tailscale

两台机器:

curl -fsSL https://tailscale.com/install.sh | sh

连接到控制台 --accept-dns=false : 禁用 Tailscale 的 DNS，用于解决与clash的冲突 --netfilter-mode：自动防火墙开关 https://blog.nipx.cn/pages/17a0b1/#%E8%AE%BE%E7%BD%AEopenwrt

tailscale up --accept-dns=false --accept-routes

启用子网路由;

  • --advertise-routes：声明要暴露的内网网段（根据你的内网调整）。

  • --accept-routes：允许其他节点接收此路由

# 停止现有 Tailscale 服务
sudo tailscale down

# 重新通告 Docker 网络子网（172.18.0.0/16）
sudo tailscale up --advertise-routes=172.18.0.0/16 --accept-routes

# 其他
sudo tailscale up --advertise-routes=172.21.0.0/24 --accept-routes

启用子网转发:

# 重启 Tailscale 并接受路由
sudo tailscale down 
sudo tailscale up --accept-routes

# 检查路由表（应显示 172.18.0.0/16 路由）
ip route show | grep 172.18.0.0
5. 验证网络状态​

在任意节点检查节点列表和路由：

tailscale status

K8s

https://agou-ops.cn/post/%E4%BD%BF%E7%94%A8tailsclae-vpn%E8%AE%BF%E9%97%AEk8s%E9%9B%86%E7%BE%A4%E6%9C%8D%E5%8A%A1via-k8s-operator/

https://tailscale.com/kb/1236/kubernetes-operator#cilium-in-kube-proxy-replacement-mode

如果你在kube-proxy 替换模式下运行 Cilium, 必须在 Pod 的命名空间中启用绕过套接字负载均衡器：

cilium upgrade cilium/cilium \
--namespace kube-system \
--reuse-values \
--set socketLB.hostNamespaceOnly=true

通过Connector公开serviceCIDR 范围。

cat > /home/kubernetes/tailscale/ts-pod-cidrs.yml <<EOF
apiVersion: tailscale.com/v1alpha1
kind: Connector
metadata:
  name: ts-pod-cidrs
spec:
  hostname: ts-pod-cidrs
  subnetRouter:
    advertiseRoutes:
      - "10.40.0.0/14"
EOF
kubectl apply -f ts-pod-cidrs.yml
kubectl get connector ts-pod-cidrs
kubectl describe connector ts-pod-cidrs

其他节点加入

sudo tailscale up --accept-routes

测试:

关键点是上面的注解tailscale.com/expose: "true"，Tailscale operator会自动创建一个对应的statefulset和service

kubectl run kuard -l app=kuard --image 163751/kuard:green
cat > test-kuard.yml <<EOF
apiVersion: v1
kind: Service
metadata:
  name: kuard-tailscale-svc
  annotations:
    tailscale.com/expose: "true"
  labels:
    app: kuard
spec:
  ports:
    - port: 8080
      protocol: TCP
      name: kuard
  selector:
    app: kuard
  type: ClusterIP
EOF
kubectl apply -f test-kuard.yml

cat > kuard-ingress.yml <<EOF
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: kuard-ingress
spec:
  defaultBackend:
    service:
      name: kuard-tailscale-svc
      port:
        number: 8080
  ingressClassName: tailscale
EOF
kubectl apply -f kuard-ingress.yml

访问: 进入到https://login.tailscale.com/admin/machines 然后查询当前svc 的IP

curl http://100.100.22.103:8080

删除

kubectl delete -f test-kuard.yml
kubectl delete -f kuard-ingress.yml

缺点​

可能无法直接与 Clash 等代理使用
