我试图让我的 docker db 容器在创建时自动使用数据集填充数据库。根据mariadb 文档,卷中有一个docker-entrypoint-initdb.d文件夹可用于此目的。

我将docker-compose.yml文件设置为镜像在 StackOverflow 上找到的示例,但仍然无法执行我的 SQL 脚本。以下是我docker-compose.yml文件的相关部分:

version: '3.6'
services:

  db:
    image: mariadb:10.5.4-focal
    container_name: db
    volumes:
      - ./cms/conf/mysql/data/:/var/lib/mysql/:rw
      - ./cms/sql/:/docker-entrypoint-initdb.d/:ro
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_USER=root
      - MYSQL_PASSWORD=password
      - MYSQL_DATABASE=wordpress
    restart: always

  adminer:
    image: adminer:4.7.7-standalone
    container_name: adminer
    links:
      - db
    ports:
      - 8080:8080
    restart: always

在该文件旁边docker-compose.yml,我有一个cms/sql/init.sql包含以下内容的文件:

CREATE DATABASE /*!32312 IF NOT EXISTS*/ `test` /*!40100 DEFAULT CHARACTER SET utf8mb4 */;
USE `test`;

在每次测试迭代之前,我都会清理所有旧的/缓存的 Docker 内容:

  1. $ docker-compose down -v我发现这实际上并没有删除数据库卷。运行docker volume ls静止图像会显示过去存在的卷。
  2. $ docker volume prune这将清除卷。运行docker volume ls后运行显示一个空列表。
  3. $ rm -rf ./cms/conf/mysql这会清除 db 容器所做的任何实际文件系统更改。
  4. $ docker-compose up -d --build重建容器。这应该会触发我的初始化 SQL 脚本。

Docker 运行,db容器成功创建。我能够访问adminerlocalhost:8080. 我可以使用文件root中指定的密码以用户身份登录docker-compose.yml

Adminer 界面显示标准 MySQL 数据库 ( information_schema, mysql, performance_schema) 并另外显示在文件值中wordpress定义的数据库。但是我的数据库无处可寻。MYSQL_DATABASEdocker-compose.ymltestinit.sql

我发现了一些其他类似的 StackOverflow 问题也有类似的问题。我遵循了公认的答案,但仍然无法执行任何 SQL 脚本。

  1. docker-compose.yml,postgress,如何在 init.sql 文件中设置 db、tables 和 prepop?
  2. docker compose 初始数据库设置问题一次
  3. mySQL 初始化脚本未与 docker-compose 一起运行
  4. 在 docker-compose 启动时创建数据库

这是我db容器中的 Docker 日志。我没有看到任何看起来很奇怪的东西。没有关于初始化等的错误消息:

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !

To do so, start the server, then issue the following commands:


'/usr/bin/mysqladmin' -u root password 'new-password'

'/usr/bin/mysqladmin' -u root -h password 'new-password'


Alternatively you can run:

'/usr/bin/mysql_secure_installation'


which will also give you the option of removing the test

databases and anonymous user created by default. This is

strongly recommended for production servers.

[编辑] 我登录到db容器的 CLI,并验证我的 init.sql 脚本位于 docker-entrypoint-initdb.d 文件夹中:

$ cd docker-entrypoint-initdb.d
$ ls
init.sql
$ pwd
/docker-entrypoint-initdb.d

有人对还有什么要检查的有任何想法吗?

我遇到了同样的问题,我更仔细地调查了日志。我不确定以下错误是否相关,但我决定摆脱它。

ERROR 1396 (HY000) at line 1: Operation CREATE USER failed for 'root'@'%'

似乎root用户是默认创建的,所以我将environment用户的变量更改user为例如而不是root

MYSQL_USER: user

之后,我构建并运行了docer-compose.yml文件,SQL脚本成功执行。
