Docker docker-entrypoint-initdb.d/ scripts with Mongodb aren't working

Question

I have been struggling to configure the execution of scripts via /docker-entrypoint-initdb.d in a Mongo container in Docker.

I have tried to follow the documentation carefully, but without success.

project structure

docker-compose.yml

version: '3.3'
services:
  mongodb:
    image: mongo:latest
    container_name: mongo_db
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: rootpass
      MONGO_INITDB_DATABASE: database
    volumes:
      - mongodbdata:/data/db
      - ./init.d/:/docker-entrypoint-initdb.d/
    restart: always
volumes:
  mongodbdata:
    driver: local

init-mongo.sh

#!/bin/bash
echo 'hello script'

In the logs the command echo 'hello script' is not executed.

What should I do? Is there something I'm missing?

Answer 1

Docker only executes scripts inside docker-entrypoint-initdb.d upon creation of the image as this is mostly used for seeding data. If it's not a fresh image and you're just trying to spawn it again with your script then that's what caused it.

What you can try to do is type this in your terminal:

docker stop $(docker ps -aq) && docker rm $(docker ps -aq) && docker rmi mongo:latest -f && docker-compose up

Then check the logs:P
