Terraform on OCI: Automating ARM VMs
Oracle Cloud Free Tier OCI offers free ARM instances with up to 4 OCPUs and 24GB of RAM. Combined with Terraform, we get free and reproducible cloud infrastructure. Terraform Module resource "oci_core_instance" "arm_vm" { availability_domain = data.oci_identity_availability_domain.ad.name compartment_id = var.compartment_id display_name = "arm-instance" shape = "VM.Standard.A1.Flex" shape_config { ocpus = 2 memory_in_gbs = 12 } source_details { source_type = "image" source_id = var.image_id } } Automation The provisioning script configures the node automatically: Installs base dependencies Configures networking Joins the node to the Consul/Nomad cluster Result Cloud infrastructure deployed in minutes, versioned in git, and easily reproducible.
