/greengrass/definition/functions/FunctionDefinitionId/versions

POST

POST /greengrass/definition/functions/FunctionDefinitionId/versions

Operation ID: CreateFunctionDefinitionVersion

Creates a version of a Lambda function definition that has already been defined.

Produces: application/json

Body Parameters

CreateFunctionDefinitionVersionRequestBody

Information about the function definition version.

where used: body; required: true

{ "DefaultConfig": { "Execution": { "IsolationMode": "GreengrassContainer|NoContainer" } }, "Functions": [ { "Id": "string", "FunctionArn": "string", "FunctionConfiguration": { "Pinned": true, "Executable": "string", "ExecArgs": "string", "MemorySize": 0, "Timeout": 0, "EncodingType": "binary|json", "Environment": { "Variables": { "additionalProperty0": "string", "additionalProperty1": "string", "additionalProperty2": "string" }, "ResourceAccessPolicies": [ { "ResourceId": "string", "Permission": "ro|rw" } ], "AccessSysfs": true, "Execution": { "IsolationMode": "GreengrassContainer|NoContainer", "RunAs": { "Uid": 0, "Gid": 0 } } } } } ] }
FunctionDefinitionVersion

Information about a function definition version.

type: object

DefaultConfig

Default configuration that will apply to all Lambda functions in the group.

type: object

Execution

Configuration that defines the default containerization used for when running Lambda functions in the group. Individual Lambda functions can be override this setting.

type: object

IsolationMode

Specifies whether the Lambda function runs in a Greengrass container (default) or without containerization. Unless your scenario requires that you run without containerization, we recommend that you run in a Greengrass container. Omit this value to run the Lambda function with the default containerization for the group.

type: string

enum: ["GreengrassContainer", "NoContainer"]

Functions

A list of Lambda functions in this function definition version.

type: array

items: Function

Information about a Lambda function.

type: object

required: ["Id"]

Id

A descriptive or arbitrary ID for the function. This value must be unique within the function definition version. Max length is 128 characters with pattern [a‑zA‑Z0‑9:_‑]+.

type: string

FunctionArn

The ARN of the Lambda function.

type: string

FunctionConfiguration

The configuration of the Lambda function.

type: object

Pinned

True if the function is pinned. Pinned means the function is long-lived and starts when the core starts.

type: boolean

Executable

The name of the function executable.

type: string

ExecArgs

The execution arguments.

type: string

MemorySize

The memory size, in KB, which the function requires. This setting is not applicable and should be cleared when you run the Lambda function without containerization.

type: integer

Timeout

The allowed function execution time, after which Lambda should terminate the function. This timeout still applies to pinned Lambda functions for each request.

type: integer

EncodingType

The expected encoding type of the input payload for the function. The default is json.

type: string

enum: ["binary", "json"]

Environment

The environment configuration of the function.

type: object

Variables

Environment variables for the Lambda function's configuration.

type: object

additionalProperties: An object with properties of type string that represent the environment variables.

ResourceAccessPolicies

A list of the resources, with their permissions, to which the Lambda function will be granted access. A Lambda function can have at most 10 resources. ResourceAccessPolicies apply only when you run the Lambda function in a Greengrass container.

type: array

items: ResourceAccessPolicy

ResourceAccessPolicy

A policy used by the function to access a resource.

type: object

required: ["ResourceId"]

ResourceId

The ID of the resource. (This ID is assigned to the resource when you create the resource definiton.)

type: string

Permission

The type of permission a function has to access a resource.

type: string

enum: ["ro", "rw"]

AccessSysfs

If true, the Lambda function is allowed to access the host's /sys folder. Use this when the Lambda function needs to read device information from /sys. This setting applies only when you run the Lambda function in a Greengrass container.

type: boolean

Execution

Configuration information that specifies how the Lambda function runs.

type: object

IsolationMode

Specifies whether the Lambda function runs in a Greengrass container (default) or without containerization. Unless your scenario requires that you run without containerization, we recommend that you run in a Greengrass container. Omit this value to run the Lambda function with the default containerization for the group.

type: string

enum: ["GreengrassContainer", "NoContainer"]

RunAs

Specifies the user and/or group whose permissions are used when running the Lambda function. You can specify one or both values to override the default values (ggc_user/ggc_group). We recommend that you avoid running as root unless absolutely necessary to minimize the risk of unintended changes or malicious attacks. To run as root, you must set IsolationMode to NoContainer and you must update config.json in greengrass-root/config to set allowFunctionsToRunAsRoot to yes.

type: object

Uid

The User ID whose permissions are used to run a Lambda function.

type: integer

Gid

The Group ID whose permissions are used to run a Lambda function.

type: integer
