I really like what is on offer here - thank you for building it. Re the private network it builds with Wireguard, how are services running within this private network supposed to access AWS services such as RDS securely? Tailscale has this: https://tailscale.com/kb/1141/aws-rds

Thanks! If you're running the ucloud cluster in AWS, service containers should be able to access RDS the same way the underlying EC2 instances can (assuming RDS is in the same VPC or reachable via VPC peering).

The private container IPs will get NATed to the underlying EC2 IPs so requests to RDS will appear as coming from those instances. The appropriate Security Group(s) need to be configured as well. The limitation is that you can't segregate access at the service level, only at the EC2 instance level.
