1. Set-up:

To connect to your Amazon account before compiling the project you need to execute following steps with your AWS credentials:

• create file config.sh and save it to the /scripts folder with following content:

  #!/bin/bash
  
  DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )"
  
  export PATH=<path-to-aws>
  export AWS_DEFAULT_REGION=<region>
  export AWS_ACCOUNT_ID=<your-account-id>
  export AWS_ACCESS_KEY_ID=<your-access-key-id>
  export AWS_SECRET_ACCESS_KEY=<your-secret-access-key>
  export AWS_EC2_SSH_KEYPAIR_PATH=<your-path-to-key>
  export AWS_SECURITY_GROUP=<security-group-name>
  export AWS_KEYPAIR_NAME=<your-keypair-name>
  
  

• create file instance.properties and save it to the /service/src/main/java/pt/ulisboa/tecnico/cnv/webservice folder with following content:

  instanceType=<instance-type e.g. t2.micro>
  keyName=<name-of-your-key>
  securityGroup=<security-group-name>
  
  

• create file profile.credentials and save it to the /service/src/main/java/pt/ulisboa/tecnico/cnv/webservice folder with following content:

  [default]
  aws_access_key_id = <your-access-key-id>
  aws_secret_access_key = <your-secret-access-key>
  

2. Compilation:

• to launch the project on AWS execute following command in the /scripts directory:

  source create-environment.sh
  
  

• to terminate the project with all of its AWS services execute following command in the /scripts directory:

  source delete-environment.sh
  
  

3. Request:

For sending the requests you can execute any of the HTTP requests for some of the 3 endpoints with specified parameters, e.g.:

curl <service.dns>:8000/simulate\?generations=5\&world=1\&scenario=1

The service.dns is DNS of the EC2 instance running LoadBalancer and is printed to the console after the create-environment script is finished.

• Health-check:

  curl <service.dns>:8000/test
