I have a GCP internal load balancer running on private VPC subnet subnet-a of a project project-a . I have a dns associated to this internal load balancer and it points to a private IP adress of subnet-a.
I want to access that DNS from another project project-b. I created a VPC subnet subnet-b on that project and I peered it to subnet-a. That works fine, I can ping internal addresses from subnet-a without issues.
But, I can't figure out how to access the internal DNS from subnet-a internal load balancer. Is there a way that will make me reach that internal DNS from a browser ?
You have deployed an private project on GCP, only accessible from this project (VPC A). You have created a project B, with a VPC B and peered it with the project A. You can access from the project B, to the project A thanks to the private link (the peering)
Now, from your browser, running on your workstation, you need to set up the same thing: A private link from your workstation to the project A. For that, you need to create a VPN between your workstation (or your network) to the project A VPC. If you are in a company and you need a strong bandwidth, you can also set up a partner interconnect or a dedicated interconnect.
In an cases, you can't directly access from the PUBLIC internet, to your PRIVATE deployment without doing something; it's the principle, keeping private the private things. You can access them only if you open a door: A VPN/interconnect connexion, a bastion, an external load balancer, a proxy,...
