To set up AWS credentials, it's advisable to export them as environment variables. Here's a recommended approach:

코드:

export AWS_ACCESS_KEY_ID=".."
export AWS_SECRET_ACCESS_KEY=".."
export AWS_REGION="us-east-1"

retrive-logs-minutes-ago is the time range you want to fetch the logs, in this example, logs from 1 hour ago.

코드:

aws:
  waf-log-group-name: aws-waf-logs-cloudwatch-cloudfront
  region: us-east-1
  retrive-logs-minutes-ago: 60
