Setup AWS & CLI

• Login to AWS Management Console and Generate a new KeyPair. Save the downloaded key
• Configure AWS Command Line Interface (AWS CLI) with a new AWS Access Key and a secret generated on AWS
• Update the stack.yml if you're using this template for your application
• Use AWS CLI to run create-stack command that'll create all the resources defined in the stack.yml
• Update the docker-compose app.yml if you're using this for your application
• Using docker compose run database migration command, run service in background and run db-seed to populate test data

aws cloudformation create-stack --profile demo --stack-name blog-stage --template-body file://$PWD/stack.yml

# After the stack creation is successful, Get the IP address or DNS of the AppNode EC2 instance
ssh -i aws-key1.pem ubuntu@<IP ADDRESS OR DNS OF THE EC2 INSTANCE>

# Point your local to EC2 instance,
export DOCKER_HOST=tcp://35.160.122.95:2375
