Terraform is a powerful Infrastructure as Code (IaC) tool used for automating the provisioning, management, and scaling of infrastructure resources. It helps teams manage complex infrastructures efficiently by writing declarative configurations that define desired infrastructure states. Here’s what Terraform enables you to do:

What You Can Do with Terraform:

1. Provision Cloud Infrastructure:
   • Automate the creation of virtual machines, containers, databases, and network resources.
   • Work with major cloud providers like AWS, Azure, Google Cloud, Oracle Cloud, and more.
2. Standardize Multi-Cloud Environments:
   • Manage infrastructure across multiple cloud providers with consistent configurations.
   • Avoid vendor lock-in by maintaining portability of configurations between providers.
3. Deploy Hybrid Infrastructure:
   • Bridge the gap between on-premises systems and cloud environments.
   • Manage resources in data centers alongside cloud-based infrastructure.
4. Infrastructure Automation:
   • Replace manual provisioning processes with fully automated workflows.
   • Handle large-scale infrastructure changes with minimal human intervention.
5. Simplify Application Deployment:
   • Create and provision environments for deploying applications, including backend, frontend, and microservices.
6. Manage Network Resources:
   • Automate the setup of networking components like virtual private clouds (VPCs), subnets, gateways, and firewalls.
7. Resource Dependencies Management:
   • Automatically resolve dependencies between resources, ensuring that infrastructure is created and updated in the correct order.
8. Version-Control Infrastructure:
   • Use version control tools like Git to track changes to infrastructure configurations.
   • Roll back to previous states when needed, providing a safety net for experimentation.
9. Collaborate Across Teams:
   • Share modular, reusable configurations to promote consistent infrastructure practices.
   • Use remote state storage to enable team-based workflows and avoid conflicts.
10. Continuous Integration/Continuous Deployment (CI/CD):
    • Integrate Terraform into CI/CD pipelines to ensure infrastructure is updated alongside application deployments.
11. Implement Governance and Policy Enforcement:
    • Use tools like HashiCorp Sentinel with Terraform Enterprise to enforce policies and compliance.
    • Prevent unauthorized or unsafe changes to infrastructure.
12. Scale Infrastructure Dynamically:
    • Adjust infrastructure to handle varying workloads or traffic demands automatically.
    • Implement autoscaling strategies for cloud resources.
13. Disaster Recovery and Backup:
    • Simplify disaster recovery by re-creating infrastructure from stored configurations.
    • Store and retrieve Terraform states securely to maintain infrastructure history.
14. Cost Management:
    • Use Terraform to track and manage infrastructure costs by provisioning only necessary resources.
    • Clean up unused or outdated resources efficiently.
15. Migrate and Upgrade Infrastructure:
    • Assist in migrating infrastructure between regions, cloud providers, or environments.
    • Upgrade resources or adopt new services without manual reconfiguration.
16. Compliance and Auditing:
    • Ensure your infrastructure adheres to organizational policies.
    • Generate detailed plans and logs of all changes for auditing purposes.
17. Build Immutable Infrastructure:
    • Deploy immutable servers or resources, ensuring consistent performance and reducing configuration drift.
18. Test and Validate Configurations:
    • Use test environments to validate changes before applying them to production.
    • Leverage Terraform’s execution plans to preview the impact of changes.

Advantages of Using Terraform:

• Consistency: Create repeatable infrastructure across environments (e.g., dev, staging, production).
• Portability: Deploy infrastructure across diverse environments using the same configurations.
• Scalability: Easily adapt to growing infrastructure needs with automated scaling features.
• Flexibility: Works with a wide variety of providers and platforms, making it highly versatile.

Terraform simplifies infrastructure management and promotes operational efficiency, making it a cornerstone tool for modern DevOps and infrastructure engineering teams.

Step 1: Create an Instance

• Access the Dashboard: Log in to your Shape.Host account and navigate to your Dashboard.
• Click Create: Click on the “Create” button located in the top-right corner.
• Select Instances: From the dropdown menu, choose “Instances” to begin creating a new cloud server.

• Select Location: Choose a data center location for your instance closest to your target audience for optimal performance.

• Choose a Plan: Scroll through the available pricing plans. Select a plan based on your project requirements, such as Standard, CPU-Optimized, or Memory-Optimized.
• Choose an Image: Select Ubuntu 24.04 as the operating system for your instance.

• Authentication and Finalize: Choose your authentication method, either via SSH keys or password. Once done, click Create Instance to launch your server.

After your instance has been created, you can find the IP address by navigating back to the dashboard. This IP address will be needed to connect to your server via SSH.

To connect to your instance on Shape.Host, follow these steps:

Enter the Password: If prompted, enter your instance’s root password or use your SSH key if configured.

Get the Instance IP: After creating your instance, find the public IP address in the Shape.Host dashboard under Resources.

Open SSH Client: Use an SSH client like Terminal (Linux/macOS) or PuTTY (Windows).

SSH into the Instance: Run the following command in your terminal:

ssh root@<your-instance-ip>

Replace <your-instance-ip> with your actual instance IP address.

Step 2: Update and Upgrade System Packages

Start by updating your package list and upgrading existing packages to the latest versions:

apt update
apt upgrade -y

Step 3: Install Required Dependencies

Terraform requires certain dependencies, such as gnupg and software-properties-common, to manage package repositories securely. Install them using the following command:

apt install gnupg software-properties-common

Step 4: Add the HashiCorp GPG Key

Download and add the official HashiCorp GPG key to your system to verify the packages:

wget -O- https://apt.releases.hashicorp.com/gpg | gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg

Step 5: Add the HashiCorp Repository

Add the HashiCorp repository to your list of apt sources by executing the following command:

echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | tee /etc/apt/sources.list.d/hashicorp.list

Step 6: Update the Package List

After adding the HashiCorp repository, update the package list again to include packages from the new repository:

apt update

Step 7: Install Terraform

Now that the repository is configured, install Terraform using the following command:

apt install terraform

Step 8: Verify the Installation

Once Terraform is installed, verify the installation by checking the version:

terraform --version

You should see output showing the installed version of Terraform, confirming that the installation was successful.

By following this guide, you’ve successfully installed and configured Terraform on an Ubuntu Server 24.04. Terraform allows you to define, preview, and apply changes to your infrastructure efficiently.
