docker run：无法执行，因为找不到指定的命令或文件

Question

我为 .net 核心控制台应用程序制作了一个 docker 文件：

FROM mcr.microsoft.com/dotnet/core/sdk:3.1
LABEL author="some name"
LABEL description="some description"
ENTRYPOINT [ "dotnet", "L1_1_Console.dll" ]

并从中创建了一个名为“labo1_1_console_image”的图像

当我尝试使用此命令运行此映像时：

docker run --rm -it labo1_1_console_image

我收到此错误：

Could not execute because the specified command or file was not found.
Possible reasons for this include:
  * You misspelled a built-in dotnet command.
  * You intended to execute a .NET Core program, but dotnet-L1_1_Console.dll does not exist.
  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

我认为问题是第二个问题（我不确定），但我不知道如何解决这个问题，我的 L1_1_Console.dll 文件分别位于 docker 文件位置 /bin/Release/netcoreapp3.1（我也有发布这里的文件夹与相同的文件）

更新：

我将 docker 文件更改为：

FROM mcr.microsoft.com/dotnet/core/sdk:3.1
LABEL author="somename"
LABEL description=" some description"
ADD bin/Release/netcoreapp3.1/publish/L1_1_Console.dll L1_1_Console.dll
ADD bin/Release/netcoreapp3.1/publish/L1_1_Console.runtimeconfig.json L1_1_Console.runtimeconfig.json
ENTRYPOINT [ "dotnet", "L1_1_Console.dll" ]

Answer 1

将您的 Dockerfile 更改为

FROM mcr.microsoft.com/dotnet/core/sdk:3.1
LABEL author="some name"
LABEL description="some description"
ADD bin/Release/netcoreapp3.1/L1_1_Console.dll L1_1_Console.dll
ENTRYPOINT [ "dotnet", "L1_1_Console.dll" ]

入口点只能看到你的docker镜像中的文件（除非你挂载了一个外部卷），所以你需要手动将你的dll文件添加到镜像中才能运行它。
