Docker 基于 microsoft/aspnet 的容器无法加载 Kestrel

Question

我正在尝试 asp.net 5 的各种新功能并记录下来，现在我遇到了第一个障碍。我无法在 docker 容器中获取我的代码运行，我什至没有尝试让容器监听更改，我只是想让它运行.

我的图像基于 microsoft/aspnet 并添加了代码来安装 node、npm、bower 和 grunt，这样我就可以构建容器中的应用。我知道我可能可以在将它添加到容器之前在客户端中构建它，但我想试一试。图像构建良好，但是当我启动容器时它找不到 Kestrel.

System.IO.FileNotFoundException: Could not load file or assembly 'Kestrel' or one of its dependencies. The system cannot find the file specified.

不应该 Kestrel 已经存在，因为我是基于 microsoft/aspnet 的吗？

我的 Dockerfile 的代码：https://github.com/mastoj/OneManBlog/blob/master/src/OneManBlog/Dockerfile

Answer 1

microsoft/aspnet 基础映像 (https://github.com/aspnet/aspnet-docker/blob/master/1.0.0-beta4/Dockerfile) 只为您提供运行 Kestrel 所需的最小发行版，包括 dnvm 和最新的 dnx，但不包括 Kestrel 本身。将 Kestrel NuGet 包添加到 project.json 中的依赖项并再次构建 docker 映像：

"dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-beta4",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta4",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta4",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta4",
    "Microsoft.AspNet.Hosting": "1.0.0-beta4",
    "Kestrel": "1.0.0-beta4"
}

编辑：对您的存储库进行了测试，结果成功了:)
