DotNet构buildCLI在terminal中工作，但不在Docker构build中

这是我第一次尝试.net核心和docker。 我不知道什么是错的。

我可以在terminal运行dotnet restore / dotnet build / dotnet run ，没有任何问题。 该网站加载得很好。 所以我想给docker一个尝试（最终在云中的VM上运行）。

我运行docker build -t latest . 这导致：

 Step 5 : RUN dotnet build ---> Running in e463aff85460 Project app (.NETCoreApp,Version=v1.0) will be compiled because project is not safe for incremental compilation. Use --build-profile flag for more information. Compiling app for .NETCoreApp,Version=v1.0 /app/project.json(32,58): error NU1001: The dependency Microsoft.EntityFrameworkCore.Sqlite >= 1.0.1 could not be resolved. Compilation failed. 0 Warning(s) 1 Error(s) Time elapsed 00:00:00.0174732 The command 'dotnet build' returned a non-zero code: 1 

我已经尝试更改project.json中的SQLite版本没有任何运气。

NuGet回购：使用的饲料：

 https://www.myget.org/F/aspnetcirelease/api/v3/index.json https://api.nuget.org/v3/index.json dotnet --version 1.0.0-preview3-003786 

没有编辑到dockerfile：

 FROM microsoft/dotnet:latest COPY . /app WORKDIR /app RUN ["dotnet", "restore"] RUN ["dotnet", "build"] EXPOSE 5000/tcp CMD ["dotnet", "run", "--server.urls", "http://*:5000"] 

尝试创build一个.dockerignore谷歌search后没有任何运气：

 .git Dockerfile .DS_Store .gitignore README.md project.lock.json 

我在最新的macOS（10.12）。

的package.json：

 { "dependencies": { "Microsoft.NETCore.App": { "version": "1.0.1", "type": "platform" }, "Microsoft.AspNetCore.Diagnostics": "1.0.0", "Microsoft.AspNetCore.Mvc": "1.0.1", "Microsoft.AspNetCore.Razor.Tools": { "version": "1.0.0-preview2-final", "type": "build" }, "Microsoft.AspNetCore.Routing": "1.0.1", "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0", "Microsoft.AspNetCore.Server.Kestrel": "1.0.1", "Microsoft.AspNetCore.StaticFiles": "1.0.0", "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0", "Microsoft.Extensions.Configuration.Json": "1.0.0", "Microsoft.Extensions.Configuration.CommandLine": "1.0.0", "Microsoft.Extensions.Logging": "1.0.0", "Microsoft.Extensions.Logging.Console": "1.0.0", "Microsoft.Extensions.Logging.Debug": "1.0.0", "Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0", "Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0", "Microsoft.EntityFrameworkCore": "1.0.1", "Microsoft.EntityFrameworkCore.Design": { "version": "1.0.0-preview2-final", "type": "build" }, "Microsoft.EntityFrameworkCore.Relational": "1.0.1", "Microsoft.EntityFrameworkCore.SQLite": "1.0.1", "Microsoft.EntityFrameworkCore.Sqlite.Design": "1.0.1" }, "tools": { "BundlerMinifier.Core": "2.0.238", "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final", "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final", "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final" }, "frameworks": { "netcoreapp1.0": { "imports": [ "dotnet5.6", "portable-net45+win8" ] } }, "buildOptions": { "emitEntryPoint": true, "preserveCompilationContext": true }, "runtimeOptions": { "configProperties": { "System.GC.Server": true } }, "publishOptions": { "include": [ "wwwroot", "**/*.cshtml", "appsettings.json", "web.config" ] }, "scripts": { "precompile": [ "dotnet bundle" ], "prepublish": [ "bower install" ], "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ] }, "tooling": { "defaultNamespace": "MyFirstApp" } } 

在尝试构builddocker容器之后输出：

 Sending build context to Docker daemon 26.39 MB Step 1 : FROM microsoft/dotnet:latest ---> 96d122fe36cb Step 2 : WORKDIR /root ---> Using cache ---> 0c5317108a5b Step 3 : COPY bin/Debug/netcoreapp1.0/publish/ /root/ ---> Using cache ---> d79700fa6c36 Step 4 : ENTRYPOINT dotnet /root/MyProject.dll ---> Using cache ---> a99f30826ddd Successfully built a99f30826ddd

图像microsoft / dotnet：最新不是为构build而devise的，而仅仅是为了运行时。

将.net核心应用程序发布到Docker中的最佳方式是：

1. dotnet restore
2. dotnet publish

3. docker docker build -t your-tag与Dockerfile像：

    FROM microsoft/dotnet:latest WORKDIR /root COPY bin/Debug/netcoreapp1.0/publish/ /root/ ENTRYPOINT dotnet /root/[your-project-name].dll 

   其中bin / Debug / netcoreapp1.0 / publish是您真正的发布path。

如果你想在Docker中构build.net核心应用程序，请使用以下图像：

 FROM microsoft/dotnet:onbuild
