Docker - SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306
I'm trying to get my nodejs application up and running using a docker container. I have no clue what might be wrong. The credentials seems to be passed correctly when I debug the credentials with the console. Also firing up sequel pro and connecting directly with the same username and password seems to work. When node starts in the container I get the error message:
SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306
The application itself is loading correctly on port 3000, however no data is retrieved from the database. If have also tried adding the environment variables directly to the docker compose file, but this also doesn't seem to work.
My project code is hosted over here: https://github.com/pietheinstrengholt/rssmonster
The following database.js configuration is used. When I add console.log(config) the correct credentials from the .env file are displayed.
require('dotenv').load();
const Sequelize = require('sequelize');
const fs = require('fs');
const path = require('path');
const env = process.env.NODE_ENV || 'development';
const config = require(path.join(__dirname + '/../config/config.js'))[env];
if (config.use_env_variable) {
var sequelize = new Sequelize(process.env[config.use_env_variable], config);
} else {
var sequelize = new Sequelize(config.database, config.username, config.password, config);
}
module.exports = sequelize;
When I do a console.log(config) inside the database.js I get the following output:
{
username: 'rssmonster',
password: 'password',
database: 'rssmonster',
host: 'localhost',
dialect: 'mysql'
}
Following .env:
DB_HOSTNAME=localhost
DB_PORT=3306
DB_DATABASE=rssmonster

Inside of the container you should reference the container by the name you gave in your docker-compose.yml file.
In this case you should use
DB_HOSTNAME: mysql
