# NAME
|
|
docker-logs - Fetch the logs of a container
|
|
|
|
# SYNOPSIS
|
|
**docker logs**
|
|
[**-f**|**--follow**]
|
|
[**--help**]
|
|
[**--since**[=*SINCE*]]
|
|
[**-t**|**--timestamps**]
|
|
[**--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 the **json-file** or **journald**
|
|
logging drivers.
|
|
|
|
# OPTIONS
|
|
**--help**
|
|
Print usage statement
|
|
|
|
**--details**=*true*|*false*
|
|
Show extra details provided to logs
|
|
|
|
**-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 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.
