Question

我有以下 docker-compose ：

Collecting googleapis-common-protos (from gcloud==0.17.0->pyrebase)
  Using cached

至于 mysql.yml ：

version: '2'
services:
    cryptohds:
        image: cryptohds:cryptohds-2.0.0-SNAPSHOT
        environment:
            - APP_SLEEP=10 # gives time for the database to boot before the application
            - SPRING_DATASOURCE_DRIVER_CLASS_NAME=com.mysql.jdbc.Driver
            - SPRING_DATASOURCE_URL=jdbc:mysql://cryptohds-mysql:3306/cryptohds?useUnicode=true&characterEncoding=utf8&useSSL=false
            - SPRING_DATASOURCE_USERNAME=root
            - SPRING_DATASOURCE_PASSWORD=cryptohds
    cryptohds-mysql:
        extends:
            file: mysql.yml
            service: cryptohds-mysql

当缩放加密时，它们可以很好地扩展，但它们都使用相同的 cryptohds-mysql 。我想扩展加密，每个实例都有自己的 cryptohds-mysql 。

我怎样才能做到这一点？它们应该是两个在它们之间共享网络然后单独扩展它们的服务吗？但在这种情况下，我如何使用SPRING_DATASOURCE_URL？

更新

我实际上已经构建了一个可以满足我需要的码头组合，但它并不是动态的。它专门创建了每个实例2个，我想要一个随机数。有没有其他方式动态这样做？或者只用脚本？

version: '2'
services:
    cryptohds-mysql:
        image: mysql:5.7.20
        environment:
            - MYSQL_USER=root
            - MYSQL_ROOT_PASSWORD=cryptohds
            - MYSQL_ALLOW_EMPTY_PASSWORD=yes
            - MYSQL_DATABASE=cryptohds
        ports:
            - 3306
        command: mysqld --lower_case_table_names=1 --skip-ssl --character_set_server=utf8 --explicit_defaults_for_timestamp

Answer 1

要将容器作为完全独立的组运行，我建议将它们定义为docker-compose中的单独“项目”。在群集模式中，等价物将部署单独的“堆栈”。项目名称默认为您当前的目录名称。您可以使用-p选项覆盖它，例如：

docker-compose -p cryptohds2 up

Docker撰写：扩展两种服务
