1. 首先拉镜像，推荐使用阿里云的镜像加速，毕竟不是都有vpn，执行 docker pull elasticsearch:6.4.0，我这儿使用的是6.4.0，按需可修改。

dailong-MacBook-Pro:~ dailong$ docker pull elasticsearch:6.4.0
6.4.0: Pulling from library/elasticsearch

Status: Downloaded newer image for elasticsearch:6.4.0
docker.io/library/elasticsearch:6.4.0

2. 查看镜像：

dailong-MacBook-Pro:~ dailong$ docker images
REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE
elasticsearch        6.4.0               1ac676545731        16 months ago       791MB

3. 运行镜像：需要注意用程序连接 需要暴露9300端口，否则程序会报连接失败

dailong-MacBook-Pro:~ dailong$ docker run -d -p 9200:9200 -p 9300:9300 --name="elasticsearch" elasticsearch:6.4.0
7fcb25eb80fd538df74d2aaad9059fd72d9c9a6eb416fc7a347fa647b80c4aa2

4. 查看运行镜像:

dailong-MacBook-Pro:~ dailong$ docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                              NAMES
7fcb25eb80fd        elasticsearch:6.4.0   "/usr/local/bin/dock…"   7 seconds ago       Up 6 seconds        0.0.0.0:9200->9200/tcp, 9300/tcp   elasticsearch
dailong-MacBook-Pro:~ dailong$ cd /work/elasticsearch

安装head插件，主要是为了方便调试

• 拉取镜像:

dailong-MacBook-Pro:elasticsearch dailong$ docker pull mobz/elasticsearch-head:5

• 创建容器：

dailong-MacBook-Pro:elasticsearch dailong$ docker create --name elasticsearch-head -p 9100:9100 mobz/elasticsearch-head:5
e0b064466f206c159eee458c35546dd4e2031e369cafea6a59848915f93eeef5

• 启动容器:

dailong-MacBook-Pro:elasticsearch dailong$ docker start elasticsearch-head
elasticsearch-head

• 查看head http://localhost:9100/

问题

集群未连接

如上图显示，集群未连接，按照网上说的有跨域问题，需进入docker镜像，修改docker中elasticsearch的elasticsearch.yml文件。
在文件最后加上

http.cors.enabled: true 
http.cors.allow-origin: "*"

如下

dailong-MacBook-Pro:elasticsearch dailong$ docker exec -it elasticsearch /bin/bash
[root@7fcb25eb80fd elasticsearch]# vi config/elasticsearch.yml
[root@7fcb25eb80fd elasticsearch]# cat config/elasticsearch.yml
cluster.name: "docker-cluster"
network.host: 0.0.0.0

# minimum_master_nodes need to be explicitly set when bound on a public IP
# set to 1 to allow single node clusters
# Details: https://github.com/elastic/elasticsearch/pull/17288
discovery.zen.minimum_master_nodes: 1

http.cors.enabled: true 
http.cors.allow-origin: "*"
[root@7fcb25eb80fd elasticsearch]# exit
exit

退出镜像，并重启服务：

dailong-MacBook-Pro:elasticsearch dailong$ docker restart elasticsearch
elasticsearch
dailong-MacBook-Pro:elasticsearch dailong$ docker ps
CONTAINER ID        IMAGE                       COMMAND                  CREATED             STATUS              PORTS                              NAMES

数据浏览 f12后台错误

参考连接：https://blog.csdn.net/A_Story_Donkey/article/details/84135475

docker exec -it elasticsearch-head /bin/bash #进入es_head插件安装目录终端

head镜像无法使用vim,需要做一下操作：

apt update
apt-get install -y vim

修改vendor.js (/usr/src/app/_site/vendor.js),然后退出，重启

1. 6886行 /contentType: "application/x-www-form-urlencoded 
    改成 contentType: "application/json;charset=UTF-8" 
2. 7574行 var inspectData = s.contentType === "application/x-www-form-urlencoded" && 
    改成 var inspectData = s.contentType === "application/json;charset=UTF-8" &&

docker restart elasticsearch-head

效果：
