AWS Lambda using Terraform., an Introductory Cookbook

AWS Lambda the Terraform Way

The objective of this tutorial is to understand AWS Lambda in-depth, beyond executing functions, using Terraform. This tutorial walks through setting up Terraform, dependencies for AWS Lambda, getting your first Lambda function running, many of its important features & finally integrating with other AWS services.

Terraform

Terraform will be the primary medium of demonstrating all these examples. Terraform is an infrastructure as code software that helps in managing resources in cloud, by various providers like AWS, GCP, Azure etc., Terraform enables creation of infrastructure by writing code in a declarative form.

Target Audience

Target audience for this tutorial series are developers with basic knowledge of Terraform. A little background on understanding of serverless technologies, infrastructure as code will help.

Note : The tutorial will not discuss examples using the AWS website UI (or) with AWS SDK.

lambda-the-terraform-way's Issues

serverless.tf and more

Hi Sriram,

Thanks for putting it all together in large comprehensive documents. Doing serverless with Terraform is way too hard and should be easier if you need to do more than just hello-world, and it is a really great idea to break the journey down into pieces.

The thing which I wanted to propose (in a rather inappropriate way, I know!), was to mention alternative projects Terraform users may benefit from:

• Doing serverless with Terraform - http://serverless.tf/ ( source: https://github.com/antonbabenko/serverless.tf )
• Playground code: https://github.com/antonbabenko/serverless.tf-playground
• Terraform AWS Lambda module (very much complete) - https://github.com/terraform-aws-modules/terraform-aws-lambda

PS: I apologize for the initial marketing spam (initial text of this issue). Make this a marketing spam was certainly not my goal.

Typo

Here, the lambda-tf-bucket corresponds to a local name that can be used for referencing in terraform code. The actual bucket will be created with name lambda-tf-tutorial-bucket.

I think that should be “the aws_s3_bucket”.

Document keybase steps

Hi, thanks for the great tutorial.

I got a bit stuck on the initial setup, having never heard of keybase before (and still not really understanding what it is). I eventually got it working through the following steps:

• Install keybase (duh)
• Create an account
• Open up the People tab, go to Edit Profile
• Click "Add pgp key"
• Input fake email
• Generate the key
• Close keybase (but DO NOT log out)

Now when running terraform apply, the keybase_id to give is your keybase username. As I understand it, terraform will query your local keybase install and get a pgp key from it.

It might be useful to add these steps to the tutorial - either way, hopefully this issue will help others.
