Database is not created on docker compose up -d - docker

Question

I'm following the docs of mariadb. It says that the db should be created if it find a .sql in /docker-entrypoint-initdb.d.
I'm working on a Ubuntu Server in a Oracle Virtual BOX VM.
My docker-compose.yml looks like this:
version: "3.9"
services:
db:
image: mariadb:10
container_name: mariadb
ports:
- 3306:3306
environment:
- MYSQL_USER=user
- MYSQL_ROOT_PASSWORD=password
- MYSQL_PASSWORD=password
- MARIADB_DATABASE=database // tried with MYSQL_DATABASE and without this line
volumes:
- "db_data:/var/lib/mysql"
- ".database/initdb/dump.sql:/docker-entrypoint-initdb.d/initdb.sql"
# networks:
# - network
volumes:
db_data:
My initdb.sql looks like this (the one that should work in the end looks different but out of simplicity I reduced it to the max and could not even this simple one working):
CREATE DATABASE NEWDB;
I honestly don't know where to look or what to do now because everywhere I looked for a possible solution I found that this is the bare minimum example that should work.
I tried to restarted docker, deleted all containers, images and volumes, modified the initdb.sql into:
CREATE USER user WITH PASSWORD 'password';
CREATE DATABASE IF NOT EXISTS database;
GRANT ALL PRIVILEGES ON DATABASE database TO user;
but the database is not initialized when I docker compose up.
I looked up the container and the initdb.sql was there.
EDIT: It somehow worked, when I docker compose up with MARIADB_DATABASE=database but the script initdb.sql still doesn't work and it's the most important thing because it set's up the whole database.
(NOTE: On top of that I want to set up another PHP-container that runs a PHP-script in order to collect data that is being stored in the above MariaDB-container. The MariaDB is connected with a website that calls data from the container)

Answer 1

Well I'm using the following stack and it works fine for me.
php-apache:
This is an Apache server that runs all my php scripts. You can place your scripts in ./src directory and it will automatically be mounted to DocumentRoot directory of the Apache server.
db:
This the latest docker container of MariaDb
adminer:
This is the lite-weight database browser which I use for creating and altering my databases. You can just visit localhost:8081 and then enter the following credentials. It becomes simpler to manage the databases this way.
username: root
password: example
version: '3.8'
services:
php-apache:
container_name: php-apache
build:
context: .
dockerfile: Dockerfile
image: php:8.0-apache
volumes:
- ./src:/var/www/html/
ports:
- 8080:80
db:
image: mariadb
restart: always
environment:
MARIADB_ROOT_PASSWORD: example
adminer:
image: adminer
restart: always
ports:
- 8081:8080
Dockerfile:
This is a simple docker container which is extended from the base php:8.0-apache image, with mysql extensions installed in it for PDO support.
FROM php:8.0-apache
RUN docker-php-ext-install pdo_mysql
RUN docker-php-ext-install mysqli && docker-php-ext-enable mysqli
RUN apt-get update && apt-get upgrade -y
P.S:
Here you'll have to create all your databases manually via GUI of Adminer. But if you prefer SQL queries via initdb.sql then be my guest. I've just provided this configuration as a suggestion.

Answer 2

I came up with a solution. I used a base image of laravel (installed the laravel project with <curl -s "https://laravel.build/project-name?with=mariadb" | sudo bash> and modified it a little bit. So here's the docker-compose.yml:
# For more information: https://laravel.com/docs/sail
version: '3'
services:
laravel.test:
build:
context: ./vendor/laravel/sail/runtimes/8.1
dockerfile: Dockerfile
args:
WWWGROUP: '${WWWGROUP}'
image: sail-8.1/app
extra_hosts:
- 'host.docker.internal:host-gateway'
ports:
- '${APP_PORT:-80}:80'
- '${VITE_PORT:-5173}:${VITE_PORT:-5173}'
environment:
WWWUSER: '${WWWUSER}'
LARAVEL_SAIL: 1
XDEBUG_MODE: '${SAIL_XDEBUG_MODE:-off}'
XDEBUG_CONFIG: '${SAIL_XDEBUG_CONFIG:-client_host=host.docker.internal}'
volumes:
- '.:/var/www/html'
networks:
- sail
depends_on:
- mariadb
mariadb:
image: 'mariadb:10'
container_name: 'mariadb-10'
ports:
- '${FORWARD_DB_PORT:-3306}:3306'
environment:
MYSQL_ROOT_PASSWORD: '${DB_PASSWORD}'
MYSQL_ROOT_HOST: "%"
MYSQL_DATABASE: '${DB_DATABASE}'
MYSQL_USER: '${DB_USERNAME}'
MYSQL_PASSWORD: '${DB_PASSWORD}'
MYSQL_ALLOW_EMPTY_PASSWORD: 'yes'
volumes:
- 'sail-mariadb:/var/lib/mysql'
- './vendor/laravel/sail/database/mysql/create-testing-database.sh:/docker-entrypoint-initdb.d/10-create-testing-database.sh'
networks:
- sail
healthcheck:
test: ["CMD", "mysqladmin", "ping", "-p${DB_PASSWORD}"]
retries: 3
timeout: 5s
networks:
sail:
driver: bridge
volumes:
sail-mariadb:
driver: local
Here you can see that the "10-create-testing-database.sh" is executed on startup. I tested this container and it created a database, so I just had to modify it a little bit and now the container creates a database and tables on container startup. Here's the "10-create-testing-database.sh":
#!/usr/bin/env bash
mysql --user=root --password="$MYSQL_ROOT_PASSWORD" <<-EOSQL
CREATE DATABASE IF NOT EXISTS database_name;
GRANT ALL PRIVILEGES ON \`testing%\`.* TO '$MYSQL_USER'#'%';
USE database_name;
CREATE TABLE IF NOT EXISTS table_name(
table_entries ...
);
EOSQL
I still don't know why my initial setup did not work. The only difference I see is that this working file is a .sh and the not working one is a .sql (this does not make sence to me but it what it is).
