docker connecting to host tunnel from container

docker ssh-tunnel docker-networking docker-container

You missed bind_address, so now your binding address is 127.0.0.1.Setting your tunnel you have to add bind_address parameter.

-L [bind_address:]port:host:hostport

E.g.

sudo ssh -f -N -L 172.17.0.1:5555:localhost:5432 user@remotehost
