kubernetes - 如何限制 Apache Flink 任务管理器日志大小

Question

我正在使用 duc 检查磁盘使用情况，最后发现 Apache Flink 占用超过 2GB，那么如何限制日志大小小于 100MB？我的 Apache Flink 部署在 Kubernetes(v1.15.2) 集群中。

[root@uat-k8s-01 opt]# duc ls -Fg /var/lib/docker/overlay2/d1f441865d83867a21dd1dc0b11da2c75ffe1efe39209770cbd5e12e386df065/diff/opt/flink/log/
  1.9G flink--taskexecutor-0-flink-taskmanager-7f9df8fbf6-79746.log  [+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++]
  4.0K flink--taskexecutor-0-flink-taskmanager-7f9df8fbf6-79746.out  [                                                                                                                           ]

我已经从互联网上搜索并像这样调整我的配置，但仍然无法正常工作：

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:
