ip更改后如何重新连接cloudflare隧道

Question

我在 docker 镜像中使用 cloudflare 隧道。 docker compose 配置看起来像

tunnel:
    image: cloudflare/cloudflared:2021.11.0
    command: tunnel --config /etc/cloudflared/config.yml --no-autoupdate run

和 cloudflared 配置

url: http://host.docker.internal:8000
tunnel: ***
credentials-file: /etc/cloudflared/***.json

当我切换主机 wifi 网络时，主机 ip 发生变化并且隧道断开。

cloudflared tunnel info <NAME>
...
This tunnel has no active connectors.

是否有一个参数可以定期重新连接

cloudflared

客户端？

Answer 1

似乎您的 docker 容器无法识别任何更新或 ip4 更改，因为您在虚拟 docker 交换机上运行它。

如果你在你的机器上尝试使用这些设置，这应该可以工作：

# run command
$ cloudflared tunnel --no-chunked-encoding run <<your_tunnel_name>>

# config.yml in your default cloudflared folder (~/.cloudflared/):

tunnel: 0000001
credentials-file: .cloudflared/0000001.json
originRequest: # Root-level configuration
  connectTimeout: 10s
loglevel: debug
transport-loglevel: debug

ingress:
  - hostname: example.com
    service: http://localhost:4300
    originRequest:
      connectTimeout: 10s
      tcpKeepAlive: 12s
  - service: http_status:404

这里是重新创建新连接后的日志片段：
