I'm trying to get started with follow Install Elasticsearch with Docker | Elasticsearch Reference [6.0] | Elastic, 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.
