docker-compose mariadb docker-entrypoint-initdb.d sql is not executed

Question

I am attempting to have my docker db container automatically populate the database with a dataset when created. According to the mariadb documentation, there is an docker-entrypoint-initdb.d folder in the volume that can be used for this purpose.

I set up my docker-compose.yml file to mirror examples that I have found on StackOverflow, but am still unable to get my SQL scripts to execute. Here are the relevant pieces of my docker-compose.yml file:

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

Next to the docker-compose.yml file, I have a cms/sql/init.sql file with the following contents:

CREATE DATABASE /*!32312 IF NOT EXISTS*/ `test` /*!40100 DEFAULT CHARACTER SET utf8mb4 */;
USE `test`;

Prior to each test iteration, I clean up any old/cached Docker content:

$ docker-compose down -v I've found this doesn't actually remove the db volumes. Running a docker volume ls still shows past volumes present.
$ docker volume prune This clears out the volumes. Running docker volume ls after running this shows an empty list.
$ rm -rf ./cms/conf/mysql This cleans out any actual filesystem changes that the db container made.
$ docker-compose up -d --build To rebuild the containers. This should trigger my initialization SQL scripts.

Docker runs, and the db container gets successfully created. I am able to access the adminer container running on localhost:8080. I am able to log in as the root user with the password specified in the docker-compose.yml file.

The Adminer interface shows the standard MySQL databases (information_schema, mysql, performance_schema) and additionally shows the wordpress database defined in the MYSQL_DATABASE value of the docker-compose.yml file. But my test database from the init.sql is nowhere to be found.

I found some other similar StackOverflow questions that have had similar problems. I've followed the accepted answers, and am still unable to get any SQL scripts to get executed.

docker-compose.yml, postgress, how to setup db, tables and prepop in an init.sql file?
Issue with docker compose initial DB setup once
mySQL init scripts not running with docker-compose
Create database on docker-compose startup

Here's the Docker log from my db container. I didn't see anything that looked strange; no error messages about initialization, etc:

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !

To do so, start the server, then issue the following commands:


'/usr/bin/mysqladmin' -u root password 'new-password'

'/usr/bin/mysqladmin' -u root -h password 'new-password'


Alternatively you can run:

'/usr/bin/mysql_secure_installation'


which will also give you the option of removing the test

databases and anonymous user created by default. This is

strongly recommended for production servers.

[Edit] I logged into the CLI for the db container, and verified that my init.sql script is in the docker-entrypoint-initdb.d folder:

$ cd docker-entrypoint-initdb.d
$ ls
init.sql
$ pwd
/docker-entrypoint-initdb.d

Anyone have any ideas on what else to check?

I faced an identical issue and I investigated the logs more closely. I wasn't sure if the following error was related but I decided to get rid of it.

ERROR 1396 (HY000) at line 1: Operation CREATE USER failed for 'root'@'%'

It seems that root user is created by default so I changed the environment variable of the user to user for example instead of root:

MYSQL_USER: user

After that I built and run the docer-compose.yml file and the SQL scripts executed succesfuly.
