MySQL容器无法在Docker Compose中运行初始化脚本

我在让我的MySQL容器运行来自Docker Compose的一些初始化脚本（创建一些数据库）时遇到问题。根据Docker

Hub上的文档，我将.sql文件挂载在其中，/docker-entrypoint-initdb.d但无济于事。

我的撰写文件如下：

version: '2'
services:
  database:
    image: mysql
    ports:
      - "3307:3306"
    environment:
      MYSQL_ROOT_PASSWORD: root
    volumes:
      - ./scripts/db:/docker-entrypoint-initdb.d
  myservice:
    image: company/myservice
    expose:
      - "10001"
    depends_on:
      - database
    links:
      - database
    environment:
      SERVICE_PORT: 10001
      DATABASE_URL: jdbc:mysql://database:3306/myservice?autoReconnect=true&useSSL=false&characterEncoding=UTF-8

的内容./scripts/db只有1个文件init-databases.sql：

CREATE DATABASE myservice;

一旦启动，MySQL正在运行，但未创建数据库。服务容器还成功链接到MySQL容器。扑向MySQL容器；初始化脚本已成功安装在正确的位置。

有人可以在这里看到一些明显的问题吗？

回答：

检查这是否是docker-compose问题（例如问题115，重定向到问题2266）

我认为该错误与构建无关，它很可能是卷。

Compose会保留卷，这样您就不会丢失数据（在下一发行版中将有更好的记录）。

要删除这些卷，请运行docker-compose rm -vf。下次您进行docker-compose时，它应该从新的空卷开始。

根据hub.docker.com/mysql，还检查这是否不是同步问题：

如果在容器启动时没有初始化数据库，则将创建一个默认数据库。尽管这是预期的行为，但这意味着在初始化完成之前它将不接受传入的连接。

。
