     4  # NAME
     5  docker-logs - Fetch the logs of a container
     6  
     7  # SYNOPSIS
     8  **docker logs**
     9  [**-f**|**--follow**[=*false*]]
    10  [**--help**]
    11  [**--since**[=*SINCE*]]
    12  [**-t**|**--timestamps**[=*false*]]

    14  CONTAINER
    15  
    16  # DESCRIPTION
    17  The **docker logs** command batch-retrieves whatever logs are present for
    18  a container at the time of execution. This does not guarantee execution
    19  order when combined with a docker run (i.e., your run may not have generated
    20  any logs at the time you execute docker logs).
    21  
    22  The **docker logs --follow** command combines commands **docker logs** and
    23  **docker attach**. It will first return all logs from the beginning and
    24  then continue streaming new output from the container’s stdout and stderr.
    25  
    26  **Warning**: This command works only for **json-file** logging driver.
    27
