Getting Started

1. Install Terraform CLI and required cloud CLI tools.
2. Change into the lab directory you want to run.
3. Initialize Terraform:

cd lab-04
terraform init

4. Review the plan:

terraform plan

5. Apply the configuration:

terraform apply

6. After deployment, locate the output values or the provisioned public IP address.

Example: WordPress Lab

The WordPress lab uses Terraform provisioning together with Ansible roles to install and configure WordPress on a cloud VM.

cd lab-04
terraform init
terraform plan
terraform apply

Best Practices

• Keep Terraform state secure and out of version control.
• Use .gitignore to exclude .tfstate, .terraform, and sensitive files.
• Use data sources for the latest cloud image IDs.
• Limit SSH access to trusted IP addresses.
• Tag resources and use descriptive variable names.

Notes

This repository is designed for learning and demonstration purposes. Customize variables and provider settings before running in production.
