A hub-and-spoke network (often called star topology) has a central component (the hub) that's connected to multiple networks around it, like a wheel. Implementing this topology in the traditional data center can be costly. But in the Oracle Cloud, there’s no extra cost.
For details of the architecture, see Set up a hub-and-spoke network topology.
managethe following types of resources in your Oracle Cloud Infrastructure tenancy:
Quota to create the following resources: 3 VCNS, 3 subnets, and 1 compute instance.
Deploy Using Oracle Resource Manager
If you aren't already signed in, when prompted, enter the tenancy and user credentials.
Review and accept the terms and conditions.
Select the region where you want to deploy the stack.
Follow the on-screen prompts and instructions to create the stack.
After creating the stack, click Terraform Actions, and select Plan.
Wait for the job to be completed, and review the plan.
To make any changes, return to the Stack Details page, click Edit Stack, and make the required changes. Then, run the Plan action again.
If no further changes are necessary, return to the Stack Details page, click Terraform Actions, and select Apply.
Deploy Using the Terraform CLI
Clone the Module
Create a local copy of this repository:
git clone https://github.com/oracle-quickstart/oci-arch-hub-spoke.git cd oci-arch-hub-spoke ls
Set Up and Configure Terraform
Complete the prerequisites described here.
terraform.tfvarsfile, and specify the following variables:
# Authentication tenancy_ocid = "<tenancy_ocid>" user_ocid = "<user_ocid>" fingerprint = "<finger_print>" private_key_path = "<pem_private_key_path>" # Region region = "<oci_region>" # Availablity Domain availablity_domain_name = "<availablity_domain_name>" # Compartment compartment_ocid = "<compartment_ocid>"
Create the Resources
Run the following commands:
terraform init terraform plan terraform apply
Destroy the Deployment
When you no longer need the deployment, you can run this command to destroy the resources:
