pgspider griddb 试用

前边有构建一个简单的pgspider griddb fdw 的docker 镜像，以下是一个简单的试用

一些说明

关于pgspider griddb fdw 的构建目前4.3 有bug，使用的是4.2版本的，同时对于java 链接使用member ip，不是广播地址ip

环境准备

• griddb

  自己调整的一些参数

start_griddb.sh 文件

#!/bin/bash

​

chown gsadm.gridstore /var/lib/gridstore/data

IP=`grep $HOSTNAME /etc/hosts | awk ' { print $1 }'`

dokerfile

 

 

 

 

 

FROM griddbnet/griddb

COPY start_griddb.sh /start_griddb.sh

• griddb java 镜像
  代码在项目目录下，参考链接的github 地址
  dockerfile

 

FROM openjdk:8u242-jdk-stretch

WORKDIR /app

COPY griddb-app.jar /app/griddb-app.jar

COPY entrypoint.sh /entrypoint.sh

ENTRYPOINT [ "/entrypoint.sh" ]

java -jar /app/griddb-app.jar $MEMBER

• docker-compose 文件

version: "3"

services: 

  pgspider-griddb:

    image: dalongrong/pgspider:griddb-4.2

    environment: 

    - "POSTGRES_PASSWORD=dalong"

    ports: 

    - "5432:5432"

    - "10050:10050"

    - "10080:10080"

    - "20001:20001"

使用

• 构建镜像

docker-compose  build

• 启动griddb 以及pgspider griddb fdw

docker-compose up -d griddb pgspider-griddb

• 导入数据

  通过java 应用导入数据

docker-compose up griddb-java

• 扩展使用

CREATE EXTENSION griddb_fdw;

CREATE SERVER griddb_svr FOREIGN DATA WRAPPER griddb_fdw OPTIONS(notification_member 'griddb:10001',clustername 'defaultCluster');

CREATE USER MAPPING FOR public SERVER griddb_svr OPTIONS(username 'admin', password 'admin');

IMPORT FOREIGN SCHEMA griddb_schema FROM SERVER griddb_svr INTO public;

select * from col01;

• 效果

 

 

说明

以上就是对于已经构建好的docker 镜像的简单使用，后边可以好好系统学习下griddb，一个很不错的面向iot 以及时序数据的系统
