• Ansible
• Terraform

• Run the following command to generate elliptic curve ssh key pair

ssh-keygen -t ed25519 -f ~/.ssh/ansbile_ed25519 -C ansible

• Optionally, you can generate RSA key pair

ssh-keygen -t rsa -f ~/.ssh/ansbile -C ansible -b 2048

• Go to compute engine section
• Click Metadata
• Select SSH KEYS tab and click ADD SSH KEY
• Upload public ansbile_ed25519.pub key
  • cat ~/.ssh/ansbile_ed25519.pub

• Create roles/nginx/tasks/main.yaml task
• Create nginx.yaml playbook
• Create Ansible config ansible.cfg to skip host key verification

• Create terraform file 1-example.tf
• Open default firewall rules
• Verify that you have Terraform and Ansible installed

command -v terraform command -v ansible-playbook

• Run terraform init to download provider and plugins
• Run terraform apply to create Nginx instance in GCP

• Destroy previous example terraform destroy
• Copy 1-example.tf -> 2-example.tf
• Rename 1-example.tf -> 1-example.tf.bac
• Add local variable

 web_servers = { nginx-000-staging = { machine_type = "e2-micro" zone = "us-central1-a" } nginx-001-staging = { machine_type = "e2-micro" zone = "us-central1-b" } } 

 for_each = local.web_servers name = each.key machine_type = each.value.machine_type zone = each.value.zone 

host = self.network_interface.0.access_config.0.nat_ip 

command = "ansible-playbook -i ${self.network_interface.0.access_config.0.nat_ip}, --private-key ${local.private_key_path} nginx.yaml" 

output "nginx_ips" { value = { for k, v in google_compute_instance.nginx : k => "http://${v.network_interface.0.access_config.0.nat_ip}" } } 

• Run terraform apply

• terraform destroy
• rm ~/.ssh/ansbile*
• Delete SSH public key from GCP project
