我正在尝试为 Mac 上的 .NET8 API 创建一个 docker 容器，以便部署到 CloudRun，这在使用 .NET6 时运行得很好，因为我们已经在生产中运行了一些大约一年。但是当我执行
docker build .-t testapi:alpine-secure-test-runtime-f Dockerfile-TestAPI

我收到以下错误： [build 7/10] RUN dotnet restore -vd \'XYZ.Test.API/XYZ.Test.API.csproj\':0.114 [/usr/share/dotnet/sdk/8.0.303/dotnet.runtimeconfig.json] 中发生 JSON 解析异常，偏移量 0（第 1 行，第 1 列）：文档为空。0.114 无效的 Runtimeconfig.json [/usr/share/dotnet/sdk/8.0.303/dotnet.runtimeconfig.json] [/usr/share/dotnet/sdk/8.0.303/dotnet.runtimeconfig.dev.json]

看起来这是预期的路径 /usr/share/dotnet/sdk/8.0.303/ 但它实际位于 /usr/local/share/dotnet/sdk/8.0.303/

基于此，我在 Mac 上运行了命令 grep -r '/usr/share/dotnet/sdk/8.0.303'，我从名为 **./.docker/scout/sbom/sha256/d42c4838eac81b78f129fac7d901a005615e9d4a0a5eb08d1898d442f36f2e6a/sbom.json ** 的 docker 文件中得到了数百个匹配项。

目前，我不确定这是否是破坏容器创建过程的原因，或者如何修复它。我期望找到一个可配置的实例，一旦正确设置，它就可以解决问题。

还尝试修复警告 FromPlatformFlagConstDisallowed，并通过在 FROM 之前添加 ARG 来存储它来完成。不幸的是，它仍然显示相同的错误。

我访问了 Rider 社区论坛、Docker 社区论坛/Git 等，寻求对我的问题的澄清，但不幸的是，我没有找到任何可以指明正确方向的东西。

使用.Net6 或使用.NET8 自动生成的项目 DockerFile 时此过程不会失败，仅在使用 alpine 时才会失败。

请指教。
