1、搞定基础镜像：

docker pull openjdk:8-jre-alpine
docker tag openjdk:8-jre-alpine 10.204.82.15/kubernetes/openjdk:8-jre-alpine
docker push 10.204.82.15/kubernetes/openjdk:8-jre-alpine

2、应用打包mvn package

3、编写Dockerfile构建镜像

FROM 10.204.82.15/kubernetes/openjdk:8-jre-alpineCOPY target/cronjob-demo-1.0-SNAPSHOT.jar /cronjob-demo.jarENTRYPOINT ["java", "-cp", "/cronjob-demo.jar", "com.mooc.demo.cronjob.Main"]

docker build -t cronjob:v1 .docker tag cronjob:v1 10.204.82.15/kubernetes/cronjob:v1

 4、编写cronjob.yaml

apiVersion: batch/v1beta1
kind: CronJob
metadata:name: cronjob-demo
spec:schedule: "*/1 * * * *"successfulJobsHistoryLimit: 3suspend: falseconcurrencyPolicy: ForbidfailedJobsHistoryLimit: 1jobTemplate:spec:template:metadata:labels:app: cronjob-demospec:restartPolicy: Nevercontainers:- name: cronjob-demoimage: 10.204.82.15/kubernetes/cronjob:v1

5、容器启动

kubectl apply -f cronjob.yamlkubectl get pods -o wide
