logs
Usage: docker logs [OPTIONS] CONTAINER
Fetch the logs of a container
Options:
--details Show extra details provided to logs
-f, --follow Follow log output
--help Print usage
--since string Show logs since timestamp (e.g. 2013-01-02T13:23:37) or relative (e.g. 42m for 42 minutes)
--tail string Number of lines to show from the end of the logs (default "all")
-t, --timestamps Show timestamps
Description
The docker logs
command batch-retrieves logs present at the time of execution.
Note
: this command is only functional for containers that are started with the
json-file
orjournald
logging driver.
For more information about selecting and configuring logging drivers, refer to Configure logging drivers.
The docker logs --follow
command will continue streaming the new output from
the container's STDOUT
and STDERR
.
Passing a negative number or a non-integer to --tail
is invalid and the
value is set to all
in that case.
The docker logs --timestamps
command will add an RFC3339Nano timestamp
, for example 2014-09-16T06:17:46.000000000Z
, to each
log entry. To ensure that the timestamps are aligned the
nano-second part of the timestamp will be padded with zero when necessary.
The docker logs --details
command will add on extra attributes, such as
environment variables and labels, provided to --log-opt
when creating the
container.
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
). Besides RFC3339 date
format you may also use RFC3339Nano, 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.
