使用docker slave 发布dubbo应用

1、部署好docker slave后，接下来需要下载dubbo应用的镜像

2、下载zookeeper

docker pull zookeeper:3.4.11

3、运行zookeeper

docker run --name zookeeper-test6 --restart always -d zookeeper:3.4.11

4、下载dubbo-admin

docker pull lemonguge/dubbo-admin:latest

5、运行dubbo-admin

docker run --name dubbo-admin --link zookeeper-test6:zookeeper --restart=unless-stopped -d lemonguge/dubbo-admin:latest

6、使用用户名root密码root登录dubbo-admin管理平台进行查看，默认端口8080

7、下载应用发布使用的tomcat镜像

docker pull tomcat:8.0.50-jre8-alpine

8、使用jenkins创建发布任务，选maven,然后节点选jenkins slave的节点

9、在docker slave所在宿主机的上的发布脚本 builddocker.sh

echo "##############################################"
echo ""
echo "2.Now starting build docker images"
echo ""
echo "##############################################"

mkdir -p /home/services
mkdir -p /home/services/serviceslogs/$servicename

sed -i "s/$HOSTIP/\$DOCKER_IP/" /home/services/shell/setip.sh

10、使用pipeline方式编译发布

node('test6'){    
  stage('get Code') {  
    git credentialsId: 'b160a96c-ed57-4c69-a092-77c520016bda', url: '[email protected]/usercenter.git',branch: 'test6'
  }
    stage('编译打包') {
                echo 'Building'
                sh 'mvn clean package -Dmaven.test.skip=true -e -X'
     }
    stage('fabu') {
                echo 'Building'
                sh '/home/services/shell/builddocker.sh ordercenter test6 ${WORKSPACE} 18082 20882'
     }
}
