如何使用docker-compose指定图像名称

Question

这是我的docker-compose文件

我使用docker-compose build命令构建了图像。

如何构建命名图像？因为我有太多的非图像

Answer 1

我不知道为图像设置自定义名称的方法，总是将图像标记为project_service:latest。我们使用的模式是类似于此的启动脚本：

#!/bin/sh
docker-compose kill
docker-compose rm --force -v
docker rmi project_service:latest    # prevents buildup of untagged images
docker-compose build
docker-compose up -d

如果您不想使用启动脚本，另一种解决方案是保持这个方便并经常运行：

docker rmi $(docker images -q -f dangling=true)
