Setting the env using a .env file in Serverless

Using the Serverless framework, I want to be able to change the AWS region from an envrionment variable.

provider:
  name: aws
  region: ${env:AWS_REGION}

Then, AWS_REGION can be set to eu-west-2.

However, I want to have that set in a .env file:

AWS_REGION=eu-west-2

And then have that .env read by Serverless.

There are many topics about setting variables in the serverless.yml file, and exporting them from that file, but I want to put them into the file.

use this plugin to write .env with serverless.yaml serverless-export-env. so you just need to overwrite your region inside serverless yaml, and your env will be generated based on whay you've written in serverless.yaml.

Serverless now supports .env files without the need for a plugin

  1. Add useDotenv: true to your serverless.yml file. The variable should be at the root level, same as service: ...

  2. Add a .env file at the root of your project and serverless will load the variables.

Example:

// .env
MY_TABLE=A_TABLE_NAME

Out of the box serverless doesn't parse .env, that part belongs to you.

I see three options for you:

  1. Use the serverless-dotenv-plugin.

  2. Write a script that exports .env vars to your local environment before you run serverless.

  3. Run serverless in docker-compose which is .env aware -- I use this in combination with Makefile, even in a CI/CD context.
