k8s cronjob应用示例

前面部署的elk+filebeat产生的日志太多，容易撑爆磁盘，所以就添加一个cronjob定时清理一定时间以前的索引，如下：

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: es-clean-cronjob
  namespace: kube-system
spec:
  jobTemplate:
    metadata:
    spec:
      template:
        metadata:
        spec:
          containers:
          - command:
            - sh
            - -c
            - curl -XDELETE http://elasticsearch-master.kube-system.svc.cluster.local:9200/filebeat-`date
              -d '-7 day' +%Y.%m.%d`
            image: curlimages/curl:latest
            imagePullPolicy: Always
            name: es-clean-cronjob
          restartPolicy: OnFailure
  schedule: 00 04 * * *
