This document describes how to configure custom policies in Tencent Kubernetes Engine (TKE) and grant sub-accounts specific permissions. Reference this document to create custom policies that best fit your business requirements.

Policy Syntax Description

The following figure shows the structure of the policy syntax.


action: indicates an API.
resource: indicates a resource.
Note:
You can define the policy syntax on your own, or create a custom policy by using the policy generator in CAM. You can configure a custom policy based on the following example.
Configuring a Sub-account's Administrative Permissions for a Single TKE Cluster
Use tags to grant full permissions for a batch of clusters to a sub-account
