如何从代码管道调用awscli命令?

exports.copyRepoToProdS3 = (event, context) => {
  const jobId = event['CodePipeline.job'].id
  const s3Location = event['CodePipeline.job'].data.inputArtifacts[0].location.s3Location
  const cpParams = JSON.parse(event['CodePipeline.job'].data.actionConfiguration.configuration.UserParameters)

  let promises = []
  for (let bucket of prodBuckets) {
    let params = {
      Bucket: bucket,
      CopySource: s3Location['bucketName'] + '/' + s3Location['objectKey'],
      Key: cpParams['S3ObjectKey']
    }

    promises.push(s3.copyObject(params).promise())
  }

  return Promise.all(promises)
    .then((data) => {
      console.log('Successfully copied repo to buckets!')
    }).catch((error) => {
      console.log('Failed to copy repo to buckets!', error)
    })
}
