archiveLogs can only get partial logs

[wshi5985]

We send main container logs to s3 bucket, here is the config

artifactRepository:
  # archiveLogs will archive the main container logs as an artifact
  archiveLogs: true
  s3:
    endpoint: s3.amazonaws.com
    bucket: <bucket_name>
    region: us-east-1
    useSDKCreds: true

after workflow job finishes, we see the main.log in s3 bucket, but only partial logs there, same as what we can see from kubectl logs <workflow_pod_name> command, looks like the container log file rotated on the node. both kubectl logs command and the archiveLog in s3 bucket only have the most recent log lines. is there any way we can get the rotated logs send to s3 bucket?

Thanks.
