Docker container to setup a robust ssh tunnel using AutoSSH.
This image has only 100 ports exposed - 10000 to 100100. Having more ports exposed seemed to create a significant slow down in docker ps, portainer, and android docker apps when using multiple containers.
Example docker-compose file:
version: '3'
services:
autossh:
image: autossh-tunnel # beastarman/autossh-tunnel
container_name: autossh-tunnel
ports:
- 10001:10001
volumes:
- autossh-data:/data # point volume or path to location of ssh keys for the tunnel host
#
environment:
- TUNNELUSER=ubuntu
- TUNNELHOST=123.123.123.123 # IP Address or hostname of host
- TUNNELPORT=22
- LOCALPORT=10001 # use between 10001-10100
- REMOTEHOST=localhost
- REMOTEPORT=12345 # amend to the port of the remote service to tunnel to
#
- KEY=keyfilename
#
