docker安装es

1.下载镜像
es:
docker pull docker.elastic.co/elasticsearch/elasticsearch:6.3.2
es界面：
docker pull mobz/elasticsearch-head:5

2.启动容器：
docker run -d --name es -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:6.3.2
docker run -d --name es_admin -p 9100:9100 mobz/elasticsearch-head:5
3.修改参数：
3.1 es跨域参数：
[root@qixin conf.d]# docker exec -it es /bin/bash
[root@f057fcd3b00a elasticsearch]# cd config/
[root@f057fcd3b00a config]# cat elasticsearch.yml
添加：
http.cors.enabled: true
http.cors.allow-origin: "*"
重启es容器：
[root@qixin conf.d]# docker restart es
3.2 es页面外部访问：
[root@qixin conf.d]# docker exec -it es_admin bash
[root@qixin conf.d]# docker cp es_admin:/usr/src/app/Gruntfile.js .
修改配置，添加hostname：
connect: {
    server: {
        options: {
            hostname: '0.0.0.0',
            port: 9100,
            base: '.',
            keepalive: true
        }
    }
}
替换配置：
docker1.8：docker cp Gruntfile.js es_admin:/usr/src/app/
docker1.7 docker cp 会报错Error: Path not specified
方法如下:
[root@qixin conf.d]# docker ps|grep elasticsearch-head
7a15021e618a        mobz/elasticsearch-head:5                             "/bin/sh -c 'grunt s   28 minutes ago      Up 19 minutes       0.0.0.0:9100->9100/tcp                             es_admin     
[root@qixin ~]# docker inspect -f '{{.Id}}' c508617918df
[root@qixin ~]# cp Gruntfile.js /var/lib/docker/devicemapper/mnt/7a15021e618ab0a4409ab342ee265b0ae192e5a5056951b82337df55a3ddb3d6/rootfs/usr/src/app/
docker restart es_admin

3.3 也可以通过nginx转发：

nginx配置：
server {
    listen      9111;
    server_name  localhost;
    charset     utf-8;

    client_max_body_size 75M;   # adjust to taste

    location / {
        proxy_pass http://localhost:9100;
    }
}

server {
    listen      9222;
    server_name  localhost;
    charset     utf-8;
    
    client_max_body_size 75M;   # adjust to taste
    
    location / {
        proxy_pass http://localhost:9200;
    }
}
