Important: this application uses various AWS services and there are costs associated with these services after the Free Tier usage - please see the AWS Pricing page for details. You are responsible for any AWS costs incurred. No warranty is implied in this example.

Requirements

• Create an AWS account if you do not already have one and log in. The IAM user that you use must have sufficient permissions to make necessary AWS service calls and manage AWS resources.
• AWS CLI installed and configured
• Git Installed
• Terraform Installed

Deployment Instructions

1. Create a new directory, navigate to that directory in a terminal and clone the GitHub repository:

   git clone https://github.com/aws-samples/serverless-patterns
   

2. Change directory to the pattern directory:

   cd alb-lambda-terraform
   

3. From the command line, run:

   terraform init
   

4. From the command line, run:

   terraform plan
   

5. From the command line, run:

   terraform apply --auto-approve
   

Testing

1. In the stack output, you can see alb_url. When you access the url, you should see the response "Hello World" from Lambda.

** Please note: Application Load Balancer's default settings for health check are 5 consecutive health check successes with 35 seconds interval. So, it will take couple of minutes for the target to be healthy.

Cleanup

1. To delete the stack, run:

   terraform destroy --auto-approve
