You can modify an Exascale VM Cluster in Google Cloud using OCI Terraform provider.

Prerequisites

Terraform or OpenTofu installed
OCI credentials configured
HashiCorp OCI provider version >= 7.0
Exascale VM Cluster is created using Terraform

To modify an Exascale VM Cluster, perform the following steps:

Create a Modify configuration file and add the import block with the Exascale VM Cluster id. The id value can be found at the Create Exascale VM Cluster output block.

Sample Terraform Configuration using OCI Terraform Provider


# Set OCI Provider source and version
terraform {
  required_providers {
    # OCI Provider
    oci = {
      source = "oracle/oci"
      version = "8.12.0"
    }
  }
}

# Configure the OCI Provider
provider "oci" {
  tenancy_ocid = "ocid1.tenancy.oc1..aaaaaaaa2pg53mzroh6r2ub72r5mxxxxxxxxxxxxxpylciiqdihofe3dq" 
  user_ocid = "ocid1.user.oc1..aaaaaaaaa6wyl3kzbgogsqpsixxxxxxxxxxxxxxxxuwzkemcrgue5q" 
  private_key_path = "C:\\OCI-Terraform\\private-key.pem" # This example is for Windows OS
  fingerprint = "6c:c7:a7:60:f2:99:62:b9:8e:01:fc:e8:9b:eb:61:61"
  region = "us-desmoines-1" 
}

# Import Exascale VM Cluster Configuration
import {
    to = oci_database_exadb_vm_cluster.oci_exascale_vm_cluster
    id = "ocid1.exadbvmcluster.oc1.xxx.anuwcljtou6knayanpsxxxxxxxxxxxxxxxj74msrv4t53fkgrrspyxm3ona" # Replace the OCID value
}

Run the following commands in the Terminal window:

terraform init

terraform validate

terraform plan -generate-config-out="C:\GoogleCloud-Terraform\Working-Directory\generated_exascale_vm_cluster.tf" # An example on Windows OS

Open the generated_exascale_vm_cluster.tf file in a text editor and copy the content.
Append the generated_exascale_vm_cluster.tf content in the Modify configuration file. Remove the import block.

Run the following command in the Terminal window:

terraform import oci_database_exadb_vm_cluster.oci_exascale_vm_cluster "ocid1.exadbvmcluster.oc1.xxx.anuwcljtou6knayanpsxxxxxxxxxxxxxxxj74msrv4t53fkgrrspyxm3ona" # Replace the OCID value

Run the following command in the Terminal window to confirm the imported state file and the generated configuration file resources are in sync:
```
terraform plan
```

Update the properties/values in the Modify configuration file as required.

Note

Modifying the configuration of Exascale VM Cluster using OCI Terraform provider will make the Create configuration file out of sync. To avoid out of sync Force replacement / Destroy issue, add the following lifecycle block in the Create configuration file.


lifecycle {
    ignore_changes = [
      properties[0].enabled_ecpu_count_per_node,
      properties[0].additional_ecpu_count_per_node,
      properties[0].vm_file_system_storage[0].size_in_gbs_per_node
    ]
  }
