How to View and Follow Docker Container Logs in Real Time
Inspect stdout and stderr output from containers with timestamps, tail line limits, and live streaming.
docker logs -f --tail 100 <container-name>Step-by-Step Execution Guide
docker logs -f <container-name>Continuously outputs incoming log lines until you press Ctrl+C.
docker logs -f --tail 100 <container-name>Prevents terminal buffer flooding by displaying only the latest 100 entries before tailing.
docker logs -t --tail 50 <container-name>Prepends each log line with an ISO 8601 UTC timestamp.
docker logs --since 30m <container-name>Filters logs produced within the last 30 minutes (supports 10m, 2h, or ISO dates).
