job例子：
apiVersion: batch/v1 ??#job的apiVersionkind: Job ?????????????#资源类型为jobmetadata: ???????????????labels: ???name: busybox ?name: busyboxspec: ?template: ???metadata: ?????name: busybox ???spec: ?????containers: ???????- name: busybox ?????????image: myhub.mingyuanyun.com/library/busybox ?????????command: ???????????- sleep ???????????- "30" ?????restartPolicy: Never ?#什么情况下重启容器，job一般只能设置为Never和OnFailure，一般设置为Never
restartPolicy: Never ?#如果使用参数Never，容器启动后未成功就会一直创建新的容器
restartPolicy: OnFailure ?#如果使用参数OnFailure，容器启动后未成功不会在创建新的容器，他会一直重启
kubectl apply -f myjob.yaml
kubectl get job
kubectl get pod --show-all
kubectl logs busybox
kubectl delete -f myjob.yaml
并行job的创建：
apiVersion: batch/v1 ??kind: Job ???????????metadata: ???????????????labels: ???name: busybox ?name: busyboxspec:
?completions： 6 ?#直到总共有6个pod成功执行 ?如果不指定默认值为1
?parallelism: 2 ??#一次启动2个pod来执行job ?如果不指定默认值为1 ?template: ???metadata: ?????name: busybox ???spec: ?????containers: ???????- name: busybox ?????????image: myhub.mingyuanyun.com/library/busybox ?????????command: ???????????- sleep ???????????- "30" ?????restartPolicy: Never ?
定时job：
apiVersion: batch/v2alpha1 ?#当前CronJob的apiVersionkind: CronJob ???????????#当前类型CronJobmetadata: ???????????????name: testspec: ?schedule: "*/1 * * * *" ?#运行时间，格式与linux一致 ?jobTemplate: ?#job模板 ???spec: ?????template: ????????spec: ???????????containners: ???????????- name: test ?????????????image: nginx ?????????????command: ["echo", "this is test"] ???????????restartPolicy: OnFailure
需要在kube-aoiservier配置文件中添加
kubectl api-version #查看当前所有api-version 是否支持 batch/v2alpha1
kubectl get cronjob
kubernetes ?job的原理
