     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*]]
    13  [**--tail**[=*"all"*]]
    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 the **json-file** or **journald**
    27  logging drivers.
    28  
    29  # OPTIONS
    30  **--help**
    31    Print usage statement
    32  
    33  **-f**, **--follow**=*true*|*false*
    34     Follow log output. The default is *false*.
    35  
    36  **--since**=""
    37     Show logs since timestamp
    38  
    39  **-t**, **--timestamps**=*true*|*false*
    40     Show timestamps. The default is *false*.
    41  
    42  **--tail**="all"
    43     Output the specified number of lines at the end of logs (defaults to all logs)
    44  
    45  The `--since` option shows only the container logs generated after
    46  a given date. You can specify the date as an RFC 3339 date, a UNIX
    47  timestamp, or a Go duration string (e.g. `1m30s`, `3h`). Docker computes
    48  the date relative to the client machine’s time. You can combine
    49  the `--since` option with either or both of the `--follow` or `--tail` options.
