Question

我正在尝试让我的docker db容器在创建时自动使用数据集填充数据库。根据{{3}}，卷中有一个docker-entrypoint-initdb.d文件夹可用于此目的。

我设置了docker-compose.yml文件以镜像在StackOverflow上找到的示例，但是仍然无法使我的SQL脚本执行。这是我的docker-compose.yml文件的相关内容：

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docker-compose.yml文件旁边，我有一个cms/sql/init.sql文件，内容如下：

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：

$ 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仍会显示过去的卷。
$ docker volume prune这将清除卷。运行docker volume ls后运行此列表将显示一个空列表。
$ rm -rf ./cms/conf/mysql这将清除db容器所做的任何实际文件系统更改。
$ docker-compose up -d --build要重建容器。这应该会触发我的初始化SQL脚本。

Docker运行，并且db容器成功创建。我可以访问在adminer上运行的localhost:8080容器。我可以使用root文件中指定的密码作为docker-compose.yml用户登录。

Adminer界面显示标准MySQL数据库（information_schema，mysql，performance_schema），并另外显示在wordpress值中定义的MYSQL_DATABASE数据库docker-compose.yml文件。但是我的test数据库init.sql找不到了。

我发现其他一些类似的StackOverflow问题也有类似的问题。我已经遵循了可接受的答案，但是仍然无法获取任何SQL脚本来执行。

这是我的db容器中的Docker日志。我没有看到任何看起来很奇怪的东西。没有有关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] 我登录了db容器的CLI，并验证了我的init.sql脚本是否在docker-entrypoint-initdb.d文件夹中：

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

任何人对要检查的东西有什么想法？

Answer 1

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'@'%'

似乎默认创建了 root 用户，因此我将用户的 environment 变量更改为 user 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。

docker-compose mariadb docker-entrypoint-initdb.d sql未执行
