如何在 docker-compose 中定义 build-args? [英] How to define build-args in docker-compose?

问题描述

我有以下 docker-compose 文件

I have the following docker-compose file

version: '3'
services:
    node1:
            build: node1
            image: node1
            container_name: node1

    node2:
            build: node2
            image: node2
            container_name: node2

我可以构建两个图像并用一个命令启动它们

I can build both images and start them with a single command

docker-compose up -d --build

但我想在构建中使用 build-args.compose 范围之外的图像的原始构建脚本如下所示

But I would like to use build-args on the builds. The original build script of the image outside of the scope of compose looks something like this

#!/bin/sh
docker build 
--build-arg ADMIN_USERNNAME_1=weblogic 
--build-arg ADMIN_PASSWORD_1=weblogic1 
--build-arg ADMIN_NAME_1=admin 
--build-arg ...
--build-arg ... 
-t test/foo .

两个图像都将使用名称相同但值不同的构建参数.此外，由于有数十个构建参数，将它们存储在组合服务特定的构建属性文件中会很方便.这可以通过 docker-compose 实现吗?

Both images would use build-args of the same name but different value. Also, as there are dozens of build args, it would be convenient to store them in a compose service specific build-properties file. Is this possible with docker-compose?

推荐答案

您可以直接在 docker-compose 文件中指定参数:

You can specify the arguments directly in your docker-compose file:

node1:
    build: node1
        args:
            ADMIN_USERNNAME: weblogic1
            ADMIN_PASSWORD: weblogic1
            ADMIN_NAME: admin1
    image: node1
    container_name: node1

有关详细信息，请参阅官方文档.
