Docker API应用程序，在 ASP.Net 从Visual Studio Only成功构建，而不是从git-bas

Question

来自 IDE 的 Docker 构建命令：

12>docker build -f "D:sampleprojectSrcServicesExampleExample.APIDockerfile" --force-rm -t exampleapi:dev --target base  --label "com.microsoft.created-by=visual-studio" --label "com.microsoft.visual-studio.project-name=Example.API" "D:sampleproject"

来自 IDE 的 Docker 运行命令：

12>docker run -dt -v "C:Usersjohndvsdbgvs2017u5:/remote_debugger:rw" -v "D:sampleprojectSrcServicesExampleExample.API:/app" -v "D:sampleproject:/src/" -v "C:UsersjohndAppDataRoamingMicrosoftUserSecrets:/root/.microsoft/usersecrets:ro" -v "C:UsersjohndAppDataRoamingASP.NETHttps:/root/.aspnet/https:ro" -v "C:Usersjohnd.nugetpackages:/root/.nuget/fallbackpackages" -e "DOTNET_USE_POLLING_FILE_WATCHER=1" -e "ASPNETCORE_LOGGING__CONSOLE__DISABLECOLORS=true" -e "ASPNETCORE_ENVIRONMENT=Development" -e "ASPNETCORE_URLS=https://+:443;http://+:80" -e "NUGET_PACKAGES=/root/.nuget/fallbackpackages" -e "NUGET_FALLBACK_PACKAGES=/root/.nuget/fallbackpackages" -P --name Example.API --entrypoint tail exampleapi:dev -f /dev/null

从命令提示符生成和运行，使容器保持运行状态。终结点不可访问。例如，curlhttp://localhost:32823/swagger/index.html从服务器返回空回复。

docker build -f dockerfile-example --force-rm -t contentocr.azurecr.io/exampleapi:lore --label "com.content.created-by=git-bash" .

docker run -dt  -v "C:Usersjohnd.nugetpackages:/root/.nuget/fallbackpackages" -e "DOTNET_USE_POLLING_FILE_WATCHER=1" -e "ASPNETCORE_LOGGING__CONSOLE__DISABLECOLORS=true" -e "ASPNETCORE_ENVIRONMENT=Development" -e "ASPNETCORE_URLS=https://+:443;http://+:80" -e "NUGET_PACKAGES=/root/.nuget/fallbackpackages" -e "NUGET_FALLBACK_PACKAGES=/root/.nuget/fallbackpackages" -P --name Example.API --entrypoint tail contentocr.azurecr.io/exampleapi:lore -f /dev/null

从容器内部，curl http://localhost:80/swagger/index.html返回连接被拒绝错误消息文本。

如何从git-bash/power/cmdshell 构建和执行容器？

对 docker 文件进行更新以包含 Visual Studio 卷装载可解决此问题，如下所示： 第 #Volume 节挂载显式复制 --
