Label Inheritance

You can use the label inheritance feature, which allows associated resources to automatically inherit labels from the main resource when the main resource’s labels change or when a relationship is established with the associated resources, improving operational efficiency. For example: When binding labels to a UHost instance, its associated cloud disks, elastic network cards, and elastic public IPs will also automatically bind those labels; subsequent newly added associated resources will also automatically inherit the labels.

1. Usage Limits

• For a list of resource types supported by this feature, please refer to Resources Supporting Label Inheritance
• When you enable and set label inheritance rules for associated resources, if the inherited label key has the same name as a label key already existing on the associated resource, the system may overwrite the existing label on the associated resource. For example: If the associated resource is originally bound with the label cost:hangzhou, and the main resource is bound with the label cost:shanghai, and you set a rule that the associated resource can inherit the cost label from the main resource, then the associated resource’s label cost:hangzhou will be overwritten to cost:shanghai.
