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

# SYNOPSIS
**docker logs**
[**-f**|**--follow**[=*false*]]
[**--help**]
[**-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.
