     4  # NAME
     5  docker-logs - Fetch the logs of a container
     6  
     7  # SYNOPSIS
     8  **docker logs**
     9  [**-f**|**--follow**[=*false*]]
    10  [**--help**]
    11  [**-t**|**--timestamps**[=*false*]]
    12  [**--tail**[=*"all"*]]
    13  CONTAINER
    14  
    15  # DESCRIPTION
    16  The **docker logs** command batch-retrieves whatever logs are present for
    17  a container at the time of execution. This does not guarantee execution
    18  order when combined with a docker run (i.e., your run may not have generated
    19  any logs at the time you execute docker logs).
    20  
    21  The **docker logs --follow** command combines commands **docker logs** and
    22  **docker attach**. It will first return all logs from the beginning and
    23  then continue streaming new output from the container’s stdout and stderr.
    24  
    25  **Warning**: This command works only for **json-file** logging driver.
    26
