docker-logs - Fetch the logs of a container
docker logs [-f|--follow] [--help] [--since[=SINCE]] [-t|--timestamps] [--tail[="all"]] CONTAINER
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 the json-file or journald logging drivers.
Show extra details provided to logs
Follow log output. The default is
Show logs since timestamp
Show timestamps. The default is
Output the specified number of lines at the end of logs
The --since option 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 option with either or both of the --follow or --tail options.
The docker logs --details command will add on extra attributes, such as environment variables and labels, provided to --log-opt when creating the container.
