What is the method for cleaning up k8s logs?

In Kubernetes, you can use the following methods to clean up logs:

1. By using log rotation, you can configure a log rotation strategy in the container to limit log files to a specified size or number. For instance, you can set up log rotation to rename and create a new log file once a log file reaches a certain size.
2. Utilize logrotate tool: logrotate is a commonly used tool for managing log files, enabling users to configure it on the host machine to periodically clean up container log files.
3. Utilize a log collector to gather container logs into a centralized log storage, such as Elasticsearch, Fluentd, Logstash, and Kibana (EFK). Then, establish a data retention policy to periodically clean up old log data as needed.
4. Utilize a log cleaner: Some log collectors also offer a log cleaning function. You can configure a strategy to regularly delete outdated log data.

It is important to note that when cleaning up container logs, make sure it does not impact the functioning of the application.
