I've been working with AWS SAM Local to create and test a lambda / api gateway stack before shipping it to production. I have recently ran into a brick wall when trying to access private resources (RDS) when testing locally (sam local start-api --profile [profile]
). I'm able to connect to some of these private resources if I do some ssh tunneling, but was wondering if I am able to test locally without tunneling using VPC.
Below is an example sam template:

After reading through a lot of documentation and searching stackoverflow for anything that would help... I ended up joining the #samdev slack channel and asked for help. I was provided some guidance and a great guide on setting up OpenVPN on an EC2 instance.
The set up was super easy (completed in under 30 minutes) and the EC2 instance uses a pre-baked AMI image. Make sure you assign the new EC2 instance to the appropriate VPC containing the resources you need access to.
Here is a link to the OpenVPN guide: https://openvpn.net/index.php/access-server/on-amazon-cloud.html
