Automating Vultr Cloud Infrastructure with Terraform — SitePoint

Introduction

Terraform is an open-source Infrastructure as Code (IaC) device. It permits customers to outline, provision, and handle cloud infrastructure utilizing declarative configuration information. With Terraform, you may automate the creation and administration of sources equivalent to servers, databases, networking, and storage throughout cloud suppliers.

One in every of Terraform’s strengths is its capability to keep up the state of infrastructure, guaranteeing consistency and enabling straightforward updates or scaling. By utilizing version-controlled configurations, groups can collaborate extra successfully, and infrastructure modifications develop into repeatable and predictable.

This text explains find out how to provision Vultr Cloud Infrastructure utilizing Terraform. You’re to provision a number of sources equivalent to cloud situations, Kubernetes Clusters, and databases utilizing your Vultr Account API key.

Provision Vultr Sources With Terraform

Setup Terraform

1. Obtain Terraform relying in your OS sort.
2. Create a Terraform listing to retailer the useful resource information.
3. Swap to the listing.
4. Create a brand new file supplier.tf to retailer the Vultr supplier info.
5. Copy and paste the beneath content material.

   Save and shut the file.

6. Create a brand new file named terraform.tfvars to outline your Vultr API key.
7. Copy and paste the beneath directive within the file.
8. Initialize Terraform to put in the Vultr Terraform supplier.

   Output ought to show a message informing Terraform has been efficiently initialized.

Provision a Vultr Cloud Compute Occasion

1. Create a brand new file named vultr_instance.tf.
2. Copy and paste the beneath content material.
   • vultr_instance: Units the Vultr useful resource sort you propose to deploy.
   • label: Specifies the occasion label.
   • plan: Units your required occasion specification. vc2-1c-1gb plan matches a Vultr occasion with sort vc2, 1 vCPU core, and 1 GB RAM.
   • area: Specifies your required Vultr area to deploy the occasion. sgp deploys the occasion to the Singapore Vultr location.
   • os_id: Units the occasion Working System (OS) by ID. The worth 2284 represents Ubuntu 24.04.
3. Preview the modifications you might be about to use.
4. Create the Vultr occasion.

   When prompted, enter sure to substantiate that you just wish to apply the modifications. When profitable you need to be capable to see the useful resource created within the Vultr Buyer Portal.

Provision A number of Sources at As soon as

1. Create a brand new file named fundamental.tf.
2. Copy and paste the beneath content material.

   Save and shut the file.

   This Terraform configuration defines two sources on Vultr:

   1. Vultr Cloud Compute Occasion: The vultr_instance useful resource provisions a digital machine (VM) labeled as “sample-server2”. The occasion is configured to:
      • Use the vc2-1c-1gb plan, which offers 1 CPU and 1GB of RAM.
      • Be deployed within the Bangalore (blr) area.
      • Run Ubuntu 24.04 (specified by os_id = “2284”).
      • Allow IPv6 for the occasion.
   2. Vultr Kubernetes Cluster: The vultr_kubernetes useful resource units up a Kubernetes cluster labeled “my-cluster2” within the Bangalore (blr) area, with Kubernetes model v1.31.0+1. The cluster has:
      • A node pool of three nodes, every utilizing the vc2-2c-4gb plan (2 CPUs and 4GB of RAM per node).
      • Auto-scaling enabled, with a minimal of 1 node and a most of 4 nodes within the pool.

   Collectively, this configuration permits for provisioning a single cloud compute occasion alongside a scalable Kubernetes cluster, all managed by way of Terraform.

3. Preview the modifications you might be about to use.
4. Create the Vultr sources.

   When prompted, enter sure to substantiate that you just wish to apply the modifications. When profitable you need to be capable to see the useful resource created within the Vultr Buyer Portal.

   You can even provision different Vultr Sources equivalent to Object and Block Storage, and Vultr Managed Databases.
