Question

我已经安装了1个主节点和2个节点。我已经为POD创建了名称空间。我已经在下面的教程中启动了linux academy提供的Yaml文件 tutorial 但是当我执行命令卷曲时，它不起作用。

[rbo@K8SMaster ~]$ curl 10.244.1.2:80

Yaml文件

apiVersion: v1
kind: Pod
metadata:
  name: examplepod
  namespace: pod-example
spec:
  volumes:
  - name: html
    emptyDir: {}
  containers:
  - name: webcontainer
    image: nginx
    volumeMounts:
    - name: html
      mountPath: /usr/share/nginx/html
  - name: filecontainer
    image: debian
    volumeMounts:
    - name: html
      mountPath: /html
    command: ["/bin/sh", "-c"]
    args:
      - while true; do
         date >> /html/index.html;
         sleep 1;
        done

命令：

    [rbo@K8SMaster ~]$ kubectl get nodes

感谢您的帮助，对不起，我是K8S的新手

我认为curl命令是正确的，但是nginx容器在端口80上没有返回任何内容。确保已创建pvc，并手动检查此目录-> / usr / share / nginx / html（如果它具有index.html），并检查index.html文件是否具有读取权限。
