syncthing 是一個開源檔案同步系統，你可以在服務器上部署一個服務，之後在家和公司部署一個節點，這樣這三個地方的檔案可以自動同步，這比收費的 Dropbox 方案強了不止一點(syncthing 免費，並且容量取決與你服務器的磁盤大小)。這裏有本喵寫的簡介，更多細節建議查看官方文檔。

要使用 compose 部署請參考如下設定

networks:
  ingress_intranet:
    external: true
services:
  ingress:
    image: ${IMAGE_OF_NGINX}
    restart: always
    volumes:
      - ./conf/nginx/nginx.conf:/etc/nginx/nginx.conf:ro
      - ./conf/nginx/snippets:/etc/nginx/snippets:ro
      - ./conf/nginx/conf.d:/etc/nginx/conf.d:ro
    networks:
      default:
      ingress_intranet:
        ipv4_address: ${IP_OF_INGRESS}
  sync:
    image: ${IMAGE_OF_SYNC}
    restart: always
    ports:
      - "22000:22000/tcp"
      - "22000:22000/udp"
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Shanghai
    volumes:
      - /home/king/Sync:/var/syncthing/Sync
      - /opt/data/sync/sync:/var/syncthing/config
  stdiscosrv:
    build: ./conf/stdiscosrv
    restart: always
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Shanghai

sync

service sync 是必須的，它默認在 8384 端口上啓動了網頁 ui，在 22000 端口上開放了數據同步

stdiscosrv

stdiscosrv 是非必須的，它自建了一個發現服務器，你也可以直接使用 sync 官方默認提供的發現服務器，但官方免費的服務肯定沒有你自己提供的速度快

因爲官方沒有爲 stdiscosrv 提供 image，所以需要自己 build

cat conf/stdiscosrv/Dockerfile

FROM ghcr.io/linuxserver/baseimage-ubuntu:focal

RUN set -eux; \
    apt-get update; \
    apt-get install -y --no-install-recommends syncthing-discosrv; \
    rm -rf /var/lib/apt/lists/*

COPY root/ /

EXPOSE 80
VOLUME /data

chmod a+x conf/stdiscosrv/root/etc/cont-init.d/30-config

cat conf/stdiscosrv/root/etc/cont-init.d/30-config

#!/usr/bin/with-contenv bash

# permissions
chown abc:abc \
    /data

chmod a+x conf/stdiscosrv/root/etc/services.d/stdiscosrv/run

cat conf/stdiscosrv/root/etc/services.d/stdiscosrv/run

#!/usr/bin/with-contenv bash

exec \
    s6-setuidgid abc \
    /usr/bin/stdiscosrv -http -listen=':80' -db-dir='/data' -cert='/data/cert.pem' -key='/data/key.pem'

ingress

ingress 不是必須的使用 nginx 創建了反代將 stdiscosrv 和 sync 提供的網頁服務反代到 80 端口供入口網關訪問

server{
    listen 80;
    server_name sync.xxx.xxx;
    location /{
        include snippets/proxy-set.conf;
        proxy_pass http://sync:8384;
    }
}
server{
    listen 80;
    server_name stdiscosrv.xxx.xxx;
    location /{
        include snippets/proxy-set.conf;
        proxy_pass http://stdiscosrv;
    }
}

cat snippets/proxy-set.conf

proxy_send_timeout                      60s;                                  
proxy_read_timeout                      60s;
