Nginx-Cloudflare示例运行失败

[MikeWang000000]

这个和 Natter 关系不大，看起来是 Docker 或者是操作系统的问题。

首先先测试下您的 Docker 是否能正常创建网络：

docker network create test_net
docker network rm test_net

如果上面命令失败了，先排查 Docker 出现的故障吧。

另外为了方便定位问题，麻烦提供下相关版本号：

uname -a
cat /etc/os-release
iptables --version
docker version

确实是我的系统问题，以下是我可以查到的信息：

1. 系统版本：
   Linux AS6704T-5FDB 5.13.x #1 SMP Wed Mar 13 00:11:10 CST 2024 x86_64 GNU/Linux

2. iptables version：

iptables v1.8.4 (legacy)

3. 运行docker network create test_net：

Error response from daemon: Failed to program FILTER chain: iptables failed: iptables --wait -I FORWARD -o br-3e42f43f0721 -j DOCKER: iptables v1.8.4 (legacy): Couldn't load target `DOCKER':No such file or directory

Try `iptables -h' or 'iptables --help' for more information.
 (exit status 2)
root@AS6704T-5FDB:/volume1/natterISO # docker network create test_net

Try `iptables -h' or 'iptables --help' for more information.
 (exit status 2)

4. docker版本：

不知道什么原因，你的系统缺少了 Docker 相关的 chain。
如果是 NAS 专用操作系统，可以向有关厂商提单。

不过，可以尝试通过下面的方式手动补回来。

iptables -t filter -N DOCKER
iptables -t filter -N DOCKER-ISOLATION-STAGE-1
iptables -t filter -N DOCKER-ISOLATION-STAGE-2
iptables -t filter -N DOCKER-USER
iptables -t nat -N DOCKER

另外，也可以规避创建网络，就是在 docker-compose.yml 里加上 network_mode: bridge。

感谢回复，按照大佬的方法尝试手补，提示nat已存在，于是又运行了一次docker compose up，成功了（虽然不知道咋回事）。

但在成功运行的log中有一行/usr/bin/env: ‘python3\r’: No such file or directory，服务端口可以正常访问，不知这个抛出有何影响？

原因是：你使用的是Windows的记事本编辑的脚本文件。
换行符格式与Linux不兼容。

请删除这个脚本，使用专用代码编辑器例如：VSCode, Notepad3 等，根据原文件重新修改。
