Overview

Scenario

Tags can be used to identify private CAs and private certificates. You can use tags to group and centrally manage private CAs and private certificates by usage, owner, or environment.

Tag Naming Rules

• Each tag consists of a key-value pair.
• A maximum of 20 tags can be added to each private CA or private certificate.
• For each resource, a tag key must be unique and can have only one tag value.
• A tag consists of a tag key and a tag value. The naming rules are listed in Table 1.
  

  If your organization has configured a tag policy for the CCM service, you need to add tags to private CA or private CAs based on the tag policy. Otherwise, the tagging operation might fail. For more information about the tag policy, contact your organization administrator.
