Create a policy

1. Log on to the Resource Access Management (RAM) console with an Alibaba Cloud account.

2. In the left-side navigation pane, choose Permissions > Policies.

3. On the Policies page, click Create Policy.

4. On the Create Policy page, click the JSON tab.

5. Enter the following policy document and click Next to edit policy information.

   {

           {
               "Action": [
                   "hdm:CreateCacheAnalysisTask",
                   "hdm:DescribeCacheAnalysisReportList",
                   "hdm:DescribeCacheAnalysisReport",
                   "hdm:CreateCacheAnalysisJob",
                   "hdm:DescribeCacheAnalysisJob",
                   "hdm:DescribeCacheAnalysisJobs",
                   "hdm:GetInstanceLatestBackup"
               ],
               "Resource": "acs:kvstore:*:*:instance/<ID of your ApsaraDB for Redis instance>",
               "Effect": "Allow"
           },
           {
               "Action": "ram:CreateServiceLinkedRole",

           }
       ],
       "Version": "1"
   }

6. Configure the Name and Description parameters.

   For example, you can set the Name parameter to das-redis-key-analysis-policy.

7. Check and optimize the document of the custom policy.

   • Basic optimization

     The system automatically optimizes the policy statement. The system performs the following operations during basic optimization:

     • Deletes unnecessary conditions.

     • Deletes unnecessary arrays.

   • Optional: Advanced optimization

     You can move the pointer over Optional advanced optimize and click Perform. The system performs the following operations during the advanced optimization:

     • Splits resources or conditions that are incompatible with actions.

     • Narrows down resources.

     • Deduplicates or merges policy statements.

8. Click OK.

Attach the policy to a RAM user

1. In the left-side navigation pane, choose Identities > Users.

2. On the Users page, find the required RAM user, and click Add Permissions in the Actions column.

3. In the Select Policy section of the Add Permissions panel, click Custom Policy and select the policy that you created, such as das-redis-key-analysis-policy.
