title: How to add files from S3 bucket to output artifacts in AWS CodePipeline? (NodeJS)
body: <p>I am using a AWS CodePipeline which fetches the source from my git repository, uses <code>CodeBuild</code> buildSpec to build and save output artifacts to S3 bucket, which ultimately gets deployed to <code>Elastic BeanStalk</code> (NodeJS Environment).</p>
  <p>Everything works fine but I require the pipeline to copy 1 particular file from one of my <code>AWS S3</code> buckets and add it to the <code>output artifacts</code> before deploying it to the <code>EB</code></p>
  <p>Can it be done using the buildSpec?</p>
  <pre><code>artifacts:
    files:
      - '**/*'
      # - How to add a file from S3 to the artifacts?
