This topic describes the scenarios of the service-linked role AliyunServiceRoleForGaFlowlog and how to create and delete the service-linked role.
Overview
AliyunServiceRoleForGaFlowlog is a service-linked role of Global Accelerator (GA). After you create AliyunServiceRoleForGaFlowlog, GA can access your Log Service and deliver logs to Log Service.
Note A service-linked role is a Resource Access Management (RAM) role that is associated with an Alibaba Cloud service. In some scenarios, to use a feature of a cloud service, you must obtain the permissions to access other cloud services. Service-linked roles simplify the authorization process and avoid risks caused by user errors. For more information, see Service-linked roles.
Permissions required to create AliyunServiceRoleForGaFlowlog
You can use an Alibaba Cloud account to create AliyunServiceRoleForGaFlowlog. If you want to create AliyunServiceRoleForGaFlowlog as a RAM user, the RAM user must first obtain the following permissions:
{
"Action": "ram:CreateServiceLinkedRole",
"Resource": "*",
"Effect": "Allow",
"Condition": {
"StringEquals": {
"ram:ServiceName": "flowlog.ga.aliyuncs.com"
}
}
}
You can grant the RAM user the required permissions in one of the following ways:
- Attach the administrator permission policy AliyunGlobalAccelerationFullAccess to the RAM user. For more information, see Grant permissions to a RAM role. Note The permission to create a service-linked role is included in AliyunGlobalAccelerationFullAccess. Therefore, you can create a service-linked role as a RAM user after you attach AliyunGlobalAccelerationFullAccess to the RAM user.
- Create a custom permission policy and attach it to the RAM user. The following code block shows the content of the custom permission policy:
{ "Action": "ram:CreateServiceLinkedRole", "Resource": "*", "Effect": "Allow", "Condition": { "StringEquals": { "ram:ServiceName": "flowlog.ga.aliyuncs.com" } } }
For more information, see Create custom policies and Grant permissions to a RAM role.
Create AliyunServiceRoleForGaFlowlog
After you enable the log delivery feature of flow logs for GA, the system automatically creates the service-linked role AliyunServiceRoleForGaFlowlog, and attaches a permission policy named AliyunServiceRolePolicyForGaFlowlog to it. The permission policy allows GA to access flow logs. The following code block shows the content of the permission policy:
{
"Version": "1",
"Statement": [
{
"Action": [
"log:PostLogStoreLogs"
],
"Resource": "*",
"Effect": "Allow"
},
{
"Action": "ram:DeleteServiceLinkedRole",
"Resource": "*",
"Effect": "Allow",
"Condition": {
"StringEquals": {
"ram:ServiceName": "flowlog.ga.aliyuncs.com"
}
}
}
]
}
Delete AliyunServiceRoleForGaFlowlog
The system cannot automatically delete the service-linked role AliyunServiceRoleForGaFlowlog of GA. To manually delete AliyunServiceRoleForGaFlowlog, delete all GA instances first. For more information, see Delete a service-linked role.
