Run Ansible Playbook From Terraform: Provision and Configure EC2 in AWS

This project demonstrates how to combine Terraform and Ansible to fully automate both infrastructure provisioning and post‑deployment configuration for an AWS bastion host. Specifically, it uses Terraform to define and deploy an EC2 instance as a bastion host, then immediately runs an Ansible playbook to install Docker and Docker Compose v2 on that instance, eliminating manual steps and reducing operational toil. The repository follows a modular directory structure (modules/ec2, modules/sshkey, ansible/) that separates infrastructure definitions from configuration logic. After setting VPC ID, subnet IDs, and SSH key variables, users run terraform plan and terraform apply, then Terraform’s provisioners handle SSH connectivity, bootstrap Ansible installation, and execute the playbook. This pattern streamlines Bastion host provisioning and automation by integrating Terraform with Ansible in a single workflow.
