Access Management

    Basic CAM Concepts

    A root account authorizes sub-accounts by binding policies. The policy settings can be specific to the level of API, Resource, User/User Group, Allow/Deny, and Condition.


    • Root account: it owns all Tencent Cloud resources and can access any of its resources.
    • Sub-account: it includes sub-users and collaborators.
    • Sub-user: it is created and fully owned by a root account.
    • Collaborator: it has the identity of a root account. After it is added as a collaborator of the current root account, it becomes one of the sub-accounts of the current root account and can switch back to its root account identity.
    • Identity credential: it includes login credentials and access certificates. Login credential refers to a user's login name and password. Access certificate refers to Tencent Cloud API keys (SecretId and SecretKey).

    Resource and permission

    • Resource: it is an object manipulated in Tencent Cloud services. TDMQ for RabbitMQ resources include clusters, vhosts, exchanges, queues, and bindings.
    • Permission: it is an authorization that allows or forbids users to perform certain operations. By default, a root account has full access to all resources under it, while a sub-account does not have access to any resources under its root account.
    • Policy: it is a syntax rule that defines and describes one or more permissions. The root account performs authorization by associating policies with users/user groups.

    List of APIs Supporting Resource-Level Authorization

    TDMQ for RabbitMQ supports resource-level authorization. You can grant a specified sub-account the API permission of a specified resource.

    APIs supporting resource-level authorization include:

    Authorization Scheme Examples

    Full access policy

    Grant a sub-user full access to the TDMQ for RabbitMQ service (for creating, managing, etc.).

    1. Log in to the CAM console.
    2. Click Policy on the left sidebar.
    3. In the policy list, click Create Custom Policy.
    4. In the Select Policy Creation Method pop-up window, select Create by Policy Generator.
    5. On the Edit Policy page, click Import Policy Syntax in the top-right corner.
    6. On the Import Policy Syntax page, search for TDMQ, select QcloudTDMQFullAccess in the search results, and click OK.
    7. On the Edit Policy page, click Next, enter the policy name and description, and select the user/user group you want to associate.
    8. Click Complete.

    Read-Only access policy

    The following uses granting the read-only permission of a cluster as an example.

    1. Log in to the CAM console.
    2. Click Policy on the left sidebar.
    3. In the policy list, click Create Custom Policy.
    4. In the Select Policy Creation Method pop-up window, select Create by Policy Generator and enter the policy information.
    Parameter Description
    Effect Select Allow
    Service Select TDMQ
    Action Select Read operation
    Resource Select Specific resources and click Add six-segment resource description
  • Region: select the resource region
  • Account: it is automatically populated
  • Resource Prefix: clusterId
  • Enter the ID of the cluster you want to authorize
  • Condition Allow access to specified operations only when the request is from the specified IP range
    1. Click Next, enter the policy name and description, and select the user/user group you want to associate.
    2. Click Complete.
