# Oracle Cloud Infrastructure Default VCN Terraform Module

The Oracle Cloud Infrastructure Default VCN Module creates a basic Oracle Cloud Infrastructure Virtual Cloud Network (VCN) setup that can be used to get started quickly with Oracle Cloud Infrastructure and Terraform. The VCN contains a public subnet in each availability domain, with routing to an internet gateway.

By default, each subnet uses the default security list for the VCN. That default security list has a set of default rules - see [Security Lists](https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/securitylists.htm#default-list) for details. By default, TCP traffic on destination port 22 (SSH) will be open from any source port. This will enable you to easily launch a Linux instance and connect via SSH. However, please note that by default Remote Desktop Protocol, RDP, will not be accessible. If you are using a Windows image, you have to add a stateful ingress rule for TCP traffic on destination port 3389 from any source port. The rules in the default security list can be modified in Terraform by using the `oci_core_default_security_list` resource - see [Default Resources](https://github.com/oracle/terraform-provider-oci/blob/master/docs/Managing%20Default%20Resources.md).

For more information about Oracle Cloud Infrastructure VCNs and networking, see [VCNs and Subnets](https://docs.us-phoenix-1.oraclecloud.com/Content/Network/Tasks/managingVCNs.htm).

## Prerequisites

See the [Oracle Cloud Infrastructure Terraform Provider docs](https://www.terraform.io/docs/providers/oci/index.html) for information about setting up and using the Oracle Cloud Infrastructure Terraform Provider.

## How to use this module

The [examples](./examples/vcn_default) folder contains an example of how to use this module.


To create one VCN using this module:

```hcl
module "vcn" {
  source           = "../../"
  compartment_ocid = "${var.compartment_ocid}"
  vcn_display_name = "${var.vcn_display_name}"
  vcn_cidr         = "${var.vcn_cidr}"
}

```

Argument | Description
--- | ---
compartment_ocid | Unique identifier (OCID) of the compartment in which the VCN is created
vcn_display_name | Dispaly name of Virtual Cloud Network
vcn_cidr |  The CIDR IP address block of the VCN
vcn_dns_label | A DNS label for the VCN, used in conjunction with the VNIC's hostname and subnet's DNS label to form a fully qualified domain name (FQDN) for each VNIC within this subnet
subnet_dns_label | A DNS label prefix for the subnet, used in conjunction with the VNIC's hostname and VCN's DNS label to form a fully qualified domain name (FQDN) for each VNIC within this subnet
