我有以下项目结构

我在 bin directory 中有一个目录，名为 app.publish.我的 Dockerfile 如下

And I have one directory in bin directory that name is app.publish. And my Dockerfile is like below

#Depending on the operating system of the host machines(s) that will build or run the containers, the image specified in the FROM statement may need to be changed. #For more information, please see aka.ms/containercompat FROM mcr.microsoft/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019 ARG source WORKDIR /inetpub/wwwroot COPY bin/app.publish .

在我运行以下命令以从此 docker 文件构建图像后

After I run below command to build image from this docker file

docker build -t soroshsabz/testcoreservice .

我得到以下错误

[+] Building 15.1s (7/7) FINISHED => [internal] load build definition from Dockerfile 0.1s => => transferring dockerfile: 414B 0.0s => [internal] load .dockerignore 0.1s => => transferring context: 34B 0.0s => [internal] load metadata for mcr.microsoft/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019 14.9s => [1/3] FROM mcr.microsoft/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019@sha256:e1475e80eb3cbdfd81 0.1s => => resolve mcr.microsoft/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019@sha256:e1475e80eb3cbdfd81 0.1s => [internal] load build context 0.1s => => transferring context: 2B 0.0s => CACHED [2/3] WORKDIR /inetpub/wwwroot 0.0s => ERROR [3/3] COPY bin/app.publish . 0.0s ------ > [3/3] COPY bin/app.publish .: ------ failed to compute cache key: "/bin/app.publish" not found: not found

我的问题是为什么我会收到这个错误?以及如何解决?

我在 Windows 10 20H2 19042.964

---更新:

我看到 docker - 无法计算缓存键:未找到 - 在 Visual Studio 中运行良好 和 一些内部链接但没有找到任何有用的东西.

I see docker - failed to compute cache key: not found - runs fine in visual studio and some internal links but does not found any useful things.

我正在解决我的问题并发现了一些相同的问题，例如 Dockerfile 无法复制指定的本地目录 &文件 或 Windows Docker Dockerfile复制文件夹内的文件

I am binging my problem and find some same problem like Dockerfile can’t copy specified local directory & file or Windows Docker Dockerfile COPY file inside folder

谢谢

推荐答案

感谢 BMitch，我发现了我的问题，问题是 dockerignore 文件包含一些必须与 COPY 文件名不匹配的模式.我的问题是 dockerignore 文件中的模式与 bin/app.publish 错误匹配.为了解决我的问题，我只是更改了 dockerignore 中的模式.

Thanks to BMitch, I found my problem, the problem is dockerignore file contains some pattern that must be not match with COPY files name. My problem is patterns inside dockerignore file is match wrongly with bin/app.publish. to resolve my problem I just change the pattern in dockerignore.

再次感谢 BMitch
