我遇到问题让我的MySQL容器从Docker Compose运行一些初始化脚本(创建一些数据库)。根据Docker Hub上的文档,我将.sql
文件挂载到/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
./scripts/db
的内容只是1个文件init-databases.sql
:
CREATE DATABASE myservice;
启动后,MySQL正在运行,但未创建数据库。服务容器也成功链接到MySQL容器。抨击MySQL容器; init脚本已成功安装在正确的位置。
有人能看到一些明显的问题吗?

检查这是否是停泊者撰写问题(例如重定向到issue 115的issue 2266)
我不认为错误与构建有关,它很可能是卷 撰写保留卷以便您不会丢失数据(这将在下一版本中更好地记录)。
要删除这些卷,请运行
docker-compose rm -vf
。下次你使用docker-compose时,它应该从新的空卷开始。
根据hub.docker.com/mysql,还要检查这是否是同步问题:
如果容器启动时没有初始化数据库,则将创建一个默认数据库。虽然这是预期的行为,但这意味着在初始化完成之前它不会接受传入的连接。 使用自动化工具时可能会出现问题,例如docker-compose,它会同时启动多个容器。
