Gateways overview
SSH gateway and HTTPS gateway: reach machines without public IP addresses.
Why gateways
Typical clouds give each machine a public IP and open ports 22, 80, and 443 to the internet.
In microsrv, VMs have no public IP. The only things reachable from outside are the gateways:
1. PUBLIC INTERNET INGRESS
[INGRESS] Public packets arrive at edge gateway mesh (zero public IP exposed on VMs)
- SSH gateway —
ssh -A <vm>@msrv.space. - HTTPS gateway — publish a service at
https://<vm>.msrv.space. - WireGuard gateway — join the VPC from a laptop or another cluster.
What you get
- No public IPv4 fee per machine.
- Guest port 22 is closed from the internet.
- Hostnames
<vm>.msrv.spaceget TLS immediately; the HTTPS gateway renews the certificate.
