When using Tencent Smart Advisor-Chaotic Fault Generator (CFG), you may encounter various scenarios that require service authorization to access related cloud resources. Each scenario usually corresponds to the preset policies contained in different roles, mainly involving the CFG_QCSLinkedRoleInChaos role. This document will show the details of the authorization policy, authorization scenarios, and authorization steps.
Role Permissions (CFG_QCSLinkedRoleInChaos)
After you activate the CFG service, Tencent Cloud will grant your account CFG_QCSLinkedRoleInChaos role permission. This service role is associated with multiple preset policies by default. To obtain relevant permissions, it is necessary to execute the corresponding preset policy authorization operation in specific authorization scenarios. After the operation is completed, the corresponding policy will appear in the list of authorization policies for the role. The CFG_QCSLinkedRoleInChaos preset policy associated with the role includes the access permissions for the CFG service to cloud resources.
Preset Policies (QcloudAccessForCFGLinkedRoleInChaos)
Authorization Scenarios
After you register and log in to Tencent Cloud and log in to CFG Console for the first time, you need to go to Cloud Access Management page to grant current account the permissions for the CFG service to operate cloud resources such as Cloud Virtual Machine (CVM), Load Balancing (CLB), TencentCloud Automation Tools (TAT), Elastic Cache Redis (Redis), TencentDB for MySQL (CDB), Tencent Cloud Observability Platform (Monitor), and Virtual Private Cloud (VPC).
Authorization Steps
1. Log in to the CFG Console, select Experiment Management in the left sidebar, and the Service Authorization window will pop up.
2. Click Go to Authorize to enter the Role Management page.
3. Click Agree to Authorize, and after the identity verification is completed, the authorization will be successfully granted.
