cfn-modules: EC2 PostgreSQL example project

This example project demonstrates how an EC2 instance can communicate with an RDS PostgreSQL database.

Prerequisites

  1. Install Node.js 8.x
  2. Create an S3 bucket where aws cloudformation package uploads the artifacts.
    1. Choose a unique bucket name, e.g. BucketName=cfn-modules-$Name-$Region
    2. Replace $Name with a unique name (e.g. your initials or company name)
    3. Replace $Region with your AWS default region (e.g. us-east-1)
    4. Create the bucket aws s3 mb s3://$BucketName

Usage

npm i
aws cloudformation package --template-file example.yml --s3-bucket $BucketName --output-template-file packaged.yml
aws cloudformation deploy --template-file packaged.yml --stack-name ec2-postgres-example --capabilities CAPABILITY_IAM
aws cloudformation describe-stacks --stack-name ec2-postgres-example --query "Stacks[0].Outputs[?OutputKey=='Url'].OutputValue" --output text

Open the URL in your web browser, login with the password insecure, and you will see a database management tool.

Don't forget to delete the stack once your are done with the demo:

aws cloudformation delete-stack --stack-name ec2-postgres-example
