Traefik requires access to the docker socket to get its dynamic configuration. Traefik will use the IPv4 container IP before its IPv6 counterpart. When using a docker stack that uses IPv6, The bridge interface ( docker0 by default): -add-host=:172.17.0.1 IPv4 & IPv6 ¶ For example, to set it to the IP address of On Linux, for versions of Docker older than 20.10.0, for to be defined, it should be providedĪs an extra_host to the Traefik container, using the -add-host flag. if that lookup was also unsuccessful, fall back to 127.0.0.1.if the lookup was unsuccessful, try a lookup of, ( Podman equivalent of ).The IP address of the host is resolved as follows: When exposing containers that are configured with host networking, (Read more on this label in the dedicated section in routing). Or does not expose any port, then you must manually specify which port Traefik should use for communicationīy using the label .server.port Then Traefik uses this port for private communication. Traefik retrieves the private IP and port of containers from the Docker API. That is able to define a Docker container with labels can work Ssh_address_or_host=('localhost', tunnel1.Please note that any tool like Nomad, Terraform, Ansible, etc. ) as tunnel1: # tunnel1 is the tunnel between myMachine and gateway1 I believe Local_bind_addresses=, #this line is optional This is how I reproduce it in python: from sqlalchemy import create_engine We cant access gateway2 because only gateway1 is allowed to speak to it. This isn't possible because only gateway2 is allowed to speak to the database. The goal is to access the database by calling my machine on port 33306. I am adding this solution for multiple hops on multiple ports: If the lengths of the lists are the same length, then the IP-addresses / ports will correspond with each other. Here is a modified version of your example 2: import paramiko The singular verisons expects a tuple containing variables for the connections, while the plural versions expects a list of one or more tuple(s). There is the singular versions of bindings ( local_bind_address & remote_bind_address) and the plural versions of bindings ( local_bind_addresses & remote_bind_addresses.
I could use any other Python package that can do the job.īoth examples can be modified slightly to work the way you want. Remote_bind_address=(PRIVATE_SERVER_IP, 22),Ĭt_missing_host_key_policy(paramiko.AutoAddPolicy()) # work with `SECRET SERVICE` through `server.local_bind_port`. Print(server.local_bind_port) # show assigned local port
Python 3 create ssh tunnel to socket how to#
Not sure how to connect multiple servers(2,3,4)Įxample1 from sshtunnel import SSHTunnelForwarder In example1&2, I can only specify one remote&local bind address. I can only access Server2,3, and 4 via server1. I need to forward to multiple ports which are sits behind a server server1(22) -> Server2(mysql, 3360) = local 3360
