## 開啟鏡像并映射端口9200和9300(ElasticSearch的默認端口為9200)
```
root@ubuntu:/home/guanfuchang# docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -d elasticsearch:6.5.1
680a68077527e76a00391ec9e5ac311c259eb81369e645b60c2f6982dfe951f3
```
```
root@ubuntu:/home/guanfuchang# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

```
>[info]9300是tcp通訊端口，集群間和TCPClient都走的它;
9200是http協議的RESTful接口，后續的API接口測試都是走的它。
## 測試服務是否正常
```
root@ubuntu:/home/guanfuchang# curl 127.0.0.1:9200
