Create container from Docker file

This repository already has a docker-compose.yml so you just need to run docker-compose up -d --build

Create container from Github container registry

version: "3.8"

services:
  open-ssh-server:
    image: ghcr.io/pnlinh-it/ssh-tunnel-server:latest
    container_name: ssh-tunnel-server
    restart: unless-stopped
    environment:
      PUBLIC_KEY: "${PUBLIC_KEY}"
    ports:
      - "2223:22"

Nginx proxy and let's encrypt SSL

If you use nginx-proxy and acme-companion, you can consider below compose file:

version: "3.8"

services:
  open-ssh-server:
    image: ghcr.io/pnlinh-it/ssh-tunnel-server:latest
    container_name: open-ssh-server
    restart: unless-stopped
    environment:
      PUBLIC_KEY: "${PUBLIC_KEY}"
      VIRTUAL_HOST: <your_domain>
      LETSENCRYPT_HOST: <your_domain>
    networks:
      - tunnel
      - nginx-proxy
    ports:
      - "2223:22"
    expose:
      - "80"

networks:
  tunnel:
    driver: bridge
    name: tunnel

  nginx-proxy:
    external: true
    name: nginx-proxy
