使用 YAML 的 k3 集群上的 Node Red 不工作
Node Red on my k3 cluster using YAML not working
我正在尝试将一个简单的 node-red 应用程序部署到我的 k3s 容器。背景我有两个 pi 4 作为我的服务器和 3B+ 作为我的工人。
对于我得到的错误

我似乎无法追溯我的日志问题，或者至少不确定去哪里找。欢迎任何帮助
对于那些想知道我让这个工作的人。由于某种原因，它与节点 js 的安装发生冲突......不知道为什么。卸载了 nodejs 并重新安装，一切正常。因此，对于那些想要使用它的人来说，上面的配置文件没有任何问题。将配置绑定到卷后，您也可以添加身份验证。
