Kubernetes使用CronJob运行作业

是否有一种方法可以使用CronJob资源运行现有作业。 在CronJob规范模板中，我们可以使用标签应用选择器。大概是这样的：

工作规范：（）

Cron规范：

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: pi-cron
spec:
  schedule: "*/1 * * * *"
  jobTemplate:
    spec:
      labelSelector:
        name: pi # refer to the job created above

我遇到了这个。我想试试这个的倒数。

不，你不能用你想要的方式来做这件事

kubectl

仅允许基于cronjob创建作业，反之亦然

 kubectl create job NAME [--image=image --from=cronjob/name] -- [COMMAND] [args...] [flags] [options]

当前可用于kubectl创建的命令：

  clusterrole         Create a ClusterRole.
  clusterrolebinding  Create a ClusterRoleBinding for a particular ClusterRole
  configmap           Create a configmap from a local file, directory or literal value
  deployment          Create a deployment with the specified name.
  job                 Create a job with the specified name.
  namespace           Create a namespace with the specified name
  poddisruptionbudget Create a pod disruption budget with the specified name.
  priorityclass       Create a priorityclass with the specified name.
  quota               Create a quota with the specified name.
  role                Create a role with single rule.
  rolebinding         Create a RoleBinding for a particular Role or ClusterRole
  secret              Create a secret using specified subcommand
  service             Create a service using specified subcommand.
  serviceaccount      Create a service account with the specified name

只想注意，使用

kubectl

时，您不能在创建时指定--from和command

  clusterrole         Create a ClusterRole.
  clusterrolebinding  Create a ClusterRoleBinding for a particular ClusterRole
  configmap           Create a configmap from a local file, directory or literal value
  deployment          Create a deployment with the specified name.
  job                 Create a job with the specified name.
  namespace           Create a namespace with the specified name
  poddisruptionbudget Create a pod disruption budget with the specified name.
  priorityclass       Create a priorityclass with the specified name.
  quota               Create a quota with the specified name.
  role                Create a role with single rule.
  rolebinding         Create a RoleBinding for a particular Role or ClusterRole
  secret              Create a secret using specified subcommand
  service             Create a service using specified subcommand.
  serviceaccount      Create a service account with the specified name
