如何用docker-compose标记docker图像

小开

原来的答案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。在调用docker-compose之后，你总是可以让一些脚本调用docker tag <image> <tag>。

现在有一个如上所述的选项或在这里

build: ./dir
image: webapp:tag

最佳答案

文档/工具似乎已经更新，现在可以将image标记添加到脚本中。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:
...

如果你指定了image和build，那么Compose用image中指定的webapp和可选标签来命名构建的图像:

build: ./dir
image: webapp:tag

这将导致一个名为webapp并标记为tag的图像，从./dir构建。

你可以试试:

services:
nameis:
container_name: hi_my
build: .
image: hi_my_nameis:v1.0.0

如果你已经构建了你的映像，你可以通过使用docker tag命令re-tag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

我想补充一点，您还可以通过环境变量或.env文件管理标记版本。

https://docs.docker.com/compose/environment-variables/#the-env-file

export TAG=1.11

例子:

version: '3.3'
services:


baggins.api.rest:
image: my.image.name:${TAG}
build:
context: ../..
dockerfile: app/Docker/Dockerfile.release
ports:
...

docker-compose config来验证

在我的ci管道中，我的第一个构建被标记为用于运行测试的丢弃值。然后，我将标记更改为latest并重新构建(几乎是即时的，因为它都是缓存的)，然后推到注册表。

它为我工作: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输出，如下所示:

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

上面控制台输出spring-postgres:1.0和spring-postgres:latest
