CLI tool for managing functions in AWS Lambda.

Lambkin

Lambkin is CLI tool for generating and managing simple functions in AWS Lambda.

Supporting Node.js and Python, Lambkin generates skeleton functions, provides lightweight help for managing dependencies, and does its best to hide the complexity of publishing and running functions in Lambda.

Quick Start

Prerequisites

• A valid ~/.aws/config file. eg.

  [default]
  region = us-west-2

• A valid ~/.aws/credentials file. eg.

  [default]
  aws_access_key_id = AKIAUAVOHGHOOWEEYIED
  aws_secret_access_key = 90kX2Y2bykTH9CpQFHCzN92tukYf26

• A working virtualenv command if you will be writing Lambda functions in Python.

Installing

• pip install lambkin

Examples

Create a new Python function from a basic template

lambkin create cool-func
$EDITOR cool-func/cool-func.py

…or a maybe you prefer Node.js

lambkin create cool-func --runtime=nodejs
$EDITOR cool-func/cool-func.js

Install packages and dependencies for your function

$EDITOR cool-func/Makefile
lambkin make cool-func

Bundle up your function (with libraries) and send it to Lambda

lambkin publish cool-func --description 'The best function ever.'

Increase the timeout for a long-running function

lambkin publish cool-func --description 'Slow' --timeout=300

Invoke the published function, right now!

lambkin run cool-func

Schedule the function to run at regular intervals

lambkin cron cool-func --rate='10 minutes'

Remove the function from Lambda, but keep it locally.

lambkin unpublish cool-func

Dependencies - pip and npm

Each function you create gets a Makefile at some-function/Makefile. This is the best place to install any dependencies. Examples for installing pip and npm packages are provided in the Makefile.

Nicer, more language-specific dependency management is planned for the future.
