基于docker部署
1.部署jenkins

$ yum -y install  java

$ java -version

openjdk version "1.8.0_181"

OpenJDK Runtime Environment (build 1.8.0_181-b13)

OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)

$ wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

$ rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

$ yum -y install jenkins

2.部署gitlab

$ wget https://mirror.tuna.tsinghua.edu.cn/gitlab-ce/yum/el6/gitlab-ce-9.1.3-ce.0.el6.x86_64.rpm

$ rpm -ivh gitlab-ce-9.1.3-ce.0.el6.x86_64.rpm

$ gitlab-ctl reconfigure

$ gitlab-ctl start

3.harbor仓库部署

4.gitlab新建项目

5.jenkins配置

node{

    stage('git下载'){

        //check CODE

        git credentialsId: '664b2611-19e9-458f-beba-e215bbcb96f1', url: 'git@gitlab.example.com:root/my-test.git'

    }

    stage('构建'){

        sh '''

cd /root/.jenkins/workspace/pipe/

cat >Dockerfile <<EOF

FROM tomcat:tomcat

RUN rm -rf /usr/src/tomcat/webapps/ROOT/index.jsp

COPY ./index.jsp  /usr/src/tomcat/webapps/ROOT/

WORKDIR /usr/src/tomcat

EXPOSE 9090

ENTRYPOINT ["./bin/catalina.sh", "run"]

EOF

    '''

    }

    stage('上传到仓库'){

        sh '''

docker build -t tomcat:2 .

docker tag tomcat:2 www.zam.com/os/tomcat:2

docker login -u admin -p Harbor12345 www.zam.com

docker push www.zam.com/os/tomcat:2

docker rmi www.zam.com/os/tomcat:2

docker rmi tomcat:2

        '''

    }

    stage('给docker集群部署'){

        sh '''

ssh  192.168.16.238  'bash -x -s'  </root/test.sh

        '''

    }

}

6.jenkins主机编写脚本（需要源镜像tomcat）

#!/bin/bash

docker login  -u admin  -p Harbor12345  www.zam.com

docker rmi  -f www.zam.com/os/tomcat:2

docker pull  www.zam.com/os/tomcat:2

docker rm -f  tomcat

docker run -itd   --name tomcat --net host   www.zam.com/os/tomcat:2

7.构建
