Docker: how to use SQL file in Directory - mysql

Question

I'm trying to open a Wordpress website locally with Docker.
Here is the docker-compose.yml file for this container:
version: '3'
services:
db:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: somewordpress
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_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
volumes:
db_data:
The Dockerfile:
FROM orchardup/php5
ADD . /code
In the terminal, I enter docker-compose up -d. I can then visit the site at localhost:8080, but it's not the actual website - it's just a Wordpress template. I'm guessing I have to incorporate the .sql file in the directory somehow? How would I go about doing this? Do I need to specify this in the .yml file?

Just add a volume mapping to map a local folder to the /docker-entrypoint-initdb.d container folder, for example : ./init-db:/docker-entrypoint-initdb.d. This file will be loaded on the first container startup.
Considering the docker-compose.yml bellow :
drop your sql files into /path-to-sql-files-on-your-host host folder)
run docker-compose down -v to destroy containers and volumes
run docker-compose up to recreate them.

According to the MySQL-Docker documentation, you have a couple of options.
After the 'db' docker is running, simply connect to it using the mysql client, and import your .sql dump. Read the section 'Connect to MySQL from the MySQL command line client' If you where not using docker, you would restore this backup like this mysql fooDB < fooDB_dump.sql It will be similar with docker commands.
Docs, "Initializing a fresh instance", says "...it will execute files with extensions .sh, .sql and .sql.gz that are found in /docker-entrypoint-initdb.d" That looks more like what you want. Just copy your .sql file into that location within the docker image and then it will automatically parse it.
