This tutorial guides you through setting up an OpenVPN server in a private AWS VPC to securely access resources, covering infrastructure setup, manual configuration, and automation via scripts and Google Single Sign-On 0:05.
Key Takeaways:
• The AWS infrastructure is configured with a VPC, public and private subnets, an Internet Gateway, and NAT Gateways to provide internet access for resources 0:39.
• The OpenVPN server is installed using official repositories and PKI infrastructure is managed via easy-rsa to generate CA, server, and client certificates 10:06.
• Server configuration pushes specific VPC routes to clients and sets the Route53 private DNS server IP to allow resolution of private hostnames 20:43.
• Client access can be revoked by generating a Certificate Revocation List (CRL) and updating the server configuration to reject revoked clients 31:09.
• The process is fully automated using a Bash script for profile generation and the Gate-SSO project integrated with Docker and Google OAuth for seamless onboarding 36:36.
This complete setup ensures secure access to private AWS resources while minimizing the overhead of manual profile management 51:37.

OpenVPN allows you to create secure point-to-point
or site-to-site connections. In this video, we will use OpenVPN to connect to the
private AWS VPC. We will create a few private and public subnets, and later we
will push those routes to the clients. Also, we will create a private Route53 hosted zone
and push the AWS DNS server to the client. This will allow us to resolve those private
hostnames locally. In the first example, we will create an OpenVPN profile manually. In the
second example, we will create a simple script to automate profile generation. In the last one,
we will use the opensource gate-sso project to use Google single sign-on to automate
client certificate and profile generation. Let's start from scratch. First, we need to
create an AWS Virtual private cloud - VPC.…
