如何在Dockerfile中设置图像名称？ [英] How to set image name in Dockerfile?

问题描述

您可以在构建自定义图像时设置图像名称，如下所示：

You can set image name when building a custom image, like this:

docker build -t dude/man:v2 . # Will be named dude/man:v2

有没有办法定义图像的名称Dockerfile，所以我不必在 docker build 命令中提到它。

Is there a way to define the name of the image in Dockerfile, so I don't have to mention it in the docker build command?

推荐答案

Dockerfile中不支持标记图像。这需要在你的构建命令中完成。作为解决方法，您可以使用docker-compose.yml进行构建，该docker-compose.yml标识目标映像名称，然后运行 docker-compose build 。一个示例docker-compose.yml看起来像

Tagging of the image isn't supported inside the Dockerfile. This needs to be done in your build command. As a workaround, you can do the build with a docker-compose.yml that identifies the target image name and then run a docker-compose build. A sample docker-compose.yml would look like

version: '2'

services:
  man:
    build: .
    image: dude/man:v2
