+You need a folder named `config` with your own version of `elasticsearch.yml`. You can add other Elasticserach configuration files to this folder, such as `logging.yml`.

+docker run --rm -v /path/to/config:/elasticsearch/config quay.io/pires/docker-elasticsearch-kubernetes:1.5.2

+
+In case you want to specify a data folder so that Elasticsearch writes to storage outside the container, run
+```
+docker run --rm -v /path/to/config:/elasticsearch/config -v /path/to/data_folder:/data quay.io/pires/docker-elasticsearch-kubernetes:1.5.2
+```
