Kubernetes上的Spring Cloud数据流部署错误答案

【问题标题】：spring cloud dataflow on kubernetes error on deployKubernetes上的Spring Cloud数据流部署错误
【发布时间】：2023-03-22 03:15:01
【问题描述】：

我正在开发 Spring Cloud 数据流流应用程序。我能够在 Cloud Foundry 中运行船长的情况下运行 Spring 云数据流服务器。现在，我尝试在 kubernetes 集群中运行相同的船长并在部署时遇到错误，即使我在部署的环境配置中明确给出了用户名。

原因：io.fabric8.kubernetes.client.KubernetesClientException：执行失败：GET 在： kubernetes_cluster_url:6443/api/v1/namespaces/pocdev/services?labelSelector=spring-app-id%3Dtest444-pocclient .服务帐户可能已被撤销。服务被禁止：用户 “system:anonymous”无法在 API 组“”中列出资源“服务” 命名空间“poc-dev”。

【解决方案1】：

当我从 env 属性列表中删除以下属性并且船长开始使用默认服务而不是我的用户帐户时，此问题得到了修复

名称：“SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_KUBERNETES_ACCOUNTS_K8S_FABRIC8_USERNAME” 价值： ”” - 名称：“SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_KUBERNETES_ACCOUNTS_K8S_FABRIC8_PASSWORD” 值：“”
