【问题描述】：

我在 Docker 映像中使用 cloudflare 隧道。 docker compose 配置

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，隧道断开。

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

是否有参数可以周期性地重新连接cloudflared客户端？

【参考方案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。

如果您使用这些设置在您的机器上尝试 nativ，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日志的 sn-p：

【讨论】：

似乎 docker 容器中的重新连接过程需要很长时间（最多 30 分钟），但它可以工作
