Can not connect to database

[adiatma85]

Hello @victorsteven , first, I like to say thank you about the tutorial that you write here

I have some kind of problem when use this repository as reference, when I run docker-compose up
the app can not run and have error messages like this

In docker-compose.yml, the configuration is like this

fullstack-mysql:
    image: mysql:5.7
    container_name: full_db_mysql
    ports: 
      - 3306:3306
    environment: 
      - MYSQL_ROOT_HOST=${DB_HOST} 
      - MYSQL_USER=${DB_USER}
      - MYSQL_PASSWORD=${DB_PASSWORD}
      - MYSQL_DATABASE=${DB_NAME}
      - MYSQL_ROOT_PASSWORD=${DB_PASSWORD}
    volumes:
      - database_mysql:/var/lib/mysql
    networks:
      - fullstack

(It's sync with .env file)
I can not figure out why I found error while running docker-compose, but I can assure that mysql container is running

Any one have a lead why this is happen?
Thanks in advance

Somehow, it's resolved itself.

I kinda somehow figured what happen, maybe it's because I forgot do run docker-compose up --build

The container kinda piled up with another container. So to make sure it doesn't conflict with another container, what I am doing is:

• Make sure that there is separate container
• If there is not exist, run docker-compose up with --build flag
