In order to rotate pod logs, logrotate pod is used in kubernetes. By default, logrotate will use copytruncate mode to create a new rotated file, however datadog cannot work well in this mode, failed to retrieve pod log occasionally.

So I try to set the mode to create 0644 root root, but the following error comes up

Cross-device link

And logrotate failed to rotate logs either.

Could someone help me to resolve this issue or is there any better practice on rotate pod logs?
