  AWS Lambda using Terraform., an Introductory Cookbook

The simplest HTTP API example is https://github.com/nsriram/lambda-the-terraform-way/tree/mas... is about 66 LOC of terraform. But wait, is uses lambda-role (12 LOC), lambda (27 LOC), api-gateway (47 LOC) & api-gateway-lambda-integration (40 LOC).

So 66+12+27+47+40=192 of terraform in a BUNCH of files.

Compare that to 47 LOC of verbose AWS SAM YAML:

  Djambda is an example project setting up Django application in AWS Lambda managed by Terraform.

  

I've played around with terraform and lambda in a web app context[1] and it works quiet nicely for creating per branch testing environments.

  Terraform module, which takes care of a lot of AWS Lambda/serverless tasks (build dependencies, packages, updates, deployments) in countless combinations 🇺🇦

  

kudos to OP for undertaking this but 10/10 recommend Anto Babenko's lambda module if you're not already using it: https://github.com/terraform-aws-modules/terraform-aws-lambd...

  Cloud cost estimates for Terraform in pull requests💰📉 Shift FinOps Left!

  

I'm wondering if people would find it useful to see the cost of using opensource projects that spin-up resources in their AWS accounts before they run `terraform apply`? Or maybe a repo shield/badge in the readme? (the idea came from https://github.com/infracost/infracost/issues/43)

I'm not sure how it could work for usage-based resources like Lambda/S3, maybe just assuming minimum usage for each resource is good enough to provide a rough monthly estimate? e.g. 1M Lambda requests, 1 GB storage and 1K S3 requests, then let users customize those numbers if they care to find out more?

  Terraform OpenFaaS provider

Alex, OpenFaaS founder here. The author has done a huge amount of work here, I am surprised that it's being given away for free, and not being monetized (it should be).

I often hear folks complain that Kubernetes is complex, and hard to understand. We've done a lot of work to make the experience of deploying functions simple on K8s, with very little to manage. But it still costs you a K8s cluster.

We created a new of openfaas called "faasd" which can run very well somewhere like DO or Hetzner for 3 EUR / mo. It doesn't include clustering, but is likely to be suitable for a lot of folks, who don't want to get deep into IAM territory.

The REST API for OpenFaaS has a terraform provider that works with either version - https://github.com/ewilde/terraform-provider-openfaas

And there's a guide on setting up faasd with TLS on DigitalOcean, it took about 30 seconds to launch, and makes building functions much simpler than Lambda. "faas-cli up"

https://www.openfaas.com/blog/faasd-tls-terraform/

If I were going to use Lambda, the author's examples are probably what I would turn to, but there are other ways and it needn't be this complex.
