MySQL Docker image keeps shutting down - mysql

Question

I am trying to build two docker images for the two components of by project. One is a node application and the other is the MySQL DB. I am using a script to create the databases and fill up the tables in the DB docker image because I couldn't create stored procedures using the ORM. My configuration for it is like this:
FROM mysql:8.0.26
ADD initialization.sql /docker-entrypoint-initdb.d
ENV MYSQL_ALLOW_EMPTY_PASSWORD=thisisfine
EXPOSE 3306
When I run docker-compose up --build, the database image shuts down which causes issues with my other image. I am unable to figure out why. This is what is present in the logs:
Creating libraryly_db_1 ... done
Creating libraryly_backend_1 ... done

I can't figure out what is causing the root user to send a shutdown request. Please help.

Answer 1

in this case You don't need a dockerfile if you're using docker-compose, you can configure your docker-compose file like this
version: "3.7"
services:
mysql:
image: mysql:8.0.17
container_name: localmysql
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_ROOT_PASSWORD: 123456
MYSQL_DATABASE: initialDatabaseName
ports:
- 3306:3306
volumes:
- /your_local/path:/var/lib/mysql
if you want to initialize your db I recommend you to use an ORM what allow you to use database migrations, or run your script from your backend
