So far I have tried everything I could find on the internet - but nothing seems to help.

This is my docker-compose.yml file:

version: '3.3'



services:

  ivs_fraud:

    build:

      context: .

      args:

        GIT_SSH_KEY: ${GIT_SSH_KEY}

    image: ivs_fraud:latest

    container_name: fraud

    depends_on:

      - ivsdb

    links:

      - ivsdb

    networks:

      - database_network



networks:

  database_network:

    driver: bridge

And I have a link / dependency to ivsdb service which is defined in another docker-compose-dev.yml file:

version: '3.3'



services:

  ivsdb:

    image: mysql

    container_name: ivsdb

    networks:

      - database_network

    ports:

      - ${DEFAULT_DB_PORT}:3306

    restart: always

    environment:

      MYSQL_DATABASE: ${DEFAULT_DB_NAME}

      MYSQL_USER: ${DEFAULT_DB_USER}

      MYSQL_PASSWORD: ${DEFAULT_DB_PASS}

      MYSQL_ROOT_PASSWORD: ${DEFAULT_DB_ROOT_PASS}

This is my .env file (Django reads this .env file and creates a connection according to it):

DEFAULT_DB_NAME=ivsdb

DEFAULT_DB_HOST=ivsdb

DEFAULT_DB_PORT=10001

DEFAULT_DB_USER=root

DEFAULT_DB_PASS=root

DEFAULT_DB_ROOT_PASS=root

And i keep getting:

(2003, 'Can't connect to MySQL server on 'ivsdb' (111 "Connection
refused")')

There are several modifications that i have tried with no success:

1. Move everything into one docker-compose file


2. Get rid of "networks" entry completely


3. Change hosts to ivsdb / 127.0.0.1 / localhost / 0.0.0.0
   

Things that work:

1. Djago service runs well


2. Mysql service runs well.

I can connect to it using command line:

mysql -uroot -proot -P10001 --protocol=tcp 

or

mysql -uroot -proot -P10001 -h127.0.0.1 (IP adress enforces tcp protocol)

Looks like Django is having some hard time connecting to mysql container. But judging by "Connection refused" - django can reach mysql container.

What am I missing?

DEFAULT_DB_PORT=10001 should actually be MySQL's default port (3306), not the host-mapped port (10001)

The difference is nicely explained here
