java -jar shinyproxy-1.0.2.jar运行并访问我的应用程序后遇到此问题:

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

我检查了防火墙,它被禁用了。

我还检查了我的 docker.service 文件,一切似乎都井井有条:

我正在使用 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 安装解决了这个问题,并按照Digital Ocean 的指南为 Ubuntu 16.04 安装 Docker。

完成此操作后,我重新配置我Dockerfile以包含这篇文章中的代码,并将我的行application.yml更改为docker-cmddocker-cmd: ["/usr/bin/shiny-server.sh"]

当然,我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使其工作,但本质上,下载闪亮服务器文件的行是让我开始并让我启动应用程序的行以java -jar shinyproxy-1.0.2.jar正确启动 Spring Boot 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toCMD中的行和前一行更改为DockerfileCMD ["R", "-e", "shiny::runApp('/srv/shiny-server')"]docker-cmddocker-cmd: ["R", "-e", "shiny::runApp('/srv/shiny-server/')"]
