aspnetcore docker 容器上的开发证书

Question

我是 Docker 新手，由于缺少 ssl 证书，我在 docker 中运行我的应用程序时遇到了麻烦。如何使用开发证书在非开发环境的 docker 中运行 aspnetcore 应用程序？

我有以下由 Visual Studio 生成的Dockerfile：

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY ["MyApp/MyApp.csproj", "MyApp/"]
COPY [...other libraries...]
RUN dotnet restore "MyApp/MyApp.csproj"
COPY . .
WORKDIR "/src/MyApp"
RUN dotnet build "MyApp.csproj" -c Release -o /app/build

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

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

当我使用默认设置（开发）从 Visual Studio 运行它时，它会连接 Docker 并且一切运行正常。但是，我想使用不同的 appsettings 文件 (appsettings.docker.json)，因为在 Docker 中运行时我需要一些不同的值，并且我已经在使用我的 appsettings.development.json 从 VS 进行标准运行。因此我设置了ASPNETCORE_ENVIRONMENT=Docker。这引起了我的痛苦，因为我突然收到了InvalidOperationException：

System.InvalidOperationException: Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date.

To generate a developer certificate run 'dotnet dev-certs https'. To trust the certificate (Windows and macOS only) run 'dotnet dev-certs https --trust'.

根据this 的回答，我发现当环境变量为Development 时，dotnet 会自动生成开发证书。对于不同的环境，如何解决这个问题？

我确实尝试在 Dockerfile 中使用 dotnet dev-certs https 命令，但是构建失败，说映像中没有 sdk，因此不知道该命令。

尝试添加这两行

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
# Add the line below ---------------------------------------------------
RUN dotnet dev-certs https
WORKDIR /src
COPY ["MyApp/MyApp.csproj", "MyApp/"]
COPY [...other libraries...]
RUN dotnet restore "MyApp/MyApp.csproj"
COPY . .
WORKDIR "/src/MyApp"
RUN dotnet build "MyApp.csproj" -c Release -o /app/build

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

FROM base AS final
WORKDIR /app
# Add the line below ---------------------------------------------------
COPY --from=publish /root/.dotnet/corefx/cryptography/x509stores/my/* /root/.dotnet/corefx/cryptography/x509stores/my/
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "MyApp.dll"]
