Create an HCP Virtual Network

A HashiCorp Virtual Network (HVN) is a logical representation of a subnet in AWS that defines a IPv4 CIDR block. The platform uses this CIDR range to automatically create a virtual private cloud (VPC).

Requirements

• The CIDR block value must be a private IPv4 CIDR block within the RFC1918 address space.
• A CIDR block value must end between /16 and /25.
• CIDR block names must be unique within a project.
• You can create a maxiumum of 5 HVNs within an organization.
• HVN CIDR blocks should not overlap with your external networks CIDR blocks (e.g AWS, Azure).

Considerations

• Each HVN reserves 5 IP addresses for network services.
• Each HCP Vault Dedicated cluster uses 12 IP addresses: 6 for Vault nodes, and 6 for load balancing services.
• You can create up to 6 clusters per organization (primary and cross-region DR).
• You can create up to 5 performance secondary clusters per orgnaization.
• Primary clusters can share an HVN with other primary clusters.
• Cross-region DR and performance replication clusters must use a separate HVN from their primary cluster.

Refer to the service quotas documentation for addtional information.

Create a HVN for AWS

1. Sign in to the HCP Portal and select your organization and project.

2. From the left navigation menu, click HashiCorp Virtual Network.

3. Click Create network.

4. Name your virtual network.

5. Select Amazon Web Services as your provider.

6. Select a region from the dropdown menu.

   • One HVN can be created in each available cloud region.
   • Resources added to the HVN later are added in the same region.

7. (Optional) Specify a CIDR block. Click Show recommendations for more information.

   Recommended practice for HCP administrators

   Use a unique CIDR block for each HVN and ensure HVN CIDR blocks do not overlap with subnets in your AWS account.

8. Click Create network.

Refer to the HVN for AWS documentation for more information.

Create a HVN for Azure

1. Sign in to the HCP Portal and select your organization.

2. From the left navigation menu, click HashiCorp Virtual Network.

3. Click Create network.

4. Name your virtual network.

5. Select Microsoft Azure as your provider.

6. Select a region from the dropdown menu.

   • One HVN can be created in each available cloud region.
   • Resources added to the HVN later are added in the same region.

7. (Optional) Specify a CIDR block. Click Show recommendations for more information.

   Recommended practice for HCP administrators

   Use a unique CIDR block for each HVN and ensure HVN CIDR blocks do not overlap with VNets in your Azure account.

8. Click Create network.
