Sample Terraform Scripts for Provisioning Resources

Use Terraform scripts to provision resources in Fleet Application Management.

In the following sample package:

  • instance_compartment_id: Specifics the compartment , where the Compute instance starts.
  • subnet_id: Specifies a subnet in VCN. See VCN and Subnet Management.
  • display_name: Specifies a display name of the instance.
  • availability_domain: Specifies a domain to place the Compute instance in. To get the specific names of your tenancy's availability domains, run the ListAvailabilityDomains operation or find the Availability domain names when creating an instance using the Console.

variables.tf

This file creates several variables that are used to provision resources. It defines the variables that are used in the Terraform configuration.

variable "compartment_id" {
  type        = string
  description = "OCID of compartment for Compute Instance"
}

variable "subnet_id" {
  type        = string
  description = "OCID of the subnet for Compute Instance"
}

variable "display_name" {
  type        = string
  description = "Display Name Of Compute Instance"
  default = "Test Instance"
}

variable "availability_domain" {
  type = string
  description = "Region based Availability Domain to place the Compute Instance"
}

variable "image_id" {
  type        = string
  description = "Image Id"
}

main.tf

This file contains the Terraform code to provision resources in OCI.
