Kubernetes ConfigMap在有效的YAML中导出“string”

configmap kubernetes

我正试图使用ConfigMap在Kubernetes中设置一个Cron作业,并将一个shell脚本装载到一个卷中。我有有效的YAML,但第9行抛出一个错误,它需要一个字符串:

apiVersion: v1
kind: ConfigMap
metadata:
  name: elasticdump-configmap
  namespace: default
data:
  job.schedule: "*/5 * * * *"
  spec:
    restartPolicy: OnFailure
    containers:
    - name: elasticdump
      image: elasticdump/elasticsearch-dump
      imagePullPolicy: IfNotPresent
      command: ["/bin/sh", "-c", "elasticdump.sh"]
    volumeMounts:
      - mountPath: /opt/data
        name: blob01
    resources:
      requests:
        memory: 1Gi
      limits:
        memory: 5Gi
  volumes:
     - name: blob01
       persistentVolumeClaim:
        claimName: pvc-blob
       configMap:
        name: elasticdump-configmap
        items:
          - key: elasticdump.sh
            path: elasticdump.sh

我知道我在YAML的结构中做了一些错误的事情,但我对Kubernetes还很陌生,所以我希望能提供一些建议。

如中所述 docs :

ConfigMap是一个API对象,用于存储其他要使用的对象。

所以,这样定义CronJob是不可能的。请看特殊的k8s对象 CronJob

apiVersion: batch/v1
kind: CronJob
metadata:
  name: elasticdump-configmap
  namespace: default
spec:
  schedule: "*/5 * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: elasticdump
            image: elasticdump/elasticsearch-dump
            imagePullPolicy: IfNotPresent
            command: ["/bin/sh", "-c", "elasticdump.sh"]
            volumeMounts:
            - mountPath: /opt/data
              name: blob01
            resources:
              requests:
                memory: 1Gi
              limits:
                memory: 5Gi
          volumes:
          - name: blob01
            persistentVolumeClaim:
              claimName: pvc-blob
          - name: elasticdump-configmap
            configMap:
              name: elasticdump-configmap
              items:
              - key: elasticdump.sh
                path: elasticdump.sh
          restartPolicy: OnFailure
