Is it possible to assign a static IP egress for release command instances?
Situation: I have an RDS database that I am connected to from Fly. Previously, I used wireguard peering to do this. However, I am seeing unexplained high wireguard latency and so I’m cutting this out of the equation.
Problem: I do not want my RDS to have open access. Preferably, it’s only connectable via my app’s servers. I can assign static egress IPv4 for machine instances, but then the release command will still be from an unknown IP.
Is there a better solution to avoid having public accessible RDS instance, and to not use Wireguard?
