Zero-Port Exposure: Route On-Prem Traffic Via Cloud VM Without Opening Firewalls

By PulseAugur Editorial · [1 sources] ·

This article details a method for exposing on-premises Kubernetes clusters to the public internet without opening firewall ports. The technique, dubbed "Zero-Port Exposure," utilizes Fast Reverse Proxy (FRP) to create outbound tunnels from the cluster to a cloud VM. This cloud VM, running Nginx Proxy Manager and an FRP server, handles TLS termination and forwards traffic into the cluster. This approach offers a cost-effective solution for startups needing public HTTPS endpoints while maintaining security by never exposing the cluster's direct IP. AI

IMPACT Enables cost-effective public access to self-hosted AI/ML infrastructure.
