"An assembly specified in the application dependencies manifest was not found" 使用 docker

"An assembly specified in the application dependencies manifest was not found" using docker

我正在尝试使用以下 dockerfile 对 an angular aspnet core 2.2 webapi 进行 docker 化：

FROM mcr.microsoft.com/dotnet/core/sdk:2.2.105 AS build
WORKDIR /src

# Copy csproj and restore as distinct layers
COPY ["Fightplan_v1/Fightplan_v1.csproj", "Fightplan_v1/"]
COPY ["Fightplan_v1.Autogenerate/Fightplan_v1.Autogenerate.csproj", "Fightplan_v1.Autogenerate/"]
COPY ["Fightplan_v1.Autogenerate.Test/Fightplan_v1.Autogenerate.Test.csproj", "Fightplan_v1.Autogenerate.Test/"]
COPY ["Fightplan_v1.Database/Fightplan_v1.Database.csproj", "Fightplan_v1.Database/"]
COPY ["Fightplan_v1.Helpers/Fightplan_v1.Helpers.csproj", "Fightplan_v1.Helpers/"]
COPY ["Fightplan_v1.Jobs/ConvertImagestoBlob/Fightplan_v1.ConvertImagestoBlob.csproj", "Fightplan_v1.Jobs/ConvertImagestoBlob/"]
COPY ["Fightplan_v1.Models/Fightplan_v1.Models.csproj", "Fightplan_v1.Models/"]
COPY ["Fightplan_v1.Shared/Fightplan_v1.Shared.csproj", "Fightplan_v1.Shared/"]
RUN dotnet restore "Fightplan_v1/Fightplan_v1.csproj"

# Copy everything else and build
COPY . .
WORKDIR "/src/Fightplan_v1"
RUN dotnet build "Fightplan_v1.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "Fightplan_v1.csproj" -c Release -o /app

# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:2.2 AS runtime
WORKDIR /app
COPY --from=build /app .

EXPOSE 80
ENTRYPOINT ["dotnet", "Fightplan_v1.dll"]

使用的构建命令是：

docker build -f .\fp.dockerfile -t test .

构建过程顺利，但是当我尝试 运行 它时使用：

docker run -p 5100:80 -it test

我收到以下错误：

我试过：

  1. 将-r linux-x64添加到发布的末尾以定义运行时间：RUN dotnet publish "Fightplan_v1.csproj" -c Release -o /app -r linux-x64
  2. 正在将 <PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest> 添加到我的 .csproj 文件中
不幸的是，

None 上述修复有效。

由于这是一个 angular 应用程序和一个 webapi 的组合项目，我可能会遗漏一些 installations/dependencies?

您正在从错误的层复制运行时间文件

COPY --from=build /app .

尝试改成

COPY --from=publish /app .

此外，您可能需要在构建和发布步骤中分离出路径：

RUN dotnet build "Fightplan_v1.csproj" -c Release -o /app/build
RUN dotnet publish "Fightplan_v1.csproj" -c Release -o /app/publish

然后从发布文件夹运行复制时间文件

COPY --from=publish /app/publish .

编辑。 基本上，您需要将 publish 个工件复制到 运行 时间，而不是 build。构建将生成 deps.json，它将列出所有外部依赖项，并且在 运行 期间，此库使用 NuGet 缓存进行解析，如果它为空，您将看到错误。要将依赖项与项目文件一起复制，您需要 运行 publish。 所以我假设，理论上 dotnet build 可以省略，并且仅用于发现 docker build.

早期阶段的编译错误
