Terraform Automation - Infrastructure as Code

Terraform for Network Automation with VyOS

Terraform, developed by HashiCorp, is a powerful Infrastructure as Code (IaC) tool that allows you to define, provision, and manage infrastructure in a simple, declarative way. Instead of configuring network devices manually, you describe the desired state in human-readable code, and Terraform takes care of creating, updating, or removing resources automatically.

Terraform enables you to

In modern network environments, agility and consistency are key.

Deploy physical, virtual, or cloud-based network devices at scale.

Automate configuration of routing protocols, VLANs, VPNs, and advanced services like EVPN or cloud gateway.

Integrate with multi-vendor APIs, SDN controllers, and orchestration platforms.

Version-control your infrastructure, enabling repeatable deployments and streamlined change management.

How Terraform Works

Terraform uses configuration files written in HashiCorp Configuration Language (HCL) to describe the desired infrastructure state.˙

Write

You define resources, which may be across multiple cloud providers and services. For example, you might create a configuration to deploy an application on virtual machines in a Virtual Private Cloud (VPC) network with security groups and a load balancer.

Plan

Terraform creates an execution plan describing the infrastructure it will create, update, or destroy based on the existing infrastructure and your configuration.

Apply

On approval, Terraform performs the proposed operations in the correct order, respecting any resource dependencies. For example, if you update the properties of a VPC and change the number of virtual machines in that VPC, Terraform will recreate the VPC before scaling the virtual machines.
