构建 docker 镜像时包含文件的默认位置是什么? [英] What is the default location for included files when building a docker image?

问题描述

derrend@laptop ~/topdir $ docker version
Client version: 1.7.1
Client API version: 1.19
Go version (client): go1.4.2
Git commit (client): 786b29d
OS/Arch (client): linux/amd64
Server version: 1.7.1
Server API version: 1.19
Go version (server): go1.4.2
Git commit (server): 786b29d
OS/Arch (server): linux/amd64

<小时>

derrend@laptop ~/topdir $ pwd; ls *
$HOME/topdir
Dockerfile

afolder:
afile

据我所知，当我执行 docker build 时，afolder 及其内容将包含在我的 docker 映像中，但如果我不这样做，它们将被放置在哪里在 Dockerfile?

As I understand it, when I execute a docker build the afolder and its contents will be included inside my docker image but where will they be placed if I do not designate a location in the Dockerfile?

推荐答案

那些文件不是构建(最终结果)图像的一部分.

Those files are not part of the built (end-result) image.

它们是传递给守护进程的构建上下文的一部分在构建过程中，由 Dockerfile 指令使用，例如 <代码>添加或COPY 或 RUN.

They are part of the build context passed to the daemon during the build process, to be used by Dockerfile directives like ADD or COPY or RUN.

构建的上下文是位于指定 PATH 或 URL

A build’s context is the files located in the specified PATH or URL

例如，运行此命令以使用分支容器中名为 docker 的目录:

For example, run this command to use a directory called docker in the branch container:

$ docker build https://github.com/docker/rootfs.git#container:docker

这由Context<管理/code> 和 ModifiableContext.
