Docker微服务-Jenkins+GitLab+Maven+Shell自动化构建实施案例
* 环境:
CentOS7
代码仓库:Gitlab
持续集成代码更新:Jenkins
构建打包:Maven
镜像自动交付脚本:Shell
* 创建基础持续集成项目-config
1.1 创建自由风格的软件项目-Job,创建config-tmp-release
1.2 创建maven项目-Job,创建基础项目config-tmp-ms
1.3 配置config-tmp-ms基础项目
基于jdk8,配置config-tmp-ms项目Git代码仓库源,并选取release分支。
配置关联项目config-tmp-release:
构建命令及构建后操作脚本:
1.4配置脚本
项目jar包同步脚本:/home/jenkins/docker-tmp/script/rsync.sh config-tmp-ms config-service
cat /home/jenkins/docker-tmp/script/rsync.sh #!/bin/bash ip=10.1.1.1 #docker tmp server passwd=****** rsync -vzrtopg --numeric-ids --progress --password-file=/etc/rsyncd.password6 /home/jenkins/.jenkins/workspace/$1/target/alaxiaoyou-$2-0.0.1-SNAPSHOT.jar root@$ip::$1 expect /home/jenkins/docker-test/script/image.exp $ip $passwd $1 $2 $3
其中config-tmp-ms必须跟项目job名称一样。$1为此项目job名称“config-tmp-ms”,$2为此项目代码[email protected]:xxx/alaxiaoyou-config-service.git, provider:config-service。目的是自动替换各个provider配置。
expect脚本远程触发rancher服务器上脚本: /home/jenkins/docker-pro/script/image.exp
cat /home/jenkins/docker-pro/script/image.exp #!/usr/bin/expect -f set ipaddress [lindex $argv 0] set passwd [lindex $argv 1] set msname [lindex $argv 2] set msnameb [lindex $argv 3] spawn ssh name@$ipaddress; expect "password:"; send "$passwd\r"; expect "#" send "sudo nohup /data/docker/layout-script/pro-all.sh $msname $msnameb >> /data/docker/logs/$msname.log &\r" expect eof {exit 1}
rancher server服务器上脚本,构建,推送push到阿里镜像仓库:/data/docker/layout-script/pro-all.sh

1.5 构建操作
构建config-tmp-release项目,此项目执行完成后,自动构建关联的下级项目config-tmp-ms,config-tmp-ms项目会Jenkins中自动拉取最新代码,触发rsync同步脚本,rsync脚本里触发docker镜像build和push操作。Jenkins最终构建完成后,即可将镜像仓库拉取最新交付的镜像。
* 创建基础持续集成项目-gateway
2.1 创建自由风格的软件项目-Job,创建gateway-tmp-release
2.2 创建maven项目-Job,创建基础项目gateway-tmp-ms
2.3 配置gateway-tmp-ms基础项目
基于jdk8,配置gateway-tmp-ms项目Git代码仓库源,并选取release分支。
配置关联项目gateway-tmp-release:
配置构建前操作脚本,构建命令,构建后操作脚本:
2.4配置脚本
构建前配置模板替换,配置成相应的provider,这里为gateway provider:
脚本:sh /home/jenkins/docker-tmp/script/configuration.sh gateway-tmp-ms api-gateway
cat /home/jenkins/docker-tmp/script/configuration.sh #!/bin/bash sed s/module/alaxiaoyou-$2/g /home/jenkins/.jenkins/workspace/ms-tmp-configuration/module.yml > /home/jenkins/.jenkins/workspace/ms-tmp-configuration/bootstrap.yml yes | cp -rfp /home/jenkins/.jenkins/workspace/ms-tmp-configuration/bootstrap.yml /home/jenkins/.jenkins/workspace/$1/src/main/resources/
其中gateway-tmp-ms必须跟项目job名称一样。$1为此项目job名称“gateway-tmp-ms”,$2为此项目代码[email protected]:xxx.git名称"api-gateway"。目的是自动替换各个provider配置,接下来后面各个provider自动替换。
模板文件:
cat /home/jenkins/.jenkins/workspace/ms-tmp-configuration/module.yml spring: application: name: module cloud: zookeeper: connect-string: zookeeper1:2181,zookeeper2:2181,zookeeper3:2181 config: uri: http://msconfig:20000
构建后配置,项目包(maven打包)同步脚本rsync,从git仓库服务器拉取代码打包后,包同步到docker-tmp服务器(rancher服务器)中:
项目jar包同步脚本:sh /home/jenkins/docker-tmp/script/rsync.sh gateway-tmp-ms api-gateway

