Can I ingest the logs from custom path from the container inside the Kubernetes cluster?

Yes, you can collect the logs from a local path in your Kubernetes cluster. Here is the section that you need to change in the values.yaml file:

rawConfig: |-
    @INCLUDE fluent-bit-service.conf
    [INPUT]
      Name             tail
      Path             /var/log/containers/*.log
      Multiline        On
      Parser_Firstline multi_line
      Tag              containers.*
      Refresh_Interval 1
      Rotate_Wait      60
      Mem_Buf_Limit    5MB
      Skip_Long_Lines  On
      DB               /tail-db/tail-containers-state.db
      DB.Sync          Normal

The "path" parameter above needs to be changed to that of your local file path.

Note: If you want to continue collecting the /var/log/containers/*.log logs, then a new [INPUT] section, like the one above, needs to be created for your local file path.
