Elasticsearch 1.7.4 log rotation - elasticsearch

Question

I'm trying to use logging.yml ( Elasticsearch file ) + logrotate configuration for elasticsearch log rotation .

I don't want to keep any rotated files ...

layout:
type: pattern
conversionPattern: "[%d{ISO8601}][%-5p][%-25c] %m%n"
Logrotate configuration :
/var/log/elasticsearch/*.log {
daily
rotate 0
copytruncate
compress
delaycompress
missingok

My question are :
Why the dba01es.d1.log.1 file is not compressed ?
Why the rotate 0 is not working here ? and logrotate keep saving the rotate file ....
Thanks a lot !
