Elasticsearch version update

[GeryNi]

The version of Elasticsearch mentioned in the documentation (see: ) references docker.elastic.co/elasticsearch/elasticsearch:6.6.0

However SpringBoot 2.4.6 relies on Spring 5.3.7, which requires Elasticserach version 7.17.3:

• https://docs.spring.io/spring-data/elasticsearch/reference/elasticsearch/versions.html

Could update the recoomandations listed in the documentation?

Kind regards,
Géry.

Using Elastic version 6.6.0 resulted in the following exception:

Caused by: org.elasticsearch.client.ResponseException: method [PUT], host [http://localhost:9200], URI [/_template/landsat-8-l1-template?master_timeout=30s&include_type_name=true], status line [HTTP/1.1 400 Bad Request]
