原答案15年11月20日:

截至今天，没有特定标记的选项。Docker compose只是发挥它的魔力，像你看到的那样分配一个标签。在你调用docker-compose之后，你总是可以有一些脚本调用docker tag <image> <tag>。

现在有一个如上所述的选项

build: ./dir
image: webapp:tag

看起来docs/tool已经更新了，你现在可以把image标签添加到你的脚本中了。这对我来说很成功。

例子:

version: '2'
services:

  baggins.api.rest:
    image: my.image.name:rc2
    build:
      context: ../..
      dockerfile: app/Docker/Dockerfile.release
    ports:
      ...

https://docs.docker.com/compose/compose-file/#build

根据官方文件:https://docs.docker.com/compose/environment-variables/set-environment-variables/

您可以从.env文件中设置环境变量

$ cat .env
TAG=v1.5

然后，您可以检索它并将其用作图像的标记。

$ cat docker-compose.yml
services:
  web:
    image: "webapp:${TAG}"

你可以通过命令docker compose convert来验证

$ docker compose convert

services:
  web:
    image: 'webapp:v1.5'

它适合我:https://docs.docker.com/build/customize/bake/compose-file/#specification

services:
  backend:
    build:
      context: ./backend
      dockerfile: Dockerfile
      tags:
        - spring-postgres:1.0
        - spring-postgres:latest
    ports:
      - 8080:8080

然后运行docker compose build——no-cache output，如下所示:

Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them

以上控制台输出spring-postgres:1.0和spring-postgres:最新

如果你已经构建了你的映像，你可以使用docker tag命令重新标记它:

docker tag imagename imagename:v1.0

docker tag imagename:v1.0 imagename:v1.1

如果你有多个标签附加到你的存储库，如果你想删除其中一个，你可以使用docker rmi命令:

$ docker rmi imagename:v1.0
Untagged imagename:v1.0
