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 }'`

- 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" ]
entrypoint.sh
#!/bin/sh
MEMBER=$MEMBER_ADDR
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"
griddb-java:
build:
context: ./
dockerfile: ./Dockerfile-java
environment:
- "MEMBER_ADDR=griddb:10001"
griddb:
build: ./
volumes:
- "./log:/var/lib/gridstore/log"
ports:
- "10001:10001"
- "10010:10010"
- "10020:10020"
- "10030:10030"
- "10040:10040"
- "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
