Explain Docker logging strategies and log management.

Docker logging strategies for production environments: 1) Logging drivers: json-file (default), syslog, fluentd with docker run --log-driver options, 2) Configure in daemon.json with log-driver and log-opts for max-size and max-file, 3) Centralized logging with ELK: app with fluentd logging driver, fluentd service for log processing, 4) Application logging best practices: Structured logging with JSON format, Include correlation IDs, timestamps, user context, 5) Log aggregation patterns: Sidecar containers for log processing, Log shipping to external systems, Real-time log streaming, Log retention policies, 6) Monitoring: docker logs -f --tail 100 container, docker logs container | grep ERROR | wc -l.
