c# - 如何解决多个依赖 Web 应用程序时的依赖问题？

Question

如何解决恢复依赖项 docker build 时未找到的问题？我得到了这个问题。我的文件结构如下所示。

请关注我的 Dockerfile:

[Solution] 'xxxxx' (3 Projects)  |   +-- [xxxxx.Web]  |    |  |    +--- xxxxx.Web.csproj (This project holds the Docker file)  |  +-- [xxxxx.xxxxserver]  |    |  |    +--- xxxxx.xxxxserver.csproj  |  +-- [xxxxx.xxxxApi.Client]       |       +--- xxxxx.xxxxApi.Client.csproj 1. xxxxx.Web.csproj -> API 2. xxxxx.xxxxserver/xxxxx.xxxxserver.csproj -> IdentityServer 3. xxxxx.xxxxApi.Client/xxxxx.xxxxApi.Client.csproj -> xxxxApi.Client

Dockerfile:

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src
COPY ["xxxxx.Web.csproj", "./"]

COPY ["common.props", "./"]

RUN dotnet restore "xxxxx.Web.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "xxxxx.Web.csproj" -c Release -o /app/build

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

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "xxxxx.Web.dll"]

common.props:

<Project>
  <PropertyGroup>
    <LangVersion>latest</LangVersion>
    <Version>1.0.0</Version>
    <NoWarn>$(NoWarn);CS1591;CS0436</NoWarn>
    <AbpProjectType>app</AbpProjectType>
  </PropertyGroup>
</Project>

在我看来，您复制文件的路径错误。并且您还需要复制 * .sln 文件。首先检查路径。

根据问题的描述，在我看来，将 Dockerfile 做成这样会更正确:

首先，将 Dockerfile 与 sln 文件齐平。

试试这个

COPY *.sln .
COPY xxxxx.Web/*.csproj ./xxxxx.Web/
COPY xxxxx.xxxserver/*.csproj ./xxxxx.xxxserver/
COPY xxxxx.xxxxApi.Client/*.csproj ./xxxxx.xxxxApi.Client/

RUN dotnet restore

COPY . .

WORKDIR /app/xxxxx.Web
RUN dotnet publish -c release -o /app --no-restore

更新:如果您没有 *.sln 文件，只需将 WORKDIR 更改为您的启动项目，如下所示:

COPY xxxxx.Web/*.csproj ./xxxxx.Web/
COPY xxxxx.xxxserver/*.csproj ./xxxxx.xxxserver/
COPY xxxxx.xxxxApi.Client/*.csproj ./xxxxx.xxxxApi.Client/

WORKDIR /app/xxxxx.Web

RUN dotnet restore
