如何在docker基础上使用sh脚本实现项目部署

• 前提须知:要安装docker和docker-compose才行,具体参考可跳转至如何安装和使用docker和如何安装和使用docker-compose

Linux目录架构演示

• 以下每个文件夹对应一个微服务项目,以api文件夹为例演示
• 以下.yml文件为docker-compose的对应配置文件, 主要目的是在不需要重新编译jar包,不需要重新打包jar的情况下 重启服务而用(不需要更新新版本情况下,机子崩了,项目都停了,要重新启动项目)
• 以下.sh文件是脚本部署文件,主要用于代码更新后新打包的jar包 去发布部署上线(代码更新了新功能,发布新版本,要置换掉原来jar包后才使用该脚本)
  
• 演示api微服务项目的对应的文件夹
  

docker-compose脚本

• 以下的app.yml和service.yml性质是一样的,只是因为演示的项目构造的原因分成2个文件而已(参考其中一个就行),用于启动微服务项目
• 以下的env.yml用于启动一些中间件配置服务的启动(比如nginx那些)
• 让现有的镜像变成容器跑起来

启动具体某个微服务

• 在docker-compose的yml配置文件的当前目录下输入以下命令 即可指定启动配置文件中某个项目
• 这里是启动docker-compose-service.yml配置文件里 配置的api微服务

docker-compose -f docker-compose-service.yml up -d xk-api

具体微服务jar包对应目录的配置脚本(重点)

• 以下演示微服务为api
• 将自己微服务项目的jar包,放在当前目录下即可

xk-api.sh(启动微服务项目,常用)

• 输入命令到当前目录下, 直接输入./xk-api.sh 即可直接将当前目录下的jar包变成docker方式启动
• 使jar包变成镜像,然后将镜像变成容器跑起来

#!/usr/bin/env bash
app_name='xk-api'
docker build -t xk/${app_name}:1.0-SNAPSHOT .
docker stop ${app_name}
echo '----stop container----'
docker rm ${app_name}
echo '----rm container----'
docker rmi `docker images | grep none | awk '{print $3}'`
echo '----rm none images----'
docker run -p 7778:7778 --name ${app_name} \
--link nacos-registry:nacos-registry \
--link elasticsearch:es \
--link logstash:logstash \
--network xk_default \
-e TZ="Asia/Shanghai" \
-v /etc/localtime:/etc/localtime \
-v /data/logs/${app_name}:/logs/xk-practice-api \
-v /data/act_file/inventory:/data/act_file/inventory \
-v /data/act_file/plan:/data/act_file/plan \
-d xk/${app_name}:1.0-SNAPSHOT
echo '----start container----'

xk-publish.sh(更新启动所有微服务)

• 这里演示的是启动所有微服务项目跑起来,除了admin和portal的微服务项目

#!/usr/bin/env sh
for file in ./*
do
  if [ -d $file ]
   then
     if [ $file == './admin' ] ||[ $file == './portal' ]
      then
         echo $file '当前服务需要在auth 服务启动后再启动，请手动执行'
      else
        cd $file
        sh *.sh
        cd ../
     fi
  fi
done
