desktop_mysql-docker-nariadi_1 exited with code 0

When I run docker-compose up, mysql-docker-nariadi service exists with code 0. Shell script is executing and .sql file as well. How can I prevent from exiting?

Answer 1

You need to run your image in daemon mode - that's how they do it in the official MySQL image:

ENTRYPOINT ["mysqld"]

In your specific case, you can run "mysqld" at the end of your entrypoint SH file /mysql/setup.sh .

Answer 2

In order to import dump when container is strted you need just add it to docker-compose file using volume directives:

volumes:
  - ./dump.sql:/docker-entrypoint-initdb.d/dump.sql

No need to use ENTRYPOINT . It should look:

mysql-docker-nariadi:
    image: mysql:5.6
    ports:
        - "3310:3306"
    volumes:
      - ./dump.sql:/docker-entrypoint-initdb.d/dump.sql
