Return values (Fn::GetAtt)

  • Functions: the functions.
  • FunctionNames: the names of the functions.
Property Type Description Constraint
FunctionNames List The names of the functions. None.
Functions List The functions. None.
FunctionName String The name of the function. None.
FunctionId String The ID of the function. The ID is globally unique.
Description String The description of the function. None.
Runtime String The runtime environment of the function. The following runtime environments are supported: Node.js 6.x, Node.js 8.x, Node.js 10.x, Node.js 12.x, Node.js 14.x, Python 2.7, Python 3, Java 8, Java 11, PHP 7.2, .NET Core 2.1, Go 1.x, Custom Runtime, and Custom Container.

For more information about the runtime environments that are supported by Function Compute, see Supported runtime environments.

Handler String The handler of the function. The format of the value varies based on the programming language that you use.

For more information, see Basics.

Timeout Number The timeout period for the execution of the function. Valid values: 1 to 86400.

Default value: 60.

Unit: seconds.

When this period expires, the execution of the function is terminated.

Initializer String The handler of the initializer function. The format of the value varies based on the programming language that you use.

For more information, see Basics.

InitializationTimeout Number The timeout period for the execution of the initializer function. Valid values: 1 to 300.

Default value: 3.

Unit: seconds.

When this period expires, the execution of the initializer function is terminated.

CodeSize Number The size of the function code package. Unit: bytes.
CodeChecksum String The CRC-64 value of the function code package. None.
MemorySize Number The memory size of the function. Unit: MB.

The memory size must be a multiple of 64 MB.

The memory size that is available for a function varies based on the instance type.

For more information, see Instance specifications.
GpuMemorySize Number The GPU virtual memory capacity for the function. None.
EnvironmentVariables Map The environment variables that are specified for the function. You can obtain the values of the environment variables from the function.

For more information, see Environment variables.

CreatedTime String The time when the function was created. None.
LastModifiedTime String The time when the function was last modified. None.
InstanceConcurrency Number The number of requests that can be concurrently processed by a single instance. None.
InstanceSoftConcurrency Number The number of requests that can be concurrently processed by multiple instances. None.
CustomContainerConfig Map The configurations of the custom container runtime. After you configure the custom container runtime, Function Compute can execute the function in a container created from a custom image. For more information, see CustomContainerConfig.
CaPort Number The port on which the HTTP server listens for the custom runtime or custom container runtime. None.
InstanceType String The instance type of the function. None.
Layers Map The information about layers. For more information, see Layer.
InstanceLifecycleConfig Map The configuration of the instance lifecycle function. For more information, see InstanceLifecycleConfig.
CustomDNS Map The custom Domain Name System (DNS) settings of the function. For more information, see CustomDNS.
CustomRuntimeConfig Map The configurations of the custom runtime function. For more information, see CustomRuntimeConfig.
