To create a Lambda function definition

The following create-function-definition example creates a Lambda function definition and an initial version by providing a list of Lambda functions (in this case, a list of just one function named TempMonitorFunction) and their configurations. Before you can create the function definition, you need the Lambda function ARN. To create the function and its alias, use Lambda's create-function and publish-version commands. Lambda's create-function command requires the ARN of the execution role, even though AWS IoT Greengrass doesn't use that role because permissions are specified in the Greengrass group role. You can use the IAM create-role command to create an empty role to get an ARN to use with Lambda's create-function or you can use an existing execution role.

aws greengrass create-function-definition --name MyGreengrassFunctions --initial-version "{\"Functions\": [{\"Id\": \"TempMonitorFunction\", \"FunctionArn\": \"arn:aws:lambda:us-west-2:123456789012:function:TempMonitor:GG_TempMonitor\", \"FunctionConfiguration\": {\"Executable\": \"temp_monitor.function_handler\", \"MemorySize\": 16000,\"Timeout\": 5}}]}"
