具有相同图像的多个码头集装箱

Question

我正试图用我现有的Magento项目创建多个容器。

任务1)通过跟踪标记/码头-magento. ，成功地将现有的项目转移到了Docker，一切都像预期的那样工作得很好。但这只适用于将单个Magento实例迁移到Docker

任务# 2) 我试图以类似的方式在Docker上创建同一个现有Magento项目的多个实例

我尝试用不同的--project-name创建两个不同的YML(以区分容器)。遵循与任务# 1相同的步骤，并在第二个YML中更新外部端口。但不幸的是，我现在无法运行任何一个集装箱。不起作用！

当我试图访问第一个Magento容器(例如https://example.com:444/ )时，它在system.log中添加了错误，奇怪的是，同样的错误被记录在我的第二个码头容器的system.log中

我怀疑卷在我的例子中会产生问题(因为卷路径在两个YML中是相同的)，但是我无法在这里找到确切的问题。在下面添加两个YMLs

Answer 1

问题已经解决了。请遵照以下指示：

创建文件docker-compose-instance1.yml

version: '3'

services:
  magento:
    image: folio3ecommerce/magento-php-apache:2.4.5
    restart: on-failure
    ports:
      - "${APP_PORT}:80"
    env_file: env/phpfpm.env
    links:
      - db
      - redis
      - elasticsearch
    depends_on:
      - db
    networks:
      - customNetwork
    
  db:
    image: mariadb:10.4
    restart: on-failure
    command: --max_allowed_packet=256M
    ports:
      - "${DB_PORT}:3306"
    env_file: env/db.env
    volumes:
      - dbdata:/var/lib/mysql
    networks:
      - customNetwork

  redis:
    image: redis:5.0-alpine
    restart: on-failure
    ports:
      - "${REDIS_PORT}:6379"
    networks:

执行以下命令，通过上述YML文件为instance1创建容器

docker-compose -f docker-compose-instance1.yml -p "instance1" up -d --build

类似地，您可以使用docker-复合-instance2.yml、docker-复合-instance3.yml等创建多个实例。

您可以使用来自码头集线器https://hub.docker.com/r/folio3ecommerce/magento-php-apache/tags的以下图像

此映像为Magento实例提供了示例数据(v2.4.3、v2.4.4、v2.4.5)

我希望这能帮到你!

Answer 2

我认为看一些容易理解的例子可以给你最好的印象。

您想要做的是完全有效的，图像应该是您需要运行的任何东西，而不需要配置。

要生成配置，您可以：

( a)容积安装

在容器启动过程中使用卷并挂载文件，运行-v my.ini:/etc/mysql/my.ini percona (与docker -组合类似)

( b)基于入口点的配置(生成)

( c)衍生图像

可能是为了“完整性”，即映像派生策略，因此您有一个名为"myapp“的基本映像，而对于安装X，则创建了一个新映像。

从我的应用程序

复制my.ini /etc/mysql/my.ini 复制application.yml /var/app/config/application.yml
