无法将 argo workflow cron 安装为 helm chart

Question

我想安装一个 argo 工作流模板和工作流 cron 作业作为 helm chart。 helm install 命令说图表已安装。但我看到只有工作流模板被部署，而 cron 作业没有。

文件夹结构：

Argo_helm
 |- templates
     |-azure-migration-cron-etl.yaml
     |-azure-migration-etl-template.yaml
 |-Chart.yaml
 |-values.yaml

执行helm install命令后，如下图

 helm upgrade --install argo-helm-charts --values values.yaml . 

WARNING: Kubernetes configuration file is group-readable. This is insecure. Location: /Users/e192270/.kube/config
WARNING: Kubernetes configuration file is world-readable. This is insecure. Location: /Users/e192270/.kube/config
Release "argo-helm-charts" does not exist. Installing it now.
NAME: argo-helm-charts
LAST DEPLOYED: Mon Feb  8 11:28:01 2021
NAMESPACE: argo
STATUS: deployed
REVISION: 1
TEST SUITE: None

当我列出模板时我可以看到它

$ argo template list   
                                                                                                               
NAME
test-azure-migration

但是无法看到作为图表的一部分安装的 cron

argo cron list -n argo 
NAME              AGE   LAST RUN   NEXT RUN   SCHEDULE      SUSPENDED

Argo 允许您scale vertically by adding multiple workflow controllers。每个控制器都有一个“实例 ID”。

您的 CronWorkflow 指定了 fp 工作流控制器实例。

apiVersion: argoproj.io/v1alpha1
kind: CronWorkflow
metadata:
  name: {{ .Values.workflow_name }}
  namespace: {{ .Values.workflow_namespace }}
  labels:
    workflows.argoproj.io/controller-instanceid: fp

要列出由 fp 工作流控制器实例管理的 CronWorkflows，请使用 --instanceid 参数：

$ argo cron list -n argo --instanceid fp
NAME             AGE   LAST RUN   NEXT RUN   SCHEDULE    SUSPENDED
v-dim-bud-test   3m    N/A        12h        0 1 * * *   false
