Granting Namespace Permissions to a User or User Group

Configuration Description

• You need to have a cloud account. Only the account and IAM users who have been assigned the CCIFullAccess policy or all RBAC policies can grant permissions to other users.
• In this example, both a user group and a user are granted permissions to access namespaced resources. You have the choice to grant permissions to either users or user groups.
• You can use the process flow only to add namespace permissions policies for users or user groups. To edit permissions policies of users or user groups, click Edit Policy under Operation on the Permissions Management page.
• If you grant multiple permissions policies to a user or user group, all these policies will take effect at the same time. The permissions policies that you grant to a user group apply to all users in the user group.
• If you enable RBAC authentication, the union set of permissions policies of the same type will be used, and the intersection set of permissions policies of different types will be used. For example, if you add multiple IAM fine-grained policies to a user group, all these policies will take effect. Similarly, if you add multiple permissions policies to a user or user group on the CCI permissions management page, all these policies will take effect. A user with the CCI CommonOperations policy can create Deployments. However, if the user and the user group to which the user belongs are not granted the RBAC policy in the target namespace, the user will fail the authentication and cannot create the Deployment. That is, the intersection set of permissions policies of different types will be used.

Process Flow

A namespace is an abstract collection of resources and objects. You can create multiple namespaces in a cluster. Data is isolated between namespaces so namespaces can share the same cluster service without affecting each other. A namespace can act as a virtual cluster to meet diversified requirements.

This section describes how you can grant namespace permissions to the IAM user James and the user group Developers created in Creating a User and Granting CCI Permissions.

• Step 1: Grant Namespace Permissions to an IAM User or User Group
• Step 2: Log In and Verify Permissions

Step 1: Grant Namespace Permissions to an IAM User or User Group

In this step, you will grant user James who has the CCI CommonOperations policy permissions to view the target namespace.

1. Log in to the CCI console. In the navigation pane on the left, choose Permissions Management.
2. Click Add Permissions.

3. Select the namespace whose access you want to manage. In this example, select cci-namespace-demo-rbac.

4. Add the admin permissions policy for the user group Developers.
   • User/User Group: Select User group from the drop-down list and then select Developers from the user group list.
   • Permissions Policy: Select admin.

5. Click Add Policy for Namespaces. Add permissions on another namespace (cci-namespace-demo-rbac01) for user James.
   • Namespace: Select cci-namespace-demo-rbac01.
   • User/User Group: Select User from the drop-down list and then select James from the user list.
   • Permissions Policy: Select view.

6. Click OK. The namespace permissions granted to the user group and user are displayed in the permissions list.

   To sum up, the authorization result is as follows:

   • The user group Developers has admin permissions on the namespace cci-namespace-demo-rbac. The admin permissions policy also applies to the IAM user James in the user group Developers.
   • The IAM user James has view permissions on the namespace cci-namespace-demo-rbac01.

Step 2: Log In and Verify Permissions

Use the username James and identity credential to log in to the CCI console and verify that the IAM user James has the namespace permissions.