* 创建持续集成项目-sms
3.1 创建maven项目-Job,创建sms-tmp-release
3.2 配置ms-tmp-release项目
基于jdk8,配置sms项目Git代码仓库源,并选取release分支。
构建基于pom.xml进行构建
3.3 创建maven项目-Job,创建sms-tmp-ms
3.4 配置sms-tmp-ms项目
基于jdk8,配置sms项目Git代码仓库源,并选取release分支:
配置关联项目sms-tmp-release:
配置构建前操作脚本,构建命令,构建后操作脚本:
3.5配置脚本
构建前配置模板替换,配置成相应的provider,这里为sms provider:
脚本:sh /home/jenkins/docker-tmp/script/configuration.sh sms-tmp-ms sms-provider
cat /home/jenkins/docker-tmp/script/configuration.sh sms-tmp-ms sms-provider #!/bin/bash sed s/module/alaxiaoyou-$2/g /home/jenkins/.jenkins/workspace/ms-tmp-configuration/module.yml > /home/jenkins/.jenkins/workspace/ms-tmp-configuration/bootstrap.yml yes | cp -rfp /home/jenkins/.jenkins/workspace/ms-tmp-configuration/bootstrap.yml /home/jenkins/.jenkins/workspace/$1/src/main/resources/

其中sms-tmp-ms必须跟项目job名称一样。$1为此项目job名称“sms-tmp-ms”,$2为此项目代码[email protected]:xxx.git名称"sms-provider"。目的是自动替换各个provider配置。
构建后配置,项目包(maven打包)同步脚本rsync,从git仓库服务器拉取代码打包后,包同步到docker-tmp服务器(rancher服务器)中:
脚本:sh /home/jenkins/docker-tmp/script/rsync.sh sms-tmp-ms sms-provider 256m

Jenkins和rancher不在同一台服务器行,用shell expect脚本远程触发rancher服务器上脚本:
cat /home/jenkins/docker-test/script/image.exp #!/usr/bin/expect -f set ipaddress [lindex $argv 0] set passwd [lindex $argv 1] set msname [lindex $argv 2] set msnameb [lindex $argv 3] set jvm [lindex $argv 4] spawn ssh name@$ipaddress; expect "password:"; send "$passwd\r"; expect "#" send "sudo nohup /data/docker/layout-script/all.sh $msname $msnameb $jvm >> /data/docker/logs/$msname.log &\r" expect eof {exit 1}

3.6 构建操作
构建sms-tmp-release项目,此项目执行完成后,自动构建关联的下级项目sms-tmp-ms,sms-tmp-ms项目会Jenkins中自动拉取最新代码,触发rsync同步脚本,rsync脚本里触发docker镜像build和push操作。Jenkins最终构建完成后,即可将镜像仓库拉取最新交付的镜像。
3.7 发布已构建镜像
进入rancher控制台
添加服务tmp-sms-ms:
映射卷:
点击“创建”,选中“创建前总是拉取镜像”,rancher便会分发任务至agent,进行最新镜像的拉取。
其中镜像为已在rancher宿主机上,进行手动镜像构建交付到阿里云镜像仓库的。并非通过Jenkins自动构建交付到阿里云镜像仓库。
3.8 镜像升级、回滚操作
升级步骤:
停止该服务正在运行的容器
拉取最新镜像
运行新容器
回滚:
如果不单击rancher控制台右上角“Upgraded”,该服务可进行回滚操作。
rancher控制台上方为“stopped”状态的容器为旧容器,单击“启动”按钮可进行回滚;
下方为“Running”状态的容器为升级的容器,单击右上角“Upgraded”按钮可进行回滚;容器镜像升级完成,旧容器销毁。
3.9 阿里云镜像仓库交付的镜像
说明:以上配置了两个基础服务容器的持续交付,一个常规服务容器的持续交付,其他的容器服务持续交付类似操作,这不做重复操作。其中,构建、推送镜像仓库的脚本里对应的IP配置为生产环境地址,由于此次测试环境为内网,无外网IP。所以,涉及到镜像的push操作无法操作成功。各个服务provider的打包,如要在Jenkins中自动操作,无法完成。所以,均从其他已打好包的服务器上拷贝过来,然后在rancher宿主机进行构建、推送push到阿里云镜像仓库。
