Docker Compose Sql DB image connection error












-1














I have a docker-compose.yml file and I want to create three containers to run my node app: a client, a server, a db container with some data.



I have troubles to create the db container and connect it to the server container, I'm using sequelize to connect with db, but on docker-compose up command I have connection error on server app startup:




server_1 | Unable to connect to SQL database: webgrit_superactivation { SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306




this is my docker-compose file:



version: "3"

services:
# client
client:
image: "ngapp"
build: "client/dist/."
ports:
- "4200:80"
# Server
server:
image: "exapp"
build: "server/."
ports:
- "3000:3000"
links:
- db
# MySQL
db:
image: mysql:5.7
command: mysqld --user=root
volumes:
- ./mysql-dump:/docker-entrypoint-initdb.d
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_USER: myuser
MYSQL_PASSWORD: mypass
MYSQL_DATABASE: mydbname


in the mysql image I use a data.sql dump file to init my db, but something is wrong



this is my server container dbconfig.js file that I use to connect with mysql db:



CONFIG.db_name = process.env.DB_NAME_DEV || "mydbname";
CONFIG.db_user = process.env.DB_USER_DEV || "myuser";
CONFIG.db_password = process.env.DB_PASSWORD_DEV || "mypass";
CONFIG.db_dialect = process.env.DB_DIALECT_DEV || "mysql";
CONFIG.db_host = process.env.DB_HOST_DEV || "localhost";
CONFIG.db_port = process.env.DB_PORT_DEV || "3306";


and this is the start of my data.sql dump file:



SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET AUTOCOMMIT = 0;
START TRANSACTION;
SET time_zone = "+00:00";

CREATE DATABASE IF NOT EXISTS `mydbname` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
USE `mydbname`;

CREATE TABLE `users` (
...


Edit: here you can find an error log: https://github.com/ufollettu/SEANSA/blob/master/docker%20error%20log.log



I'm pretty new to docker, how can I solve this problem?
thanks for help
