🚀 Automate MikroTik Router Configuration with Terraform | Infrastructure as Code Tutorial

Tired of logging into WinBox or SSH every time you need to change a firewall rule, add a DHCP lease, or reconfigure an interface? In this complete step-by-step tutorial, you'll learn how to use Terraform to fully automate your MikroTik RouterOS configuration — the same way DevOps engineers manage cloud infrastructure, but applied directly to your network hardware.

Whether you're managing a homelab, a small business network, or a multi-site enterprise deployment, this video will show you how to bring the power of Infrastructure as Code (IaC) to your MikroTik routers — making your configs repeatable, version-controlled, and disaster-recovery ready.

💡 Why Terraform + MikroTik?
MikroTik routers are incredibly powerful — but managing them at scale manually is slow, error-prone, and impossible to audit. With Terraform, you define your entire router configuration in simple .tf files, commit them to Git, and apply changes in seconds. Forget clicking through menus or memorizing RouterOS commands — your config becomes code.

✅ Reproducible — spin up identical configs across multiple routers instantly
✅ Version-controlled — track every change in Git like a software project
✅ Self-documenting — your .tf files are your documentation
✅ Disaster-recovery ready — restore your full config in one command
✅ Team-friendly — collaborate on network changes with pull requests and code reviews

👍 Code in the video:
- providers.tf:
terraform {
required_providers {
routeros = {
source = "terraform-routeros/routeros"
version = "⟩= 1.0.0"
}
}
}

provider "routeros" {
hosturl = var.mikrotik_host
username = var.mikrotik_username
password = var.mikrotik_password
insecure = true # Usually set to true unless you've installed a custom SSL cert on the router
}

- variables.tf:
variable "mikrotik_host" {
type = string
description = "The IP address or hostname of the MikroTik router (e.g., 192.168.88.1)"
}

variable "mikrotik_username" {
type = string
description = "The admin username for the MikroTik router"
}

variable "mikrotik_password" {
type = string
description = "The password for the MikroTik router"
sensitive = true
}

variable "new_identity" {
type = string
description = "The new name for your router"
default = "MikroTik-HQ"
}

- main.tf
resource "routeros_system_identity" "my_router" {
name = var.new_identity
}

- credentials.auto.tfvars.tf
mikrotik_host = "192.168.1.x"
mikrotik_username = "admin"
mikrotik_password = "xxxxxx"
new_identity = "MikroTik-HQ"
