Is there a way to define a common env variable in aws lambda layer?

Question

I use serverless framework and I have multilple aws node.js lambdas that share the same layer. I want to define an ENV variable for all of them-is there a way to put that common ENV variable into the layer's serverless.yml? Or do I have to go and put it in each serverles.yml files separately?

Put them in a common file and import that common file into each deployment's serverless.yml template? See serverless.com/framework/docs/providers/aws/guide/variables/… — jarmod

@Capaj were you able to find a satisfactory solution for environment vars in layers? — trdavidson

@trdavidson yeah we're using serverless-dotenv-plugin and it works fine for our fleet of lambdas — Capaj

To deal with env variables in my lambdas i use this plugin https://www.npmjs.com/package/serverless-dotenv-plugin

It looks for a .env file use it as a reference to your env variables.

plugins:
  - serverless-dotenv-plugin

Hope it helps.
