Networking Vision Example

Introduction

This example shows how to deploy core VCN resources in OCI using the OCI Landing Zone Networking module.

It deploys one basic three-tier VCN with the following resources:

• three subnets: public LBR, private app, and private database;
• three route tables, one to each subnet;
• four network security groups, including a Bastion network security group to allow SSH connections to private subnets;
• one Internet Gateway;
• one NAT Gateway;
• one Service Gateway.

The example outputs a file named vision-network.json, with select resources (VCNs) that can be further used as a dependency in another network configuration example that requires resources managed by this configuration example.
See external-dependency example.

See input.auto.tfvars.template for the network configuration.

See module's README.md for overall attributes usage.

Using this example

1. Rename input.auto.tfvars.template to <project-name>.auto.tfvars, where <project-name> is any name of your choice.

2. Within <project-name>.auto.tfvars, provide tenancy connectivity information and adjust the input variables, by making the appropriate substitutions:

   • Replace <REPLACE-WITH-NETWORK-COMPARTMENT-OCID> placeholder with the network compartment OCID where the VCN is created.
   • Replace <REPLACE-WITH-ALLOWED-CIDR-RANGE> placeholder with the CIDR range allowed to SSH into the Bastion Network Security Group.

3. In this folder, run the typical Terraform workflow:

terraform init
terraform plan -out plan.out
terraform apply plan.out
