# Terraforming AWS: learning material and demos

Start from following the main tutorial: https://developer.hashicorp.com/terraform/tutorials/aws-get-started and other resources to learn terraform and play with some simple architectures in AWS.

## How to

Open each subfolders then run `terraform init` to fetch modules dependencies, then `terraform plan` to see the planning configuration, or to deploy use `terraform apply` to create resources on AWS. 

You can incur in some charges for resources usage on AWS (most resources used in the samples are in the free tier if you have a new aws account like for ec2 micro), so always remember to `terraform destroy` to remove the resources on AWS after you see the expected results of your tests.

## Common workflow for each exercise

- `terraform init`: fetch dependencies

- `terraform fmt`: format your template files

- `terraform validate`: validate the files

- `terraform plan`: check the planning on AWS that terraform will apply

- `terraform apply`: run deployment on AWS

- `terraform show`: show terraform current state

- `terraform destroy`: run deployment on AWS

## Table of Contents

- [Exercise 0: setup terraform](./0_setup/README.md): install the terraform CLI and check prerequisites

- [Exercise 1: docker test on local machine](./1_docker_local/README.md): test terraform running a docker container locally

- [Exercise 2: terraform basics](./2_aws_instance/README.md): following the main tutorial we will try to deploy an ec2 instance, try basics commands and workflow using terraform, try terraform cloud

- [Exercise 3: terraform variables](./3_variables/README.md): terraform different types of variables 

- TODO

- [Architecture examples](./aws_architecture_examples/README.md): Different architectures on AWS using terraform, common patterns.

## TODO: learning terraform basics

- [X] learn the basic CLI commands and workflow

- [X] most common variables types: string, numbers, bool, list, map

- [ ] local modules: to structure and encapsulate the configuration of the infra in a maintainable way

- [ ] test: we could work in terraform using tests and mocks!

## TODO: AWS architectures Ideas

Here are some ideas to try on AWS with terraform: 

- [X] EC2 basics: create an ec2 instance, simple settings

- [ ] EC2: autoscaling, spot, other specific settings?

- [X] s3 bucket

- [ ] s3 bucket for website hosting and CORS

- [ ] API Gateway > lambda (and optionally cognito for user auth?)

- [ ] lambda layers?

- [ ] s3 > SQS > lambda

- [ ] Custom VPC, NAT, subnets, ...

- [ ] Beanstalk for web: ELB, ec2, autoscaling, RDS optionally

- [ ] ECS: ec2, config, ECR for private docker repo

- [ ] CodeBuild, CodePipeline, ...
