Network Tunneling - SSH Port Forwarding

Mission

Practice SSH local port forwarding inside one container. The SSH jump role is 127.0.0.1:22 and the internal service listens only on 127.0.0.1:5432 in that same container. Safely forward it to port 8888 and retrieve its response; no external host or real database is used.
