我发现在我的测试中，如果加了hostPath.type: Directory，就会报如上的错误，我也百度了一下，说把type: Directory去掉就行了。
如下是我的yaml文件

apiVersion: v1
kind: Pod
metadata:
  name: alpine
  namespace: test
spec:
  initContainers:
    - name: download
      image: harbor.magedu.net/baseimages/alpine
      command: [ "/bin/sh","-c" ]
      args: [ "wget http://www.baidu.com -O /workdir/index.html" ]
      volumeMounts:
        - name: workdir
          mountPath: /workdir
  containers:
    - name: web
      image: harbor.magedu.net/pub-images/nginx-base:v1.18.0
      ports:
        - containerPort: 80
          hostPort: 8080
      volumeMounts:
        - name: workdir
          mountPath: /usr/share/nginx/html
  volumes:

      hostPath:

        path: /workdir
