Syncthing是一个开源文件同步工具，可以在多台设备之间实时同步文件或文件夹，官方网站：https://syncthing.net/ 下载地址：https://syncthing.net/downloads/ ，如果是windows一般推荐下载图形界面SyncTrayzor, 但我这边都是linux,就用k8s+docker了。

1、先贴上k8s的，因为这是云端的master服务器

apiVersion: apps/v1
kind: Deployment
metadata:
  name: syncthing
  labels:
    app: syncthing
spec:
  replicas: 1
  selector:
    matchLabels:
      app: syncthing
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: syncthing
    spec:
      containers:
        - env:
            - name: PGID
              value: "1000"
            - name: PUID
              value: "1000"
            - name: TZ
              value: '"Asia/Shanghai"'
          image: linuxserver/syncthing:1.23.2
          name: syncthing
          ports:
            - containerPort: 8384
            - containerPort: 22000
            - containerPort: 22000
              protocol: UDP
            - containerPort: 21027
              protocol: UDP
          resources: {}
          volumeMounts:
            - mountPath: /var/syncthing
              name: syncthing-data
      restartPolicy: Always
      volumes:
        - name: syncthing-data
          nfs:
            server: 172.30.0.15
            path: /data/nfs/syncthing
---
apiVersion: v1
kind: Service
metadata:
  labels:
    app: syncthing
  name: syncthing
spec:
  ports:
    - name: "8384"      # web管理页面
      port: 8384
      targetPort: 8384  
    - name: "22000"     # 服务器同步发现端口，文件也通过这个端口传输
      port: 22000
      targetPort: 22000
    - name: 22000-udp
      port: 22000
      protocol: UDP
      targetPort: 22000
    - name: "21027"
      port: 21027
      protocol: UDP
      targetPort: 21027
  selector:
    app: syncthing
  type: NodePort
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: syncthing-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  tls:
    - hosts:
        - 'syncthing.xxx.com'
      secretName: syncthing-tls
  rules:
    - host: syncthing.xxx.com
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: syncthing
                port:
                  number: 8384

2、再贴上docker的，这是slave

docker run --name syncthing -d --restart always -p 8384:8384 -p 22000:22000 -p 21027:21027 \ -e PGID='1000' -e PUID='1000' -e TZ='Asia/Shanghai'  \
 -v /home/admin/docker_data/syncthing/data:/var/syncthing -v /home/admin/docker_data/syncthing/app:/app linuxserver/syncthing:1.23.2

3、保持网络通畅，然后添加设备，共享文件夹就是了
