Below are the steps I have done to solve this.

1- Create env.yml file. The structure of this file looks like this.
`
// env.yml
local:
host: localhost
port: 5432
name: mydb
user: root
password: secret

dev:
host: db.myserver.com
port: 5432
name: mydb
user: root
password: secret
`

In the env.yml file there are two environment local and dev. local is testing on local development environment variables. dev is for the cloud hosting environment.

2- To reference env.yml in serverless.yml so that we deploy microservice based on the env variables i.e. sls deploy --s local or sls deploy --s dev

// serverless.yml provider: stage: local environment: ${file(./env.yml):${opt:stage, self:provider.stage}}

That's all we need, to configure the multi-env. I have customised it further so that we don't need to run sls deploy --s local. The environment picks automatically local and all we need is sls deploy command.

3- Lastly, if you need to refer the variables in .js files all you need to do is call them like
// PostgreSQL database connection parameters: var config = { host: process.env.host, port: process.env.port, database: process.env.name, user: process.env.user, password: process.env.password, };

I hope above solves lot of issues.

Kind regards,
