How can I deploy an AWS Lambda function using CircleCI?

To deploy an AWS Lambda function using CircleCI, you need to set up a CircleCI configuration file that includes the necessary steps for building and deploying your function.

What should I include in the CircleCI config file?

You should include jobs for installing dependencies, running tests, and deploying the function using AWS CLI commands.

Can you provide a sample CircleCI config file?

Sure! Here's a basic example:

version: 2.1
jobs:
  deploy:
    docker:
      - image: circleci/python:3.8
    steps:
      - checkout
      - run:
          name: Install AWS CLI
          command: pip install awscli
      - run:
          name: Deploy to AWS Lambda
          command: aws lambda update-function-code --function-name my-function --zip-file fileb://function.zip
workflows:
  version: 2
  deploy:
    jobs:
      - deploy

What are the prerequisites for this deployment?

You need to have an AWS account, the AWS CLI installed, and your Lambda function code packaged properly.
