ec2_keypair_public_key="<Public key of your SSH key pair>"

# Replace <Public key of your SSH key pair> with the public key of your own SSH key pair.
# It will be used provision the EC2 instance and allow Ansible to authenticate

3. (optional) Update the default value ~/.ssh/id_rsa to your private key file path in ansible_ssh_private_key_file from ../ansible/inventory.template
4. Initialize terraform dependencies by

terraform init

5. Get the list of resources being created by

terraform plan

2. Install nginx package and start the service on newly created EC2 instance by

ansible-playbook -i inventory install_nginx.yaml
