create_function: Manage AWS Lambda Functions

In aws.lambda: AWS Lambda Client Package

Description

Create, update, and version AWS Lambda functions

Usage

create_function(
  name,
  func,
  handler,
  role,
  runtime = c("nodejs12.x", "nodejs10.x", "java11", "java8", "python3.8", "python3.7",
    "python3.6", "python2.7", "dotnetcore3.1", "dotnetcore2.1", "go1.x", "ruby2.7",
    "ruby2.5", "provided"),
  timeout = 3L,
  description,
  ...
)

update_function_code(name, func, ...)

update_function_config(
  name,
  description,
  handler,
  role,
  runtime = c("nodejs12.x", "nodejs10.x", "java11", "java8", "python3.8", "python3.7",
    "python3.6", "python2.7", "dotnetcore3.1", "dotnetcore2.1", "go1.x", "ruby2.7",
    "ruby2.5", "provided"),
  timeout = 3L,
  ...
)

update_function(
  name,
  func,
  description,
  handler,
  role,
  runtime = c("nodejs12.x", "nodejs10.x", "java11", "java8", "python3.8", "python3.7",
    "python3.6", "python2.7", "dotnetcore3.1", "dotnetcore2.1", "go1.x", "ruby2.7",
    "ruby2.5", "provided"),
  timeout = 3L,
  ...
)

publish_function_version(name, description, ...)

make_function_version(name, description, ...)

Arguments

name	A character string specifying the function name (either a full ARN or a max 64-character string). For functions other than create_function this can also be an object of class “aws_lambda_function”.
func	Either (1) a character string containing a url-style AWS S3 bucket and object key (e.g., "s3://bucketname/objectkey") where the object is the .zip file containing the AWS Lambda deployment package; (2) a file string pointing to a .zip containing the deployment package; or (3) a single file (e.g., a javascript file) that will be zipped and used as the deployment. The third option is merely a convenience for very simple deployment packages.
handler	A character string specifying the function within your code that Lambda calls to begin execution.
role	A character string containing an IAM role or an object of class “iam_role”. This is the role that is used when the function is invoked, so it must have permissions over any AWS resources needed by the function.
runtime	A character string specifying the runtime environment for the function.
timeout	An integer specifying the timeout for the function, in seconds.
description	Optionally, a max 256-character description of the function for your own use.
...	Additional arguments passed to lambdaHTTP.

Details

create_function creates a new function from a deployment package. update_function_code updates the code within a function. update_function_config updates the configuration settings of a function. publish_function_version records a function version (see list_function_versions; changes made between versioning are not recorded.

Value

A list of class “aws_lambda_function”.

Examples

## Not run: 
# 'hello world!' example code
hello <- system.file("templates", "helloworld.js", package = "aws.lambda")

# get IAM role for Lambda execution
library("aws.iam")
id <- get_caller_identity()[["Account"]]
# Note: This role may not work. We recommend copying the ARN of a
# Lambda-capable role from the console once until we're able to more
# smoothly integrate with aws.iam.
role <- paste0("arn:aws:iam::", id, ":role/lambda_basic_execution")

lambda_func <- create_function("helloworld",
  func = hello,
  handler = "helloworld.handler",
  role = role
)

# invoke function
invoke_function(lambda_func)

# delete function
delete_function(lambda_func)

## End(Not run)
