Terraform module to provision a site-to-site VPN connection between a VPC and an on-premises network.
The module does the following:
- Creates a Virtual Private Gateway (VPG) and attaches it to the VPC
- Creates a Customer Gateway (CGW) pointing to the provided IP address of the Internet-routable external interface on the on-premises network
- Creates a Site-to-Site Virtual Private Network (VPN) connection and assigns it to the VPG and CGW
- Requests automatic route propagation between the VPG and the provided route tables in the VPC
- If the VPN connection is configured to use static routes, provisions a static route between the VPN connection and the CGW
This project is part of our comprehensive "SweetOps" approach towards DevOps.
It's 100% Open Source and licensed under the APACHE2.
We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!
IMPORTANT: The master
branch is used in source
just as an example. In your code, do not pin to master
because there may be breaking changes between releases.
Instead pin to the release tag (e.g. ?ref=tags/x.y.z
) of one of our latest releases.
