Question

我无法使用多文件夹卷装载挂载配置图。

volume-mount.yaml的结构如下：

DOESN＆＃39; WORK

apiVersion: v1
kind: Pod
metadata:
  name: test-web
spec:
  containers:
    - name: test-web
      image: docker.io/hello-world    
      volumeMounts:
      - name: config-volume
        mountPath: /usr/test
  volumes:
    - name: config-volume
      configMap:
        name: test-config-map
        items:
       - key: application.properties 
         path: test-web
       - key: test.xml
          path: test-web/configs/test_config
  restartPolicy: Never

错误：

MountVolume.SetUp failed for volume "config-volume" : open /var/lib/kubelet/pods/93768c34-6dc6-11e8-9546-025000000001/volumes/kubernetes.io~configmap/config-volume/..2018_06_11_22_27_08.476420050/test-web: is a directory`

WORKS

apiVersion: v1
kind: Pod
metadata:
  name: test-web
spec:
  containers:
    - name: test-web
      image: docker.io/hello-world    
      volumeMounts:
      - name: config-volume
        mountPath: /usr/test
  volumes:
    - name: config-volume
      configMap:
        name: test-config-map
        items:
       - key: test.xml
          path: test-web/configs/test_config
  restartPolicy: Never

此外，configmap将作为root用户加载，因为我们希望将卷安装作为特定用户进行。

请您告诉我我的yaml文件中可能缺少的内容，以解决上述两个问题。

在你的情况下，这应该很合适：

apiVersion: v1
kind: Pod
metadata:
  name: test-web
spec:
  containers:
    - name: test-web
      image: docker.io/hello-world
      volumeMounts:
      - name: config-volume-1
        mountPath: /usr/test1
      - name: config-volume-2
        mountPath: /usr/test2
  volumes:
    - name: config-volume-1
      configMap:
        name: test-config-map
        items:
        - key: application.properties 
          path: test-web
    - name: config-volume-2
      configMap:
        name: test-config-map
        items:
        - key: test.xml
          path: test-web/configs/test_config
  restartPolicy: Never
