Creating the SCConnectLaunch role - AWS Service Management Connector

此页面尚未翻译为您的语言。请求翻译

The SCConnectLaunch role is an IAM role that places baseline AWS service permissions into the AWS Service Catalog launch constraints. Configuring this role enables segregation of duty through provisioning product resources for ServiceNow end users.

The SCConnectLaunch role baseline contains permissions to Amazon EC2 and Amazon S3 services. If your products contain more AWS services, you must either include those services in the SCConnectLaunch role or create new launch roles.

This section describes how to create the SCConnectLaunch role. This role places baseline AWS service permissions in the Service Catalog launch constraints. For more information, see Service Catalog Launch Constraints.

To create SCConnectLaunch role

Create this policy: AWSCloudFormationFullAccess policy. Choose create policy and add this code in the JSON editor:



{
   "Version":"2012-10-17",
   "Statement":[
      {
         "Effect":"Allow",
         "Action":[
            "cloudformation:DescribeStackResource",
            "cloudformation:DescribeStackResources",
            "cloudformation:GetTemplate",
            "cloudformation:List*",
            "cloudformation:DescribeStackEvents",
            "cloudformation:DescribeStacks",
            "cloudformation:CreateStack",
            "cloudformation:DeleteStack",
            "cloudformation:DescribeStackEvents",
            "cloudformation:DescribeStacks",
            "cloudformation:GetTemplateSummary",
            "cloudformation:SetStackPolicy",
            "cloudformation:ValidateTemplate",
            "cloudformation:UpdateStack",
            "cloudformation:CreateChangeSet",
            "cloudformation:DescribeChangeSet",
            "cloudformation:ExecuteChangeSet",
            "cloudformation:DeleteChangeSet",
            "s3:GetObject"
         ],
         "Resource":"*"
      }
   ]
}

Note

AWSCloudFormationFullAccess includes additional permissions for ChangeSets.

Create this policy: ServicecodeCatalogSSMActionsBaseline. Follow the instructions in Creating IAM policies, and add this code in the JSON editor:


{
   "Version":"2012-10-17",
   "Statement":[
      {
         "Sid":"Stmt1536341175150",
         "Action":[
            "servicecatalog:AssociateResource",
            "servicecatalog:DisassociateResource",
            "servicecatalog:ListServiceActionsForProvisioningArtifact",
            "servicecatalog:ExecuteprovisionedProductServiceAction",
            "ssm:DescribeDocument",
            "ssm:GetAutomationExecution",
            "ssm:StartAutomationExecution",
            "ssm:StopAutomationExecution",
            "ssm:StartChangeRequestExecution",
            "cloudformation:ListStackResources",
            "ec2:DescribeInstanceStatus",
            "ec2:StartInstances",
            "ec2:StopInstances"
         ],
         "Effect":"Allow",
         "Resource":"*"
      },
      {
         "Effect":"Allow",
         "Action":"iam:PassRole",
         "Resource":"*",
         "Condition":{
            "StringEquals":{
               "iam:PassedToService":"ssm.amazonaws.com"
            }
         }
      }
   ]
}

Create the SCConnectLaunch role. Then assign the trust relationship to Service Catalog.



                            {
          "Version": "2012-10-17",
          "Statement": [
            {
              "Sid": "",
              "Effect": "Allow",
              "Principal": {
                "Service": "servicecatalog.amazonaws.com"
              },
              "Action": "sts:AssumeRole"
            }
          ]
        }

Attach the relevant policies to the SCConnectLaunch role.

We recommend you customize and scope your launch policies to the specific AWS Services, which are in the associated CloudFormation template for the given Service Catalog product.

For example, to provision EC2 and S3 products, your role policies are as follows:
- AmazonEC2FullAccess AWS managed policy)
- AmazonS3FullAccess AWS managed policy)
- AWSCloudFormationFullAccess (custom managed policy)
- ServiceCatalogSSMActionsBaseline (custom managed policy)
