这里的COPY指令和Linux的copy指令用法有所区别。Linux中的copy是通过参数对目录的cp进行控制,但是这里没有使用参数。因此运用自己的规则: 如果源目标都是文件夹,那么COPY会将源目录下的所有子文件或者目录COPY到目标目录下(If <src> is a directory, the entire contents of the directory are copied, including fi...
<src>路径必须在构建的上下文内部;您不能执行COPY ../something /something,因为docker build的第一步是将上下文目录(和子目录)发送到 docker 守护进程。 If<src>is a directory, the entire contents of the directory are copied, including filesystem metadata. 如果<src>是目录,则复制目录的整个内容,包括文件...
COPY Gopkg.lock Gopkg.toml /go/src/project/ WORKDIR /go/src/project/ # Install library dependencies RUN dep ensure -vendor-only # Copy the entire project and build it #拷贝整个项目并构建 # This layer is rebuilt when a file changes in the project directory #当项目目录里有文件变化时,这一...
COPYobeys the following rules: The<src>pathmust be inside thecontextof the build; youcannotCOPY ../something /something, because the first step of adocker buildis tosend the context directory (and subdirectories) to the docker daemon. If<src>isa directory, the entire contents of the director...

COPY . /app:将当前项目目录中的所有文件复制到容器的/app目录中。 RUN pip install -r requirements.txt:安装项目所需的依赖,依赖列表通常保存在requirements.txt文件中。 ENV PYTHONPATH=/app:设置PYTHONPATH环境变量,指定Python模块的搜索路径。 CMD ["python", "script.py"]:在容器中运行python脚本文件scr...
