一、新建.net core 控制台程序：k8scron.job

 二、将发布程序拷贝到服务器：/root/k8swwwroot/k8scron.job

 三、编辑yaml文件k8scron-job-cron.yaml，每分钟执行一次

apiVersion: batch/v1beta1
kind: CronJob
metadata:
 name: k8scron-job-cron
 namespace:  default
 labels:
    name: k8scron-job-cron
spec:
  schedule: "*/1 * * * *"
  suspend: false
  concurrencyPolicy: Forbid 
  startingDeadlineSeconds: 1000  
  jobTemplate:
   spec:
    template:
      metadata:
        labels:
          app: k8scron-job-cron
      spec:
        restartPolicy: OnFailure
        containers:
        - name: k8scron-job-cron
          image: mcr.microsoft.com/dotnet/sdk:6.0
          command: ["/bin/sh"]
          args: ["-c", "echo 'VERSION-20200122175650';cd /mnt/k8scron.job;dotnet k8scron.job.dll"]
          volumeMounts:
          - mountPath: /etc/localtime
            name: volume-localtime
          - mountPath: /mnt/k8scron.job
            name: data
          - mountPath: /mnt/cert
            name: cert
          resources:
            requests:
                memory: "384Mi"
                cpu: "50m"
            limits:
                memory: "1024Mi"
                cpu: "1000m"                                
        volumes:
        - name: volume-localtime
          hostPath:
            path: /etc/localtime
        - name: data
          hostPath:
            path: /root/k8swwwroot/k8scron.job
        - name: cert
          hostPath:
            path: /root/k8swwwroot/cert

四、部属 

kubectl apply -f k8scron-job-cron.yaml 

附：部属为web
