Deploying an API with Terraform and APIGateway

What is this?

api_with_terraform demonstrates how to deploy lambda code as a service to API gateway.

By following the steps below you will cause example_handler in lambda_handlers/example/lambda to respond to a request at <aws_url>/example_path/example_stage/

Requirements

setting up AWS:

• AWS profile and account
• Credentials added to ~/.aws/credentials
• edit main.tf profile to point at name in ~/.aws/credentials

setting up Terraform:

For an easier install I like to move the Terraform executable to /usr/local/bin/ which is on my PATH. You will know it is installed correctly when you can run,

% terraform -v           127 ↵
Terraform v0.12.18

Use

package your lambda

Package your new lambda into a build.zip file,

• python package_lambda.py example

Set up Terraform in your lambda directory,

• cd lambda_handlers/example
• Run terraform init

See changes Terraform wants to run:

• terraform plan

Deploy your endpoint:

• terraform apply

Destroy your deployed resources:

• terraform destroy
