In this lesson, we will deploy and destroy an Oracle Kubernetes Engine (OKE) Basic Cluster using OpenTofu. We begin by running tofu init, which initializes the Terraform environment and downloads necessary provider plugins. Next, we use tofu apply, referencing our terraform.tfvars file to authenticate with Oracle Cloud Infrastructure (OCI) and deploy resources.

  • How to create a baseline Azure Virtual Network with Terraform/OpenTofu.
  • How CIDR ranges, subnet boundaries, and security defaults shape the platform contract.
  • How to validate the first networking building block before adding workloads.
