Windows 7上的Docker-compose：使用Yaml文件时如何导入数据库转储？

Question

I'm started from here: https://docs.docker.com/compose/wordpress/

I got this running well on my windows 7

version: '2'

services:
   db:
     image: mysql:5.7
     volumes:
       - db_data:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: wordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "8000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_PASSWORD: wordpress

  phpmyadmin:
    container_name: phpmyadmin
    depends_on:
      - db
    image: phpmyadmin/phpmyadmin:latest
    environment:
      MYSQL_ROOT_PASSWORD: "mysql_root_password"
      PMA_ARBITRARY: 1
    restart: always
    ports:
     - 8080:80
    volumes:
     - /sessions
volumes:
    db_data:

My question is: how can I import a db-dump from a Windows Machime? My goal is to work locally on a dump of the production (I've already have the dump in the same folder of my docker-compose.yaml file).

Answer 1

If you bash into the MySQL container and the DB was created and the data imported then your first issue is fix.

Regarding the second one I'm not able to login from within phpMyAdmin and because I am not seeing the service listed on your docker-compose.yml I would recommend to install and configure it following the docs at phpmyadmin . Very important read the ENV variables here since you need to setup them in order to allow the phpMyAdmin container read/write from/to the MySQL container.

Ex (from here ):

phpmyadmin:
    image: phpmyadmin/phpmyadmin
    container_name: phpmyadmin
    environment:
     - PMA_ARBITRARY=1
    restart: always
    ports:
     - 8080:80
    volumes:
     - /sessions

You're missing this part on your Dockerfile or maybe you don't get just yet how Docker works at all which lead me to recommend you to read a bit about it.

UPDATE

Since the answer is non longer related to phpMyAdmin and now turns into docker volumes under Windows here is the updated answer.

Mount volumes on Windows work as in Linux, ex:

php-fpm:
    build: docker/php-fpm
    volumes:
        - ./sources:/data/www

The service definition above will work on both OS, you can try it here . I am using latest Docker for Windows (the Beta tagged as RCXX)

Now a workaround for your case could be either mount a host volume where you have the .sql dump file or use the COPY command from Docker to move the file inside the container and then use RUN or a bash script to import it back to the DB.

Answer 2

One way that you can do this is to mount a folder with the dump into the directory /docker-entrypoint-initdb.d/ when using the official mysql image.

This is a pretty good solution for working in a team, where everyone should be working off the same base db. You can read more about that in the documentation. This will only occur on the first run of the container. If you delete the container, it will do a fresh import. This has it's uses as well.

More often, I do as some of the other answers suggest:

docker-compose exec db mysql -u root -p DB_NAME < DUMP_FILE_IN_CONTAINER

It's important to note, that you still need to mount the dump file in the container! It will not work for a file on the host machine!

You don't necessarily need to mount an entire folder (though you can - all scripts in the above-mentioned folder will execute in alphabetical order). You can just mount your dump file like this:

services:
  db:
  image: mysql:5.7
  volumes:
    - db_data:/var/lib/mysql
    - ./path/to/dump/on/host.sql:/docker-entrypoint-initdb.d/anyname.sql
  restart: always
  environment:
    MYSQL_ROOT_PASSWORD: wordpress
    MYSQL_DATABASE: wordpress
    MYSQL_USER: wordpress
    MYSQL_PASSWORD: wordpress
