Kubernetes上的Spring Cloud Dataflow部署时出现错误

问题描述

我正在开发Spring Cloud Dataflow Stream应用程序.我能够使用Cloud Foundry中运行的船长来运行Spring云数据流服务器.现在，即使我在部署中的环境配置中明确给出了用户名，我仍试图与在kubernetes集群中运行的船长运行相同的代码，并在部署时遇到错误.

I am working on spring cloud dataflow stream app. I am able to run Spring cloud data flow server with the skipper running in Cloud Foundry . Now i am trying to run the same with the skipper running in kubernetes cluster and getting below error on deployment even though i am explicitly giving the username in the environment config in deployment.

用于Kubernetes部署的SKIPPER YML

推荐答案

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非我的用户帐户时，此问题已得到解决

This got fixed when i removed below properties from the env properties list and skipper started using the default service instead of my user account

• 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:"

• name: "SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_KUBERNETES_ACCOUNTS_K8S_FABRIC8_USERNAME" value: "" - name: "SPRING_CLOUD_SKIPPER_SERVER_PLATFORM_KUBERNETES_ACCOUNTS_K8S_FABRIC8_PASSWORD" value: ""
