docker生成dotnet core镜像

使用docker生成dotnet core项目镜像。需要编写Dockerfile文件。编写方法有两种，如下：

第一种：将发布成功的项目，直接生成镜像。

FROM microsoft/dotnet:2.2-aspnetcore-runtime

WORKDIR /app
EXPOSE 5000

COPY bin/Debug/netcoreapp2.2/publish/ app/

ENV ASPNETCORE_URLS http://*:5000

ENTRYPOINT ["dotnet", "app/WebApplication1.dll"]

第二种：发布源码，自动build，publish

FROM microsoft/dotnet:2.2-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 5000

FROM microsoft/dotnet:2.2-sdk AS build
WORKDIR /src

COPY . .

RUN dotnet restore "WebApplication1.csproj" --configfile NuGet.Config

WORKDIR "/src/"
RUN dotnet build "WebApplication1.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "WebApplication1.csproj" -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .

ENV ASPNETCORE_URLS http://*:5000

ENTRYPOINT ["dotnet", "WebApplication1.dll"]

NuGet.Config文件内容

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://nuget.cdn.azure.cn/v3/index.json" protocolVersion="3" />
  </packageSources>
</configuration>
