How to build in docker Leave feedback
To build an web API which is using GroupDocs.Conversion for .NET in docker container use this sample Docker file:
FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443
RUN apt-get update && apt-get install -y ffmpeg libgdiplus
RUN sed -i'.bak' 's/$/ contrib/' /etc/apt/sources.list
RUN apt-get update; apt-get install -y ttf-mscorefonts-installer fontconfig
RUN fc-cache -f -v
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY ["YourApi/YourApi.csproj", "TestApi/"]
RUN dotnet restore "YourApi/YourApi.csproj"
COPY . .
WORKDIR "/src/YourApi"
RUN dotnet build "YourApi.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "YourApi.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "YourApi.dll"]
As you can see the process is the same as building a regular web API project in docker. The main difference is the installation of needed libraries which allows GroupDocs.Conversion for .NET to work properly in a docker container:
RUN apt-get update && apt-get install -y ffmpeg libgdiplus
RUN sed -i'.bak' 's/$/ contrib/' /etc/apt/sources.list
RUN apt-get update; apt-get install -y ttf-mscorefonts-installer fontconfig
RUN fc-cache -f -v
Also please do not forget to add runtimeconfig.template.json file next to your project file with the following content:
{
"configProperties": {
"System.Drawing.EnableUnixSupport": true
}
}
This will prevent exception “The type initializer for gdip throws exception”. To learn more about this read here.
