使用Kubernetes启动ProFtpd：发布安装卷

Question

我想使用带有docker image的minikube运行lalal FTP服务器ProFtpd：vipconsult / proftpd

这是我的部署文件：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  annotations:
    reloader.stakater.com/auto: "true"
  name: ftp-local
  namespace: influx
  labels:
    app: ftp-local
    component: core
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: ftp-local
        component: core
    spec:
      initContainers:
      containers:
      - image: vipconsult/proftpd
        name: ftp-local
        imagePullPolicy: IfNotPresent
        # env:
        resources:
          # keep request = limit to keep this container in guaranteed class
          limits:
            cpu: 100m
            memory: 100Mi
          requests:
            cpu: 100m
            memory: 100Mi
        env:
          - name: USERNAME
            value: test
          - name: PASSWORD
            value: test
        volumeMounts:
        - name: ftp-persistent-storage
          mountPath: /var/lib/ftp

      volumes:
      - name: ftp-persistent-storage
        persistentVolumeClaim:
          claimName: ftp-storage

和卷文件：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ftp-storage
  namespace: influx
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  claimRef:
    namespace: influx
    name: ftp-storage
  hostPath:
    path: /data/ftp/storage
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: ftp-storage
  namespace: influx
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

部署时，我有：

➜  proFTP git:(master) ✗ kubectl logs -n influx ftp-local-58d5d774d-zdztf                
chown: cannot access '/etc/proftpd/ftpd.passwd': No such file or directory

文档说明：

  

使用户与主机或数据-v /home/docker/proftpd/ftpd.passwd:/etc/proftpd/ftpd.passwd永久共享密码文件

因此，我尝试挂载此文件：

部署（仅显示音量部分）

 volumeMounts:
        - name: ftp-persistent-storage
          mountPath: /var/lib/ftp
        - name: ftp-persistent-users
          mountPath: /etc/proftpd/ftpd.passwd
          subPath: ftpd.passwd          

      volumes:
      - name: ftp-persistent-storage
        persistentVolumeClaim:
          claimName: ftp-storage
      - name: ftp-persistent-users
        persistentVolumeClaim:
          claimName: ftp-storage-users

和数量：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ftp-storage
  namespace: influx
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  claimRef:
    namespace: influx
    name: ftp-storage
  hostPath:
    path: /data/ftp/storage
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: ftp-storage-user
  namespace: influx
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  claimRef:
    namespace: influx
    name: ftp-storage-user
  hostPath:
    path: /data/ftp/config
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: ftp-storage
  namespace: influx
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: ftp-storage-user
  namespace: influx
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

首先让我为单个文件使用1GB的卷而感到沮丧，然后得到：

➜  proFTP git:(master) ✗ kubectl logs -n influx ftp-local-67cfd77497-7rt5m                
2019-10-03 07:35:23,853 ftp-local-67cfd77497-7rt5m proftpd[1]: mod_auth_file/1.0: unable to use AuthUserFile '/etc/proftpd/ftpd.passwd': Is a directory
2019-10-03 07:35:23,853 ftp-local-67cfd77497-7rt5m proftpd[1]: fatal: AuthUserFile: unable to use /etc/proftpd/ftpd.passwd: Is a directory on line 193 of '/etc/proftpd/proftpd.conf'

这是我的书卷

   git:(devops) ✗ kubectl get pv,pvc -n influx

现在描述PV：

我在做什么错了？
