This Terraform project provisions a free-tier Oracle Cloud Infrastructure (OCI) virtual machine (VM) with an attached block volume. It is designed to help users quickly deploy and manage a free-tier VM instance with persistent storage.

• Provisions a free-tier VM instance in OCI.
• Attaches a block volume for persistent storage.
• Configurable through terraform.tfvars.
• Uses cloud_init.yaml for instance initialization.

1. Install Terraform.
2. Set up an OCI account and generate API keys.
3. Configure your OCI CLI with the required credentials.

1. Clone the Repository

   git clone <repository-url>
   cd oci_free_vm_with_volume

2. Configure Variables Update the terraform.tfvars file with your OCI credentials and desired configuration:

   tenancy_ocid = "<your-tenancy-ocid>"
   user_ocid    = "<your-user-ocid>"
   region       = "<your-region>"
   compartment_ocid = "<your-compartment-ocid>"
   ssh_public_key = "<path-to-your-ssh-public-key>"

3. Initialize Terraform Run the following command to download the required providers:

   terraform init

4. Plan the Deployment Preview the changes that Terraform will make:

   terraform plan

5. Apply the Configuration Deploy the resources to OCI:

   terraform apply

   Confirm the prompt with yes.

6. Access the VM Use the public IP address of the VM to SSH into it:

   ssh -i <path-to-private-key> opc@<vm-public-ip>

To destroy the resources created by this project, run:

terraform destroy

Confirm the prompt with yes.

• main.tf: Defines the OCI resources to be provisioned.
• variables.tf: Declares input variables for the project.
• terraform.tfvars: Contains user-specific variable values.
• cloud_init.yaml: Specifies initialization scripts for the VM.
• .terraform.lock.hcl: Tracks provider versions.

• Ensure that your OCI account has sufficient free-tier resources available.
• Modify cloud_init.yaml to customize the VM initialization process.
