Why didn't write logs to stdout and scrape container log files by fluentbit/prom...

I do, but with a different log aggregator (vector.dev), there are three reasons:

1. the log aggregator doesn't exactly support DNS lookups

2. You have to parse the log first, exactly precisely where the IP part, then do a proper lookup. But sometimes the log is just a mess.

3. where the log aggregator located cannot do host lookup because of different network and different DNS server.

So overall the lookup would better be done locally.
