kandi X-RAY | autossh Summary
autossh is a program to start a copy of ssh and monitor it, restarting it as necessary should it die or stop passing traffic. The original idea and the mechanism were from rstunnel (Reliable SSH Tunnel). With version 1.2 the method changed: autossh now uses ssh to construct a loop of ssh forwardings (one from local to remote, one from remote to local), and then sends test data that it expects to get back. (The idea is thanks to Terrence Martin.). With version 1.3, a new method is added (thanks to Ron Yorston): a port may be specified for a remote echo service that will echo back the test data. This avoids the congestion and the aggravation of making sure all the port numbers on the remote machine do not collide. The loop-of -forwardings method remains available for situations where using an echo service may not be possible.

QUESTION
I have a plumber service and use dockercloud/haproxy for load balancing. I use docker-compose for running my Docker applications:

...ANSWER
Answered 2021-Jul-28 at 16:36I basically followed the instructions by David (see comments above) and at From inside of a Docker container, how do I connect to the localhost of the machine?

- Establish SSH tunnel with
ssh -L 172.17.0.1:9999:localhost:27017 @ -vN -p22
- In my plumber R script I changed the Mongo URL to
mongo(...url = "mongodb://172.17.0.1:9999"...)
No network_mode: host
is needed.
