This is a toy project set up for the purpose of learning Terraform and becoming more comfortable with some AWS services.

The initial idea was to: - have the ability to trigger an api gateway endpoint to populate a dynamo database with via a lambda - be able to retrieve stored data through api gateway endpoint

I am using aws-vault as a way interact with AWS

• create tfvars (see dev.ftvars.example) file and supply all values
• first run will require terraform init to download dependancies
• (optional) aws-vault exec {profile name} -- terraform plan -var-file="{choose name}.tfvars" to create execution plan and review expected changes
• aws-vault exec {profile name} -- terraform apply -var-file="{choose name}.tfvars" to execute the plan and create resources in AWS
• aws-vault exec beattie19 -- terraform destroy -var-file="{choose name}.tfvars" when finished to remove resources from AWS

Once the terraform apply is successful there should be some outputs on the cli

• /populate - Path to populate database with Pokemon data
• /all-pokemon - Path retrieve all Pokemon data

• Create a better usage section
• Add screenshots from Miro

• Come up with a new solution that won't take down the database on destroy
• Pass SQS queue into the lambda event so it's not hard coded
• Improve lambda for creating messages (may currently timeout) - may want a lambda that triggers a lambda.
• Some duplication in API Gateway, consider creating a module.

• It would be good to be able to test locally
  • could localstack work for my usecase?
• Should I consider SAM for the lambda/api gateway instead?
• Can docker fit into this in anyway
• Add testing
  • terratest?
• Consider CI/CD? - could have build steps for testing

• Hit the /populate endpoint
• Trigger lambda to create SQS messages for each pokemon
• Each message is picked up by a lambda which reached out to the pokemon api and populates dynamo

You can set the concurrency for a lambda to zero (or click Throttle) to ensure the lambda is not invoked - This could allow the message to remain on the queue for inspection.
