Rename the elasticsearch.yml file to elasticsearch.json inside config folder and add:

{
    "network" : {
        "host" : "10.0.0.4"
    }
}

Another option is to provide the settings externally either using the ES_JAVA_OPTS or as parameters to the elasticsearch command, for example:

$ elasticsearch -Des.network.host=10.0.0.4

Another option is to set es.default. prefix instead of es. prefix, which means the default setting will be used only if not explicitly set in the configuration file.

Another option is to use the ${...} notation within the configuration file which will resolve to an environment setting, for example:

{
    "network" : {
        "host" : "${ES_NET_HOST}"
    }
}

The location of the configuration file can be set externally using a system property:

$ elasticsearch -Des.config=/path/to/config/file
