我按照Visual Studio Code的指导创建了一个ASP.NET MVC应用程序。我可以在我的本地(Windows 8)上运行它。但是当我试图将它发布到Docker时,问题就发生了。
我的dockerfile喜欢
FROM microsoft/aspnet:1.0.0-beta4
#install npm in docker image
RUN apt-get update && apt-get install -y curl
RUN curl -sL https://deb.nodesource.com/setup | bash -
RUN apt-get install -y nodejs
#install bower and grunt
RUN npm install -g bower
RUN npm install -g grunt-bower-cli
RUN npm install -g grunt
RUN npm install -g grunt-cli
RUN npm install -g grunt-bower-task
COPY project.json /app/
WORKDIR /app
RUN ["dnu", "restore"]
COPY . /app
CMD ["cd", "/app/"]
CMD ["npm", "install"]
CMD ["bower", "install"]
EXPOSE 5001
ENTRYPOINT ["dnx", "kestrel"]
然后我试着建立它
docker build -t thangchung/webdemo .
和
docker run -i -p 8080:5001 -t thangchung/webdemo
当我运行上面的代码时,它总是抛出异常
System.InvalidOperationException: Unable to resolve project 'kestrel' from /app/kestrel

有人能让我知道为什么我无法在Docker上运行它吗?
欢迎任何建议。感谢。

您是否使用了来自aspnet-docker github project的正确Docker镜像?

根据文章 - 你错过了
RUN ["kpm", "restore"]
Dockerfile
中的。

使用从k到dnx的更新,您现在必须为包含project.json的目录提供路径参数。那么过去是什么
k kestrel
变为
dnx . kestrel
