我正在 Kubernetes 集群环境中设置 Spring Cloud Dataflow。我只在 Kubernetes 部署中遇到了这个问题。仅供参考，我正在使用没有船长的服务器 2.7.0 ( https://dataflow.spring.io/docs/2.7.0.SNAPSHOT/recipes/batch/batch-only-mode/ )。当我们在本地和本地 docker 内部部署它时，它运行得非常好。但是，当我们将它部署到 Kubernetes 时，我们可以从私有 ACR 中拉取示例数据或 Docker 映像，但是当我们尝试启动它（甚至是示例数据）时，我们得到了这个错误：

java.lang.NullPointerException: null

我也尝试从 pod 内部使用 shell - 同样的问题，nullPointerException。

你知道如何减轻这种情况吗？谢谢你。
