使用在Minikube上运行的Argo工作流程无法将数据发送到Minio

Question

我在Minikube上测试Argo工作流程，我正在使用Minio上传/下载工作流程中创建的数据。当我提交模板yaml时，我在pod上出现了failed to save outputs错误。

我使用kubectl logs -n air [POD NAME] -c wait检查了日志，结果如下。

有人可以帮忙吗？

Answer 1

你创建minio-credentials秘密，它在运行工作流的命名空间上有secretkey和accesskey？

示例：Argo控制器pod正在argo命名空间上运行。工作流模板在默认命名空间中提交。 minio-credentials secret应该在默认名称空间中可用。
