How to access load balancer url from external server #7

Open EugeneFinch opened 11 months ago

EugeneFinch commented 11 months ago

It appears the said deployment creates a private load balancer which is not accessible from a third-party server (not AWS). Is it possible to amend repository to make it possible to access it externally? currently a blocker for us.

Hi @EugeneFinch ,

the resources in the provided stack are all restricted to the VPC including DNS resolution via Rout53 private hosted zone. There are different ways to extend such a solution, e.g. via reusing the same VPC and adapting the security groups.

The recommended way would be to create a VPC for all blockchain node related workloads and use VPC Private Link (https://aws.amazon.com/privatelink/) to connect these VPCs without having any information being exposed to pubic internet. You can then expose the required resources via security groups.

Let me know if that helps.
