我正在尝试为已经编译的VS项目的可执行文件中的第一次构建一个docker镜像。我不希望docker构建我的项目(哦,没有给出我已经存在的问题)。因此,我在我的应用程序源文件(和已编译的二进制文件)所在的文件夹中有以下Dockerfile:
地点:d:\MyApp
Dockerfile内容:
FROM microsoft/windowsservercore
COPY bin /app
ENTRYPOINT ["C:\\app\\x86\\Debug\\MyApp.exe"]
MyApp文件夹的内容:
MyApp\
MyApp\bin
MyApp\bin\x64
MyApp\bin\x64\Release
MyApp\bin\x64\Debug
MyApp\bin\x64\Release\* (lots of binaries)
MyApp\bin\x64\Debug\* (lots of binaries)
...
MyApp\Dockerfile
命令窗口:
d:\MyApp> docker image build .
Sending build context to Docker daemon 3.584kB
Step 1/3 : FROM microsoft/windowsservercore ---> 4dba31379dad
Step 2/3 : COPY bin /app COPY failed: CreateFile \\?\C:\ProgramData\Docker\tmp\docker-builder196938557\bin: The system cannot find the file specified.
如果我将COPY行更改为COPY ./bin/*.* /app/
:
Sending build context to Docker daemon 3.584kB
Step 1/3 : FROM microsoft/windowsservercore
---> 4dba31379dad
Step 2/3 : COPY ./bin/*.* /app/
COPY failed: no source files were specified
答案 0 :(得分:2)
不知怎的,我有一个带有“*”的“.dockerignore”。删除该行后,一切似乎都没问题。
