Terraform : Oracle Cloud Infrastructure (OCI) Compartment

This article describes how to create a compartment on Oracle Cloud Infrastructure (OCI) using Terraform.

Related articles.

Create Working Directory

Create a new working directory and switch to that directory.

mkdir \git\oraclebase\terraform\oci\oci_compartment
cd \git\oraclebase\terraform\oci\oci_compartment

In a previous article (here) we discussed the creation of an OCI provider. Copy the OCI provider information into this new working directory.

copy \git\oraclebase\terraform\oci\oci_provider\*.tf .
copy \git\oraclebase\terraform\oci\oci_provider\*.tfvars .

oci_compartment.tf

Create a file called "oci_container.tf" with the following contents.

# Variables
variable "compartment_name" { type = string }
variable "compartment_desc" { type = string }


# Resources
resource "oci_identity_compartment" "tf_compartment" {
  # Required
  compartment_id = var.root_compartment_id
  description    = var.compartment_desc
  name           = var.compartment_name
}


# Outputs
output "compartment_name" {
  value = oci_identity_compartment.tf_compartment.name
}

output "compartment_id" {
  value = oci_identity_compartment.tf_compartment.id
}

The file begins with variable definitions. We could set default values for these variables, or use literal values directly in the provider definition, but we don't want sensitive information checked into version control, so it makes sense to separate out variable values from the script. The resources section defines the compartment using the input variables. The outputs section allows us to see information about the compartment that's been created, including the ID of the compartment.

The variables, resources and outputs sections can be split into separate files if you find that organisation easier. It may help for more complex definitions.

The root_campartment_id parameter is not defined here, as it's already defined in the oci_provider.tf file.

The full list of parameters and outputs available can be found here.

oci_compartment_variables.auto.tf

There are a number of ways to supply values for input variables. In this example we'll use a ".tfvars" file. We won't check this script into version control as it contains sensitive information.

Create a file called "oci_compartment_variables.auto.tfvars" with the following contents. Adjust the values to match your desired compartment details.

compartment_name = "obcomp2"
compartment_desc = "Oracle-Base Compartment 2"

Build the OCI Compartment

Initialize the working directory using the terraform init command.

terraform init

Use the terraform plan command to test the execution plan.

terraform plan

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # oci_identity_compartment.tf_compartment will be created
  + resource "oci_identity_compartment" "tf_compartment" {
      + compartment_id = "ocid1.tenancy.oc1..aaaaaaaa..."
      + defined_tags   = (known after apply)
      + description    = "Oracle-Base Compartment 2"
      + freeform_tags  = (known after apply)
      + id             = (known after apply)
      + inactive_state = (known after apply)
      + is_accessible  = (known after apply)
      + name           = "obcomp2"
      + state          = (known after apply)
      + time_created   = (known after apply)
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Changes to Outputs:
  + compartment_id   = (known after apply)
  + compartment_name = "obcomp2"

------------------------------------------------------------------------

Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.

Use the terraform apply command to create the OCI compartment.

terraform apply


An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # oci_identity_compartment.tf_compartment will be created
  + resource "oci_identity_compartment" "tf_compartment" {
      + compartment_id = "ocid1.tenancy.oc1..aaaaaaaa..."
      + defined_tags   = (known after apply)
      + description    = "Oracle-Base Compartment 2"
      + freeform_tags  = (known after apply)
      + id             = (known after apply)
      + inactive_state = (known after apply)
      + is_accessible  = (known after apply)
      + name           = "obcomp2"
      + state          = (known after apply)
      + time_created   = (known after apply)
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Changes to Outputs:
  + compartment_id   = (known after apply)
  + compartment_name = "obcomp2"

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

Outputs:

compartment_id = "ocid1.compartment.oc1..aaaaaaaa..."
compartment_name = "obcomp2"

Check the Oracle Cloud account to see the new compartment.
