问题描述

当我创建一个用于部署的 docker 文件时，该应用程序通常在开发环境中工作，它因 libgdiplus 问题而失败.

The application is normally working with development environment when i create a docker file for deployment it getting failed with libgdiplus issue.

DockerFile

FROM mcr.microsoft.com/dotnet/core/aspnet:3.0 AS base
WORKDIR /app
FROM mcr.microsoft.com/dotnet/core/sdk:3.0 AS build


RUN apt-get update && apt-get install -y apt-utils
RUN apt-get install -y libfontconfig1
RUN apt-get install -y libgdiplus
RUN apt-get install -y libc6-dev 
RUN ln -s /usr/lib/libgdiplus.so/usr/lib/gdiplus.dll

# copy csproj and restore as distinct layers
WORKDIR /src
COPY HelloWorld/HelloWorld.csproj HelloWorld/
RUN dotnet restore HelloWorld/HelloWorld.csproj
COPY . .


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

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

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

即使我尝试了以下脚本来加载库，但仍然失败

RUN apt-get update  
    && apt-get install -y --allow-unauthenticated 
     libc6-dev  
    libgdiplus  
    libx11-dev  
    && rm -rf /var/lib/apt/lists/*

推荐答案

您在构建容器映像中安装 libgdiplus，但不是在最终容器映像中.您需要确保 libgdiplus 已安装在您的最终容器映像中.

You're installing libgdiplus in your build container image, but not in your final container image. You need to make sure libgdiplus is installed in your final container image.

您可以考虑像这样修改您的 Dockerfile:

You can consider amending your Dockerfile like this:

FROM mcr.microsoft.com/dotnet/core/aspnet:3.0 AS base
RUN apt-get update && apt-get install -y libgdiplus

WORKDIR /app
FROM mcr.microsoft.com/dotnet/core/sdk:3.0 AS build
[...]
