Question

运行java -jar shinyproxy-1.0.2.jar并访问我的应用后遇到此问题：

Error
Status code: 500
Message: Failed to start container: Request error: POST http://localhost:2375/containers/create: 400, body: {“message”:“invalid reference format”}
Stack Trace:
eu.openanalytics.ShinyProxyException: Failed to start container: Request error: POST

来自shinyproxy.io的帮助：https://www.shinyproxy.io/troubleshooting/#failed-to-start-container

我检查过防火墙并且已禁用。

我还检查了我的docker.service文件，所有内容都按顺序显示：

我使用的是Ubuntu 16.04。这里有什么帮助吗？

OP在这里回答。

我设法通过卸载所有以前的docker安装来解决问题，并按照Digital Ocean's guide安装Docker for Ubuntu 16.04。

完成此操作后，我重新配置了我的SelectedFooItem以包含this post的代码，以及我的Dockerfile以将application.yml行更改为docker-cmd

我当然重新调整了我的图像，因为我还需要一些其他库和外部依赖项才能工作，但从本质上讲，下载闪亮服务器文件的行是让我走的让我使用docker-cmd: ["/usr/bin/shiny-server.sh"]启动应用程序以正确启动Spring启动应用程序。

此外，为了调试在容器内运行的闪亮应用程序（当然，并非一切正常），我将java -jar shinyproxy-1.0.2.jar中的CMD行更改为Dockerfile，上一行CMD ["R", "-e", "shiny::runApp('/srv/shiny-server')"]行到docker-cmd

Docker：错误500 - 无法启动容器
