Simple AWS Lambda Maker

This is a super simple tool for creating/modifying multiple lambda functions.

It was built for the purpose of deploying our Alexa skills across multiple regions in the same account.

Installation

Just use pip:

$ pip install simple-aws-lambda-maker

Then create a salm.yml with something like:

---

function_defaults:
  filepath: "{config_root}/lambda_function.py"
  runtime: "python2.7"
  role: "arn:aws:iam::1234567890:role/lambda_basic_execution"
  timeout: 8
  handler: "lambda_function.lambda_handler"

functions:
  prod:
    - name: test
      region: us-east-1
      description: "Test function"
      env:
        ONE: "1"
        TWO: "2"
      tags:
        three: "four"

    - name: test2
      region: us-east-1
      description: "Test function 2"
      env:
        ONE: "3"
        TWO: "4"
      tags:
        three: "four"

  staging:
    - name: test3
      region: us-east-1
      description: "Test function 2"
      env:
        ONE: "5"
        TWO: "6"
      tags:
        three: "four"

Here we are creating three functions, called test, test2 and test3.

They are all put into us-east-1 and have different values for the ONE and TWO environment variables.

All of them also have the options in the function_defaults block, which includes a reference to a file relative to this file called ./lambda_function.py

For example:

import os
def lambda_handler(event, context):
    return "{0} - {1}".format(os.environ["ONE"], os.environ["TWO"])

We can then determine if anything will be created or changed by going into that directory and saying:

$ salm deploy staging --dry-run

And then to actually apply those changes:

$ salm deploy staging

And to do the prod group, do a salm deploy prod
