    12  # Splunk logging driver
    13  
    14  The `splunk` logging driver sends container logs to
    15  [HTTP Event Collector](http://dev.splunk.com/view/event-collector/SP-CAAAE6M)
    16  in Splunk Enterprise and Splunk Cloud.
    17  
    18  ## Usage
    19  
    20  You can configure the default logging driver by passing the `--log-driver`
    21  option to the Docker daemon:
    22  
    23      docker daemon --log-driver=splunk
    24  
    25  You can set the logging driver for a specific container by using the
    26  `--log-driver` option to `docker run`:
    27  
    28      docker run --log-driver=splunk ...
    29  
    30  ## Splunk options
    31  
    32  You can use the `--log-opt NAME=VALUE` flag to specify these additional Splunk
    33  logging driver options:
    34

    38  | `splunk-url`                | required | Path to your Splunk Enterprise or Splunk Cloud instance (including port and schema used by HTTP Event Collector) `https://your_splunk_instance:8088`.                                                              |

    46  | `labels`                    | optional | Comma-separated list of keys of labels, which should be included in message, if these labels are specified for container.                                                                                          |

    48  
    49  If there is collision between `label` and `env` keys, the value of the `env` takes precedence.
    50  Both options add additional fields to the attributes of a logging message.
    51  
    52  Below is an example of the logging option specified for the Splunk Enterprise
    53  instance. The instance is installed locally on the same machine on which the
    54  Docker daemon is running. The path to the root certificate and Common Name is
    55  specified using an HTTPS schema. This is used for verification.
    56  The `SplunkServerDefaultCert` is automatically generated by Splunk certificates.
    57  
    58      docker run --log-driver=splunk \
    59          --log-opt splunk-token=176FCEBF-4CF5-4EDF-91BC-703796522D20 \
    60          --log-opt splunk-url=https://splunkhost:8088 \
    61          --log-opt splunk-capath=/path/to/cert/cacert.pem \
    62          --log-opt splunk-caname=SplunkServerDefaultCert
    63          --log-opt tag="{{.Name}}/{{.FullID}}"
    64          --log-opt labels=location
    65          --log-opt env=TEST
    66          --env "TEST=false"
