Authorizing by using custom policies

Last updated: 2024-12-11 18:50:30
    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 TKE API Permissions

    This section describes multiple features, their sub-features, corresponding Tencent Cloud APIs, APIs for indirect calls, resource levels for permission control, and Action fields of clusters and node modules.
