我在docker上安裝的elasticsearch是latest，也就是最高版。
下面的6.2.2是我後安的。
項目中引用的spring-data-elasticsearch是3.1.5.RELEASE版的。
在的github地址上：https://github.com/spring-projects/spring-data-elasticsearch，由如下說明：
說明，我們使用的elasticsearch是6.2.2版本。
關鍵是在docker hub elasticsearch上並沒有6.2.2版，或者相鄰的版本。
所以我們上elasticsearch官網上下載，直接在docker中下載鏡像：
docker pull docker.elastic.co/elasticsearch/elasticsearch:6.2.2
運行
docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:6.2.4
發現，運行了，馬上就停止了。報以下錯誤：

在elasticsearch6.2的docker安裝頁面上，地址：https://www.elastic.co/guide/en/elasticsearch/reference/6.2/docker.html，由如下說明：
The vm.max_map_count setting should be set permanently in /etc/sysctl.conf: $ grep vm.max_map_count /etc/sysctl.conf vm.max_map_count=262144 To apply the setting on a live system type: sysctl -w vm.max_map_count=262144
我們設定vm.max_map_count的值>262144即可。
在重啟，??。
註意的是，在配置文件中，配置
data:
elasticsearch:
cluster-name: docker-cluster
不是最新版的：elasticsearch
