我想在Docker容器中创建MySql数据库并在容器启动时在其中执行一些DDL和DML语句

Question

This is my docker-compose.yml file

version: "3.5"
services:
  docker-mysql:
    image: mysql:5.7
    container_name: docker-mysql
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_DATABASE=user_management
      - MYSQL_PASSWORD=password

The default database is created "user_management" and now I have files with DDL and DML statements in it that I want to execute ie DDL statement (create a table) and DML statements (Insert few users by default). Not by entering the bash and manually executing the statements but any automated docker way of loading the files that contain DDL and DML statements and execute it.

Answer 1

In mysql dockerhub says, files with extensions .sh, .sql and .sql.gz that are found in /docker-entrypoint-initdb.d will be executed in the startup of container to the database specified by the MYSQL_DATABASE variable.

version: "3.5"
services:
  docker-mysql:
     image: mysql:5.7
     container_name: docker-mysql
     environment:
       - MYSQL_ROOT_PASSWORD=password
       - MYSQL_DATABASE=user_management
       - MYSQL_PASSWORD=password
     volumes:
       - /yourscript:/docker-entrypoint-initdb.d

so as above, you can mount volume and add your DDL and DML scripts in that location. Then mysql would execute them on startup. /yourscript is the location of your scripts
