Docker – the default user and password for elasticsearch

authenticationcredentialsdockerelasticsearch

I have installed Elastic with Docker:

docker run -p 9200:9200 \
           -p 9300:9300 \
           -e "discovery.type=single-node" \ 
           docker.elastic.co/elasticsearch/elasticsearch:5.6.2

But curl localhost:9200 fails with authentication error:

{
  "error": {
    "root_cause": [
      {
        "type": "security_exception",
        "reason": "missing authentication token for REST request [/]",
        "header": {
          "WWW-Authenticate": "Basic realm=\"security\" charset=\"UTF-8\""
        }
      }
    ],
    "type": "security_exception",
    "reason": "missing authentication token for REST request [/]",
    "header": {
      "WWW-Authenticate": "Basic realm=\"security\" charset=\"UTF-8\""
    }
  },
  "status": 401
}

What is the default username/password combo for Elasticsearch?

Best Answer

Defaults are:

user: elastic
password: changeme

So:

$ curl -u elastic:changeme localhost:9200
{
  "name" : "5aEHJ-Y",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "3FmaYN7rS56oBTqWOyxmKA",
  "version" : {
    "number" : "5.6.2",
    "build_hash" : "57e20f3",
    "build_date" : "2017-09-23T13:16:45.703Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.1"
  },
  "tagline" : "You Know, for Search"
}
