asp.net - 基于microsoft/aspnet的Docker容器无法加载Kestrel

Question

我正在尝试 asp.net 5 的所有新功能并对其进行记录，现在我遇到了第一个障碍。我无法让我的代码在 docker 容器中运行，我什至没有试图让容器监听更改，我只是想让它运行。

我的图像基于 microsoft/aspnet并添加了安装代码 node , npm , bower和 grunt所以我可以在容器中构建应用程序。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，但我想尝试一下。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，因为我基于 microsoft/aspnet ?

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

Answer 1

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

"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 repo 进行了测试，并使其工作:)
