How to grant a RAM role the required permissions so that a Scheduled SQL job can assume the role to process data in the same Alibaba Cloud account - Simple Log Service

When Scheduled SQL jobs run, the jobs execute SQL statements to analyze data in source Logstores, and then save the analysis results to destination Logstores. You can assign a Resource Access Management (RAM) role to a Scheduled SQL job to complete the preceding operations. If the source and destination Logstores belong to the same Alibaba Cloud account, perform the steps that are described in this topic to grant permissions to the RAM role. You can specify Logstores or Metricstores when you configure Scheduled SQL jobs. This topic describes how to grant a RAM role the permissions to access Logstores in the same Alibaba Cloud account.

Prerequisites

A RAM role is created. For more information, see Create a RAM role.

Important

When you create the RAM role, select Alibaba Cloud Service as the trusted entity.

In the trust policy of the RAM role, the "Service" field must include "log.aliyuncs.com", as illustrated below.

{
  "Statement": [
    {
      "Action": "sts:AssumeRole",
      "Effect": "Allow",
      "Principal": {
        "Service": [
          "log.aliyuncs.com"
        ]
      }
    }
  ],
  "Version": "1"
}

Grant the RAM role the permissions to analyze log data in a source Logstore

After you grant the RAM role the permissions to analyze data in a source Logstore, a Scheduled SQL job can assume the RAM role to perform SQL analysis on data in the source Logstore.

Log on to the Resource Access Management (RAM) console.

Create a policy that contains the permissions to analyze the log data of a source Logstore.

In the left-side navigation pane, choose Permissions > Policies.
Click Create Policy.

On the Create Policy page, click the JSON tab. Replace the existing script in the code editor with one of the following policy documents. Exact match or fuzzy match are supported for authorization.

Exact match for authorization

In this example, the name of the source project is log-project-prod. The name of the source Logstore is website_log. You must replace the names with the actual names of your projects and Logstores.

Important

When you create a policy, you can specify either a Logstore or Metricstore after the logstore keyword. If you want to manage Metricstores, you can also refer to the following policy document to create a policy.

{
    "Version":"1",
    "Statement":[
        {
            "Action":[
                "log:PostProjectQuery"
            ],
            "Resource":[
                "acs:log:*:*:project/log-project-prod/logstore/website_log",
                "acs:log:*:*:project/log-project-prod/logstore/website_log/*"
            ],
            "Effect":"Allow"
        },
        {
            "Action":[
                "log:GetProjectQuery",
                "log:PutProjectQuery",
                "log:DeleteProjectQuery"
            ],
            "Resource":[
                "acs:log:*:*:project/log-project-prod"
            ],
            "Effect":"Allow"
        }
    ]
}

Fuzzy match for authorization

In this example, the names of the source projects are log-project-dev-a, log-project-dev-b, and log-project-dev-c. The names of the source Logstores are website_a_log, website_b_log, and website_c_log. You must replace the names with the actual names of your projects and Logstores.

{
    "Version":"1",
    "Statement":[
        {
            "Action":[
                "log:PostProjectQuery"
            ],
            "Resource":[
                "acs:log:*:*:project/log-project-dev-*/logstore/website_*_log",
                "acs:log:*:*:project/log-project-dev-*/logstore/website_*_log/*"
            ],
            "Effect":"Allow"
        },
        {
            "Action":[
                "log:GetProjectQuery",
                "log:PutProjectQuery",
                "log:DeleteProjectQuery"
            ],
            "Resource":[
                "acs:log:*:*:project/log-project-dev-*"
            ],
            "Effect":"Allow"
        }
    ]
}
