zokradonh/ssh-tunnel-server repository overview

⁠SSH tunnel server

SSH server side of a tunnel. Companion for zokradonh/ssh-tunnel-client. Perfect for use between two docker hosts that are not in swarm environment but need encrypted container to container connection.

⁠docker-compose.yml

version: '2'

services:
  tunnel:
    image: zokradonh/ssh-tunnel-server
    restart: always
    networks:
      - othercontainernet
    volumes:
      - ./id_ed25519.pub:/home/tunneluser/.ssh/authorized_keys
    ports:
      - "222:22"


networks:
  othercontainernet:
    external:
      name: othercontainer_default

Replace id_ed25519.pub with filename of your public key.

Replace othercontainer_default with the name of the network that your target container is connected to.

Do not change othercontainernet or change both occurences.
