zombodb 默认对于es的连接是没有密码的，很不安全，可选的方式，基于nginx+basci auth
使用es 的X-Pack，使用amazon的opendistro 也是一个很不错的方案,以下是一个简单测试，同时
会有关于使用basic auth 模式的连接配置
注意，测试使用的pg zombodb docker 镜像使用zombodb 4.0 构建，会有es 兼容的问题，所以最好选择好opendistro 版本
环境准备
- docker-compose 文件
注意es 禁用了tls 的认证，使用了单机模式
version: "3"
services:
pg-zombodb:
image: dalongrong/pgspider:zombodb-plv8
ports:
- "5432:5432"
environment:
- "POSTGRES_PASSWORD=dalong"
elasticsearch:
image: amazon/opendistro-for-elasticsearch:0.10.0
ports:
- "9200:9200"
environment:
- "discovery.type=single-node"
- "http.host=0.0.0.0"
- "opendistro_security.ssl.http.enabled=false"
- "cluster.name=odfe-cluster"
- "transport.host=0.0.0.0"
- "network.host=0.0.0.0"
- "ES_JAVA_OPTS=-Xms512m -Xmx512m"
使用
- 启动服务
docker-compose up -d
- 启用扩展
CREATE EXTENSION zombodb;
// 创建表
CREATE TABLE products (
id SERIAL8 NOT NULL PRIMARY KEY,
name text NOT NULL,
keywords varchar(64)[],
short_summary text,
long_description zdb.fulltext,
price bigint,
inventory_count integer,
discontinued boolean default false,
availability_date date
);
// 添加索引，同时使用basic auth 模式连接es
CREATE INDEX idxproducts
ON products
USING zombodb ((products.*))
WITH (url='http://admin:admin@elasticsearch:9200/');
- 添加测试数据
INSERT INTO "public"."products"("id","name","keywords","short_summary","long_description","price","inventory_count","discontinued","availability_date")
VALUES
(1,E'Magical Widget',E'{magical,widget,round}',E'A widget that is quite magical',E'Magical Widgets come from the land of Magicville and are capable of things you can\'t imagine',9900,42,FALSE,E'2015-08-31'),
(2,E'Baseball',E'{baseball,sports,round}',E'It\'s a baseball',E'Throw it at a person with a big wooden stick and hope they don\'t hit it',1249,2,FALSE,E'2015-08-21'),
(3,E'Telephone',E'{communication,primitive,"alexander graham bell"}',E'A device to enable long-distance communications',E'Use this to call your friends and family and be annoyed by telemarketers. Long-distance charges may apply',1899,200,FALSE,E'2015-08-11'),
(4,E'Box',E'{wooden,box,"negative space",square}',E'rong',E'A wooden container that will eventually rot away. Put stuff it in (but not a cat).',17000,0,TRUE,E'2015-07-01');
- 查询
select * from products WHERE products ==> 'rong';
效果 
说明
amazon的opendistro 是一个很不错的es 替代，功能强大，安全性以及周边也都很不错，加上zombodb真的很不错
