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。
.sql
/docker-entrypoint-initdb.d
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:
./scripts/db
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?

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。 这在使用自动化工具(例如docker-compose)时可能会引起问题,该工具会同时启动多个容器 。
