Terraform Trivadis LAB Host for OCI

Introduction

A reusable and extensible Terraform module that provisions a Trivadis LAB Host for Oracle Cloud Infrastructure

It creates the following resources:

• A compute instance for a given VCN
• Optional n-number of hosts for multiple VCNs. This is used to build several identical environments for a training and laboratory environment.

The module can be parametrized by the number of participants. This will then create n numbers of hosts.

Prerequisites

• An OCI account
• Install Terraform
• Create a Terraform Configuration

HINT This terraform module does use count to create multiple identical resources. Due to this at least Terraform version 0.13.0+ is required.

Quickstart

The module is available in Terraform registry. You may either us it via registry or clone terraform-oci-tvdlab-compute from github.

Add the module to the main.tf with the mandatory parameter. Whereby the host_subnet does expect a list of subnet IDs where to create the hosts. Ideally create with the terraform module tvdlab-vcn.

module "tvdlab-compute" {
  source  = "Trivadis/tvdlab-compute/oci"
  version = ">= 1.0.0"

  # - Mandatory Parameters --------------------------------------------------
  tenancy_ocid          = var.tenancy_ocid
  region                = var.region
  compartment_id        = var.compartment_id
  ssh_public_key_path   = var.ssh_public_key_path
  host_subnet           = module.tvdlab-vcn.private_subnet_id
}

To create multiple hosts in different VCNs just specify the tvd_participants parameter. The following example will create 3 hosts in the provided subnets. It is expected that host_subnet contains 3 different subnets.

module "tvdlab-compute" {
  source  = "Trivadis/tvdlab-compute/oci"
  version = ">= 1.0.0"

  # - Mandatory Parameters --------------------------------------------------
  tenancy_ocid          = var.tenancy_ocid
  region                = var.region
  compartment_id        = var.compartment_id
  ssh_public_key_path   = var.ssh_public_key_path
  host_subnet           = module.tvdlab-vcn.private_subnet_id
  tvd_participants      = 3
}

The module can be customized by a couple of additional parameter. See variables for more information about customisation. The folder examples does contain an example files for main.tf, variables.tv and terraform.tfvars.
