【中文标题】无法使用入口点运行 docker 容器【英文标题】：Unable to run the docker container using the entrypoint 【发布时间】：2018-03-15 19:55:35 【问题描述】：

我能够成功地构建和运行这个 docker 容器，但是里面的 asp.net 核心应用程序/微服务无法运行并退出而没有给出任何错误。

这里是 docker 容器的日志。

这里是 docker 文件。

docker-compose 命令正在退出 asp.net 代码，没有任何错误代码。那么如何调试这个问题或者这个问题的可能解决方案是什么。我已将 dockerfile 中的入口点明确定义为“ENTRYPOINT [“dotnet”，“FloUserManagement.dll”]”，但它无法在容器内执行代码/微服务。

【问题讨论】：

入口点不是必须放在文件末尾吗？另外，码头工人日志在说什么？删除-d，然后发布日志。另外我假设FloUserManagement.dll 已经构建并且在您的当前目录中可用？因为你没有在 dockerfile 中构建任何东西 【参考方案1】：

@tarun lalwani，感谢您的更新。我删除了 -d --build 选项，docker 服务运行成功。

【讨论】：

以上是关于无法使用入口点运行 docker 容器的主要内容，如果未能解决你的问题，请参考以下文章

Docker - 无法通过脚本删除容器内的文件

无法使用 Spring 数据源参数运行 docker 容器

无法在 CentOS 上运行的 Docker 容器中使用 yum

无法通过 Docker 容器运行 NodeJS 微服务

VS Code 没有为在 Docker 容器中运行的 Node 应用程序打断点

由于出现此错误，无法运行 docker 容器：无法访问 jarfile app.jar
