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

问题描述 投票：0回答：3

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。

我设置了 

docker-compose.yml
文件来镜像我在 StackOverflow 上找到的示例，但仍然无法执行 SQL 脚本。以下是我的 
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 

docker-compose.yml
文件旁边，我有一个 
cms/sql/init.sql
文件，其中包含以下内容：

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
    仍然显示过去的卷。
  2. $ docker volume prune
    这会清除卷。运行后运行 
    docker volume ls
    显示一个空列表。
  3. $ rm -rf ./cms/conf/mysql
    这会清除数据库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
容器已成功创建。我能够访问在 
adminer
上运行的 
localhost:8080
容器。我可以使用 
root
文件中指定的密码以 
docker-compose.yml
用户身份登录。

管理员界面显示标准 MySQL 数据库（

information_schema
、
mysql
、
performance_schema
），还显示 
wordpress
文件的 
MYSQL_DATABASE
值中定义的 
docker-compose.yml
数据库。但我的 
test
的 
init.sql
数据库无处可寻。

我发现其他一些类似的 StackOverflow 问题也有类似的问题。我已遵循已接受的答案，但仍然无法执行任何 SQL 脚本。

  1. docker-compose.yml，postgress，如何在 init.sql 文件中设置数据库、表和 prepop？
  2. docker compose 初始数据库设置一次的问题
  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

这是我的 

db
容器中的 Docker 日志。我没有看到任何奇怪的东西；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:

Alternatively you can run:

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

有人对还需要检查什么有任何想法吗？

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'@'%'

似乎默认创建了 

root
用户，因此我将用户的 
environment
变量更改为 
user
，而不是 
root
:

MYSQL_USER: user

之后，我构建并运行 

docker-compose.yml
文件，并且 
SQL
脚本成功执行。

我必须重置数据量，否则入口脚本将不会触发。在这种情况下，您必须删除所有内容：

sudo rm -rf /cms/conf/mysql/data/

您不能将要在 docker-entrypoint-initdb 上运行的脚本放入卷中，因为卷是在容器运行并且 docker-entrypoint-initdb 运行后创建的。

要使其工作，您需要创建一个 Dockerfile：

FROM mariadb:10.5.4-focal

COPY --chown=root cms/sql/* /docker-entrypoint-initdb.d/

你的 docker compose 文件将如下所示：

version: '3.6'
services:

  db:
    container_name: db
    build:
      context: .
    volumes:
      - ./cms/conf/mysql/data/:/var/lib/mysql/:rw
    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
