How to run Elasticsearch 5.2.1 as root user in docker

I am working on a Django project which uses elasticsearch.The Django version is 1.9.2,python version is 2.7. I'm deploying project inside of a Docker container, which usually run processes as root user.The image is successfuly built and everything works fine except elasticsearch. I get 

root@05641a637072:~/arches# elasticsearch-5.2.1/bin/elasticsearch
[2017-04-19T07:37:13,347][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [] uncaught exception in thread [main]

error when trying to start ElasticSearch, and there doesn't seem to be a way to get around it. What's the reason ElasticSearch can't run as root? Inside of the docker container things are isolated and root processes are considered safe.

It’s not recommended to run elasticsearch as root. For temporary solution, you can run by enabling property es.insecure.allow.root as line below.

bin/elasticsearch -Des.insecure.allow.root=true
