       docker-container-logs - Fetch the logs of a container


       docker container logs [OPTIONS] CONTAINER


       The docker container 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 container logs).

       The docker container logs --follow command combines commands docker container 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 the json-file or journald logging drivers.

       The --since and --until options can be Unix timestamps, date formatted timestamps, or Go
       duration strings (e.g. 10m, 1h30m) computed relative to the client machine's time.
       Supported formats for date formatted time stamps include RFC3339Nano, RFC3339,
       2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00, and 2006-01-02. The
       local timezone on the client will be used if you do not provide either a Z or a +-00:00
       timezone offset at the end of the timestamp.  When providing Unix timestamps enter
       seconds[.nanoseconds], where seconds is the number of seconds that have elapsed since
       January 1, 1970 (midnight UTC/GMT), not counting leap  seconds (aka Unix epoch or Unix
       time), and the optional .nanoseconds field is a fraction of a second no more than nine
       digits long. You can combine the --since or --until options with either or both of the
       --follow or --tail options.

       The docker container logs --details command will add on extra attributes, such as
       environment variables and labels, provided to --log-opt when creating the container.

       In order to retrieve logs before a specific point in time, run:

              $ docker run --name test -d busybox sh -c "while true; do $(echo date); sleep 1; done"
              $ date
              Tue 14 Nov 2017 16:40:00 CET
              $ docker logs -f --until=2s
              Tue 14 Nov 2017 16:40:00 CET
              Tue 14 Nov 2017 16:40:01 CET

           Number of lines to show from the end of the logs

       -t, --timestamps[=false]
