如何将环境变量传递给docker-compose up [英] How to pass environment variable to docker-compose up

问题描述

我正在尝试运行一个容器。我已经将映像上传到私有Docker注册表。我想编写一个撰写文件来下载和部署映像。但是我想通过docker-compose run命令将TAG名称作为变量传递。我的撰写文件如下所示。如何作为docker-compose up命令的一部分传递KB_DB_TAG_VERSION的值？

I am trying to run a container. I already have the image uploaded to private Docker registry. I want to write a compose file to download and deploy the image. But I want to pass the TAG name as a variable from the docker-compose run command.My compose file looks like below. How can I pass the value for KB_DB_TAG_VERSION as part of docker-compose up command?

version: '3'
services:
   db:
    #build: k-db
    user: "1000:50"
    volumes:
      - /data/mysql:/var/lib/mysql
    container_name: k-db
    environment:
      - MYSQL_ALLOW_EMPTY_PASSWORD=yes
    image:  XX:$KB_DB_TAG_VERSION
    image: k-db
    ports:
      - "3307:3306"

推荐答案

两个选项：

1. 创建。env文件，已在另一个答案中已建议。



2. 将 KEY = VALUE 对添加到 docker-compose 命令，例如：

1. Create the .env file as already suggested in another answer.

2. Prepend KEY=VALUE pair(s) to your docker-compose command, e.g:

KB_DB_TAG_VERSION=kb-1.3.20-v1.0.0 docker-compose up

早些时候将其导出na脚本也应正常工作，例如：

Exporting it earlier in a script should also work, e.g.:

export KB_DB_TAG_VERSION=kb-1.3.20-v1.0.0
docker-compose up
