这是我对.net核心和docker的第一次尝试。我不知道什么是错的。
我可以毫无问题地在终端中运行dotnet restore
/ dotnet build
/ dotnet run
。网站加载很好。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 .
会导致:
Step 5 : RUN dotnet build
---> Running in e463aff85460

我试过在没有运气的情况下更改project.json中的SQLite版本。
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"]
尝试在谷歌搜索后创建一个.dockerignore而没有任何运气:
.git
Dockerfile
.DS_Store
.gitignore
README.md
project.lock.json
我在最新的macOS上(10.12)。

尝试构建docker容器后的输出:

image microsoft / dotnet:latest不是为构建而设计的,而是仅针对运行时。
将.net核心应用程序发布到docker中的最佳方法是:
dotnet restore
dotnet publish
docker build -t your-tag
与Dockerfile类似:
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是您真正的发布路径。
如果您想在docker中构建.net核心应用程序,请使用此图像:
FROM microsoft/dotnet:onbuild
