Kubernetes 如何限制Apache Flink任务管理器日志大小

我正在使用duc检查磁盘使用情况，最终发现ApacheFlink占用超过2GB的空间，那么如何将日志大小限制在100MB以下呢？我的ApacheFlink部署在Kubernetes（v1.15.2）集群中

我已经在互联网上搜索，并像这样调整我的配置，但仍然无法工作：

flink-conf.yaml:
jobmanager.rpc.address: flink-jobmanager
taskmanager.numberOfTaskSlots: 6
blob.server.port: 6124
jobmanager.rpc.port: 6123
taskmanager.rpc.port: 6122
jobmanager.heap.size: 1024m
taskmanager.memory.process.size: 1024m
log4j.properties:
log4j.rootLogger=INFO, file
log4j.logger.akka=INFO
log4j.logger.org.apache.kafka=INFO
log4j.logger.org.apache.hadoop=INFO
log4j.logger.org.apache.zookeeper=INFO
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.file=${log.file}
log4j.appender.file.MaxFileSize=50MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p %-60c %x - %m%n
