How can I manage environment variables for AWS Lambda in CircleCI?

You can manage environment variables for AWS Lambda in CircleCI by using the CircleCI environment variable settings or by defining them in your config.yml file.

Can you show me an example of how to set this up in the config.yml?

Sure! In your .circleci/config.yml, you can define environment variables like this:

version: 2.1
jobs:
  build:
    docker:
      - image: circleci/python:3.8
    environment:
      MY_ENV_VAR: 'value'
    steps:
      - checkout
      - run:
          name: Deploy to AWS Lambda
          command: aws lambda update-function-configuration --function-name my-function --environment Variables={MY_ENV_VAR=value}

What if I want to keep my environment variables secret?

You can use CircleCI's context feature to manage sensitive environment variables securely. Create a context and add your variables there, then reference the context in your job.

Is there a limit to the number of environment variables I can set?

Yes, AWS Lambda has a limit of 4 KB for the total size of all environment variables combined. Make sure to keep that in mind!
