数据网关docker-compose简介

一、背景

docker-compose适合单节点开发应用部署，部署方式简单、便捷。基础知识点参考文档《Docker基本应用说明v0.3.md》。其中官方文档说明：https://docs.docker.com/storage/volumes/

二、docker-compose管理容器

2.1创建映射目录

[root@xiangys0134-haddop01 data]# mkdir datagw/datagw_frame/profile -p
[root@xiangys0134-haddop01 data]# cd datagw/

2.2从容器中拷贝文件

[root@xiangys0134-haddop01 ~]# docker run -it registry.cn-hangzhou.aliyuncs.com/xunceprivate/public:datagw-v1.0.2 bash
#在另外一个shell窗口下执行
[root@xiangys0134-haddop01 ~]# name=(docker ps |grep datagw-v1.0.2|tail -1|awk '{print1}')
#拷贝配置文件目录，第一次运行docker-compose编排拷贝，后续直接修改配置文件即可
[root@xiangys0134-haddop01 datagw]# docker cp  name:/etc/uvframe ./frame/profile
#拷贝数据库脚本，每次执行都需要拷贝一次
[root@xiangys0134-haddop01 datagw]# if [ -d script ]; then rm -rf script ; fi ;docker cpname:/data/DataGW/script .
#权限设置
[root@xiangys0134-haddop01 datagw]# chown -R datagw. frame/

2.3配置文件说明

通过hostpath文件映射至容器文件模式，本地修改frame目录下的配置文件即可

2.4docker-compose编排

[root@xiangys0134-haddop01 datagw]# vi docker-compose.yml
version: '3'
services:
  datagw:
    image: registry.cn-hangzhou.aliyuncs.com/xunceprivate/public:datagw-v1.0.2
    container_name: datagw
    ports:
      - 12000:11000
      - 12001:11000
    volumes:
      - ./frame/profile:/home/frame/profile
    privileged: true
    #restart: always
    networks:
      - xunce

networks:
  xunce:

2.5启动容器

[root@xiangys0134-haddop01 datagw]# docker-compose up -d
[root@xiangys0134-haddop01 datagw]# docker-compose ps
 Name       Command       State                         Ports                      
-----------------------------------------------------------------------------------
datagw   /usr/sbin/init   Up      0.0.0.0:12001->11000/tcp,0.0.0.0:12000->11000/tcp

2.6docke-compose编排多个容器

略

三、数据库执行脚本

将script目录下sql脚本在数据库中运行

四、附

4.1数据网关和dc模块

version: '3'
services:
  datagw:
    image: registry.cn-hangzhou.aliyuncs.com/xunceprivate/public:datagw-v1.0.2

    ports:

    #privileged: true
    #restart: always
    networks:

  dc:

    container_name: dc
