ALIYUN::FC::Service is used to create a service. All functions of a service share the same settings, such as service authorization and log configurations. A service can have multiple functions, all of which share service resources, such as Logstores and RAM roles.

A service helps you clearly organize your business logic and serves as the basic unit for O&M management. A service can represent an application. The functions that are used in the same application belong to a single service. Services are independent of each other and cannot share resources with each other.

  }
}

Properties

Property Type Required Editable Description Constraint
Description String No Yes The description of the service. None
VpcConfig Map No Yes The configurations of the virtual private cloud (VPC). The configurations allow functions to access the specified VPC. For more information, see VpcConfig properties.

If you want to delete the VPC configurations when you update a stack, set this property to the following value: 

{
  "VpcId": "",
  "VSwitchIds": [],
  "SecurityGroupId": ""
}
ServiceName String Yes No The name of the service. The name must be 1 to 128 characters in length, and can contain letters, digits, underscores (_), and hyphens (-). The name must start with a letter or an underscore (_).
Role String No Yes The Alibaba Cloud Resource Name (ARN) of the RAM role that is used to grant the required permissions to Function Compute. You can use the RAM role in the following scenarios:
  • You want to send the function execution logs to your Logstore.
  • You want to generate a token for a function to access other Alibaba Cloud resources when the function is invoked.
NasConfig Map No Yes The configurations of Apsara File Storage NAS (NAS). The configurations allow functions to access the specified NAS resources. For more information, see NasConfig properties.

If you want to delete the NAS configurations when you update a stack, set this property to the following value: 

{
  "MountPoints": [],
  "UserId": -1,
  "GroupId": -1
}
LogConfig Map No Yes The log configurations. The function execution logs are written to a Logstore that you specify in the configurations. For more information, see LogConfig properties.
TracingConfig Map No Yes The configuration of Tracing Analysis. After Function Compute is integrated with Tracing Analysis, you can record the duration of a request in Function Compute, view the cold start time of a function, and record the execution duration of a function.

For more information, see TracingConfig properties.

InternetAccess Boolean No Yes Specifies whether functions can access the Internet. Valid values:
  • true
  • false
DeletionForce Boolean No Yes Specifies whether to forcefully delete the service. This property takes effect when you specify the VpcConfig property. Default value: false. Valid values:
  • true: The service is deleted before all elastic network interfaces (ENIs) that Function Compute creates for the service are deleted.
    Note If you specify the vSwitch or security group in the ALIYUN::FC::Service resource type, you can set the DeletionForce property to true to directly delete the service.
  • false: The service is deleted until all ENIs that Function Compute creates for the service are deleted.

If the service is created based on a vSwitch or security group created in the current stack, you do not need to specify the DeletionForce property when you delete the service. After you delete the service, you cannot invoke the functions of the service within 1 hour. This way, the ENIs and the stack can be deleted as expected.

Tags List No Yes The tags of the service. You can specify up to 20 tags.

For more information, see Tags properties.

VpcBindings List No Yes The list of VPC IDs that you bind to Function Compute. By default, you can use public endpoints and private endpoints to invoke functions after the functions are created. If you want to invoke a function over the specified VPC, you must bind the VPC to Function Compute.

You can specify up to 20 VPC IDs.
