Requirements

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-cdk
    
  3. Run below command to install required dependancies:
    npm install
    
  4. From the command line, run:
    cdk deploy --all
    

Testing

  1. In the stack output, you can see ALBUrl and when access the url, you can get the response 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:
    cdk destroy --all
