I'm trying to get started with follow [Install Elasticsearch with Docker | Elasticsearch Reference [6.0] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html), and even though I set initial password with Docker environment variable _ELASTIC\_PASSWORD_ and as I start it, I noticed following in logs:

> elasticsearch | [2017-12-02T03:42:55,095][INFO][o.e.x.s.a.AuthenticationService] [770ea4c1e78f] Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]

however, I keep seeing failed attempts of authentication (not mine) as I'm able to login without any issues:

```
# curl -I http://elastic:MagicWord@0:9200
HTTP/1.1 200 OK
content-type: application/json; charset=UTF-8
content-length: 431

# 

```

Please advise.

Are you running Kibana, Logstash, Beats, or anything else that is trying to connect to your Elasticsearch?
