我正在尝试安装 custom built SCDF2.5.1 (添加 oracle 驱动程序)到 openshift(按照 SCDF 的 Kubectl 安装文档)。我修改了 deployment.yaml 以从 git repo 中提取我的这个自定义 SCDF docker 镜像。现在，当我启动容器时，出现以下错误

我看到了一个与这篇文章相关的线程，其中 fix提供给 spring-cloud-dataflow-server-kubernetes 和 spring-cloud-dataflow-server-kubernetes-autoconfigure 项目。但我不确定这些更改是否可用于自定义构建 2.5.1 版本。我还检查了我的 deployment.yaml 并将切换“SPRING_CLOUD_DATAFLOW_FEATURES_SCHEDULES_ENABLED”设置为 true。
在 deployment.yaml 中，我删除了数据库服务和配置，也删除了 scdf-server 配置，因为我在构建 docker 镜像本身时在 application.properties 中添加了驱动程序属性。下面是 scdf jar 中内置的 deployment.yaml 和 application.properties 文件。仅供引用，从 deployment.yaml 中删除 scdf-server 配置对失败没有影响。上述异常保持不变。还删除了船长 URI。

那么我在这里做错了什么或错过了什么？请指教。
提前致谢。
最佳答案
您很可能缺少任务平台配置server-config.yaml这是 k8s 部署文件的一部分。当您使用自己的 application.properties文件我感觉你没有使用那个 k8s 配置文件。
