Docker+Jenkins实现spring-boot项目持续集成

1. Jenkins配置-源码
   
2. Jenkins配置-构建触发器
   
3. Jenkins配置-构建环境
   
   构建前，从集中存放配置文件的GitLab中拉取最新配置文件，包含Dockerfile，后面开始构建会引用最新文件。

   cd /data/httpd/release/b2b-configuration;git pull
   sleep 3;
   yes | cp -rfp  /data/httpd/release/b2b-configuration/Spring-partner/QA/application.yml  /home/jenkins/.jenkins/workspace/b2b-partner-test/src/main/resources/
   yes | cp -rfp  /data/httpd/release/b2b-configuration/Spring-partner/QA/Dockerfile  /home/jenkins/.jenkins/workspace/b2b-partner-test/

4. Jenkins配置-构建和构建后操作
   
   先同步jar包和Dockerfile到Docker那台server上，然后用expect交互命令将shell脚本发送到Docker那台server上，进行docker容器的构建、启动、push到阿里云镜像仓库等操作。
   Jenkins这台server的rsync脚本：bash /home/jenkins/docker-test/script/b2b-rsync.sh b2b-partner-test 后带参数。
   rsync同步脚本：

   #!/bin/bash
   IP=10.10.10.10
   [email protected]
   echo -e "开始同步jar包..."
   rsync -vzrtopg --numeric-ids --progress --password-file=/etc/rsyncd.password6 /home/jenkins/.jenkins/workspace/$1/target/b2b-partner.jar [email protected]$IP::$1
   echo -e "开始同步Dockerfile..."
   rsync -vzrtopg --numeric-ids --progress --password-file=/etc/rsyncd.password6 /home/jenkins/.jenkins/workspace/$1/Dockerfile [email protected]$IP::$1
   expect /home/jenkins/docker-test/script/image_b2b.exp $IP $PASSWD $1

   expect交互命令脚本：/home/jenkins/docker-test/script/image_b2b.exp

   #!/usr/bin/expect -f
   set ipaddress [lindex $argv 0]
   set passwd [lindex $argv 1]
   set jobname [lindex $argv 2]
   spawn ssh [email protected]$ipaddress;
   expect "password:";
   send "$passwd\r";
   expect "#"
   send "sudo nohup /data/docker/layout-script/docker-qa.sh $jobname  >> /data/docker/logs/$jobname.log &\r"

   注意：执行上面expect脚本前，需将ssh的用户，到对方server的visudo配置中加入：xiaoyu ALL=(ALL) NOPASSWD: ALL， 要不然用户无法ssh过去。

• Docker配置
  查看同步到Docker的Dockerfile，maven构建好的jar包也同步到此目录下。

  scp [email protected]:~/.jenkins/workspace/$1/Dockerfile $JOBREPO
  echo -e "\n[$JOBMS]" >> /etc/rsyncd.conf
  echo "path=/data/docker/$JOBMS/" >> /etc/rsyncd.conf
  echo "comment = update

  gid = root
  secrets file = /etc/rsyncd.secrets" >> /etc/rsyncd.conf
  else
  echo -e "\n时间$DTIME，开始构建job-docker镜像"
  fi
  cd $JOBREPO
  docker build -t ms-b2b/$JOBMS .
  if [ $? -ne 0 ];then
  echo -e "时间$DTIME，$JOBMS 镜像构建失败，请检查dockerfile !"
  exit
  else
  echo -e "时间$DTIME，开始删除之前job-Docker容器."
  docker rm $CONTAINER_NAME -f
  echo -e "时间$DTIME，开始运行job-Docker容器."
  docker run --name $CONTAINER_NAME -v $JOBREPO:$JOBREPO -d -p 8081:8081 ms-b2b/$JOBMS
  sleep 5
  echo -e "时间$DTIME，$CONTAINER_NAME容器创建完成.开始推送到阿里镜像仓库中..."
  IMAGEID=`docker images |grep "ms-b2b/$JOBMS" |awk ‘{print $3}‘`
  echo "Image镜像ID：$IMAGEID"
  CONTAINERID=`docker images |grep "ms-b2b/$JOBMS" |awk ‘{print $1}‘`
  echo "Container容器：$CONTAINERID"
  docker login --username=username --password=PASSWD registry.cn-hangzhou.aliyuncs.com
  docker tag $IMAGEID registry.cn-hangzhou.aliyuncs.com/$IMGREPO/$IMGNAME:$VERSION
