npx sequelize-cli db:migrate command don't read the environment variables with PM2

What you are doing?

npx sequelize-cli db:migrate command don't read the environment variables

This command works without problems in my local environment on macOS Sonoma 14.2.1 but when I try to run it in a development environment (PM2 version 5.3.1) it does not work

.sequelizerc

const path = require('path');

module.exports = {
    'config': path.resolve('src/db/config', 'config.cjs'),
    'models-path': '../src/db/models/',
    'migrations-path': path.resolve('src/db', 'migrations'),
    'seeders-path': path.resolve('src/db', 'seeders'),
}

config.cjs

const config = require('../../common/config.js');

module.exports = {
  development: {
    username: config.dbUser,
    password: config.dbPassword,
    database: config.dbName,
    host: config.dbHost,
    dialect: 'postgres',
    migrationStorageTableSchema: 'vic',
    logging: !config.isProd,
  },
  test: {
    username: 'root',
    password: null,
    database: 'database_test',
    host: '127.0.0.1',
    dialect: 'postgres',
  },
  production: {
    username: 'root',
    password: null,
    database: 'database_production',
    host: '127.0.0.1',
    dialect: 'postgres',
  },
};

common/config.js

require('dotenv').config();

const config = {
  env: process.env.NODE_ENV || 'dev',
  host: process.env.HOST || 'localhost',
  port: process.env.PORT || 3000,
  dbHost: process.env.DB_HOST,
  dbPort: process.env.DB_PORT,
  dbName: process.env.DB_NAME,
  dbUser: process.env.DB_USER,
  dbPassword: process.env.DB_PASSWORD,
  isProd: process.env.NODE_ENV === 'production',
};

module.exports = config;

What is actually happening?

I am getting this message in the terminal, where it is not reading the environment variables and is not creating the models in the database

I tried printing the variables and either way I'm getting undefined

Workaround
My application runs inside PM2 and the environment variables are injected from the ecosystem.config.js configuration file

After creating the .env file with the environment variables, the sequelize-cli db:migrate command ran without errors

I think sequelize-cli can't read environment variables injected by PM2

[himharsh1997]

@aobregonmx I try to run sequelize-cli command in the ec2 instance with inline environment variables but it doesn't work. To resolve the issue i need to set env globally for the current shell session using the command
export <ENV_NAME>=<ENV_VALUE>
<COMMAND_TO_RUN>

Is the sequelize-cli not able to use an inline environment variable.

[aobregonmx]

I think sequelize-cli runs outside of the PM2 environment and that's why it doesn't read the injected variables. When I have implemented CI it will carry out the process of creating the .env file as indicated in the comments of the official documentation Environment Variables Management
