AWS lambda function infrastructure

This project provides the required AWS resources to deploy an AWS lambda function.

Prerequisites

• The Terraform CLI (1.0.1+) installed.
• An AWS Account

How to run

• Provide your AWS credentials

  export AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
  export AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
  

  Make sure the user has the enough permissions to create all the resources listed in resources.tf.
• Initialize the configuration.

  terraform init
  

• Apply the configuration. 🚀

  terraform apply
  

  If everything was good, you will get an output similar to this:

  Apply complete! Resources: 13 added, 0 changed, 0 destroyed.
  
  Outputs:
    base_url = "https://abcdef0j.execute-api.us-east-1.amazonaws.com/serverless_lambda_stage"
    function_name = "HelloWorld"
    lambda_bucket_name = "juanultimate-lightly-finally-brave-caribou"
  
  

Troubleshooting

If you get an error like this:

It means your user does not have the enough permission to create the required resources.
