【问题描述】:
我正在尝试将custom built SCDF2.5.1(添加 oracle 驱动程序)安装到 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 映像。现在,当我启动容器时,出现以下错误

我看到一个与这篇文章相关的线程,其中fix 被提供给 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 映像本身时在 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。仅供参考,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。
【问题讨论】:
-
您使用的 Oracle 驱动程序可能与我们提供的 Hibernate 版本不兼容。如果你可以分享捆绑 SCDF 自动配置的 Spring Boot 应用,我们可以看看。
-
嗨 Anandan,我在 Github 上创建了一个 repo。下面是位置。 custom-build:2.5.1+OracleDriver
-
您应该显示完整的服务器启动日志,因为这可能会说明更多信息。
-
Janne,在 git repo 中添加了完整的日志文件。CustomSCDF_OpenShift.log
-
您好,我在下面添加了我的答案。如果属性来自服务器配置,为什么您认为它们不会被读取?在尝试将其映射到部署时,我还在 server-config 文件中看到了一些警告。
WARNING:Config map scdf-server contains keys that are not valid environment variable names. Only config map keys with valid names will be added as environment variables.但我使用了来自 SCDF-core 项目的那个。不过,我无法准确找到这个问题。但是,如果您认为我下面的回答是有效的,请告诉我我可以将其标记为答案并关闭此线程。
