所以这意味着 Node-RED 正在侦听端口 80，这是不允许的，因为用户不是 root。
我认为可以通过配置 node-red 使其不侦听端口 80 而是侦听端口 1880 来修复此错误。我不清楚如何在我想要的特定场景中执行此操作使用 Docker 图像 nodered/node-red-docker:rpi-v8 我想用 resin.io.
部署
我的问题：部署镜像时如何保证Node-RED监听1880端口nodered/node-red-docker:rpi-v8 使用 resin.io ?
- 我注意到我的 raspberry pi 设备的设备服务变量 "PORT" 在 resin.io 中设置为 80。因此，通过将其更改为 1880 来解决此问题。
仅供参考：它设置为 80，因为我已经部署了 https://github.com/resin-io-projects/balena-node-red，为此我必须将端口设置为 80。
- 或者，我们可以通过如下更改 Dockerfile（添加最后 3 行）来允许
node 应用程序侦听任何端口。这种方法的优点是我们可以继续使用端口 80，这意味着我们可以使用 public url 提供的 public url 通过互联网访问 Node-RED 编辑器和 Node-RED ui =13=]
