NAME
docker-logs - Fetch the logs of a container
SYNOPSIS
docker logs [-f|--follow[=false]] [--help] [--since[=SINCE]] [-t|--timestamps[=false]] [--tail[="all"]] CONTAINER
DESCRIPTION
The docker logs command batch-retrieves whatever logs are present for a container at the time of execution. This does not guarantee execution order when combined with a docker run (i.e., your run may not have generated any logs at the time you execute docker logs).
The docker logs --follow command combines commands docker logs and docker attach. It will first return all logs from the beginning and then continue streaming new output from the container’s stdout and stderr.
Warning: This command works only for json-file logging driver.
OPTIONS
--help Print usage statement
-f, --follow=true|false Follow log output. The default is false.
--since="" Show logs since timestamp
-t, --timestamps=true|false Show timestamps. The default is false.
--tail="all" Output the specified number of lines at the end of logs (defaults to all logs)
The --since option shows only the container logs generated after
a given date. You can specify the date as an RFC 3339 date, a UNIX
timestamp, or a Go duration string (e.g. 1m30s, 3h). Docker computes
the date relative to the client machine’s time. You can combine
the --since option with either or both of the --follow or --tail options.
