无法使用 mysql docker 容器在 docker-entrypoint-initdb.d 中创建数据库

Question

I created a docker-compose.yml .

version: "3.7"
services:
  db:
    container_name: mysql
    image: mysql
    ports:
      - 3306:3306
    volumes:
      - ./sql:/docker-entrypoint-initdb.d
      - ./mysql:/var/lib/mysql
    environment:
      MYSQL_ROOT_USER : root
      MYSQL_ROOT_PASSWORD: root_pass
      MYSQL_DATABASE: wp1
      MYSQL_USER: wp
      MYSQL_PASSWORD: pass
    restart: always  

And in sql directory, I put a init.sql .

CREATE DATABASE IF NOT EXISTS wp2;

Then run docker-compose up .

In the log there is a entry for the init script.

mysql | 2020-04-08 02:17:32+00:00 [Note] [Entrypoint]: /usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/init.sql

But the database wp2 is not created.

$ docker exec -it mysql bash
# mysql -u wp -ppass
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| wp1                |
+--------------------+

How can I create a database with mysql container init script?

Answer 1

Your wp user doesn't have access rights on wp2.

Append to your sql file:

GRANT ALL on wp2.* to wp@'%';
