ODB Network

An ODB network can be modifed by adding or removing subnets. You can add up to five (5) subnets. For detailed steps on creating subnets, see the Create - ODB Network section.
ODB Network can be modified only from Google Cloud Console or Google Cloud CLI .

ODB Network can be modified only from Google Cloud Console or Google Cloud CLI .

You can modify an ODB Network in Google Cloud by adding or removing subnets using Google Cloud Terraform provider. To add a subnet, append the Terraform configuration file with an ODB Network Subnet resource block.

Prerequisites

Terraform or OpenTofu installed
Google Cloud credentials configured
HashiCorp Google Cloud provider version >= 7.0

Sample Terraform Configuration Using Google Cloud Terraform Provider

# Set Google Cloud Provider source and version
terraform {
  required_providers {
    google = {
      source = "hashicorp/google"
      version = "~> 7.0" # Use the latest major version
    }
    # OCI Provider
    oci = {
      source = "oracle/oci"
      version = "7.29.0"
    }
  }
}

# Configure the Google Cloud Provider
