or acs:, or contain http:// or https://. We recommend that you keep the value short.
