1.登录到jenkins，新建一个项目
2.新建流水线
3.设置保留的天数及份数
4.添加第一个参数：设置项目的名称
5.添加第二个参数：docker镜像名称
6.添加第三个参数：项目所在的git中央仓库地址
7.添加第四个参数：项目在git仓库的对应分支或版本号
8.添加第五个参数：添加镜像标签
9.添加第六个参数：编译项目的位置
10.添加第七个参数：项目编译完成后，产生jar/war包的位置
11.添加第八个参数：编译所要使用的命令
12.添加第九个参数：使用哪个底包
13.添加第十个参数：使用哪个maven版本编译项目
14.设置流水线构建脚本
脚本代码如下：
pipeline {
agent any
stages {
stage('pull') { //get project code from repo
steps {
sh "git clone ${params.git_repo} ${params.app_name}/${env.BUILD_NUMBER} && cd ${params.app_name}/${env.BUILD_NUMBER} && git checkout ${params.git_ver}"
}
}
stage('build') { //exec mvn cmd
steps {
sh "cd ${params.app_name}/${env.BUILD_NUMBER} && /var/jenkins_home/maven-${params.maven}/bin/${params.mvn_cmd}"
}
}
stage('package') { //move jar file into project_dir
steps {
sh "cd ${params.app_name}/${env.BUILD_NUMBER} && cd ${params.target_dir} && mkdir project_dir && mv *.jar ./project_dir"
}
}
stage('image') { //build image and push to registry
steps {
writeFile file: "${params.app_name}/${env.BUILD_NUMBER}/Dockerfile", text: """FROM harbor.od.com/${params.base_image}
ADD ${params.target_dir}/project_dir /opt/project_dir"""
sh "cd ${params.app_name}/${env.BUILD_NUMBER} && docker build -t harbor.od.com/${params.image_name}:${params.git_ver}_${params.add_tag} . && docker push harbor.od.com/${params.image_name}:${params.git_ver}_${params.add_tag}"
}
}
}
}
15.最后保存所有设置的
16.在私有仓库创建一个名称为app的项目，属性为私有
17.执行流水线
18.输入相关的参数，执行build
19.构建成功
20.查看私有仓库的app项目是否已经有docker镜像
21.准备dubbo-demo-service的k8s资源配置清单文件
在运维主机mfyxw50.mfyxw.com上操作
[root@mfyxw50 ~]# mkdir -p /data/k8s-yaml/dubbo-demo-service
[root@mfyxw50 ~]# cat > /data/k8s-yaml/dubbo-demo-service/deployment.yaml << EOF

在安装有zookeeper的主机(mfyxw10或mfyxw20或mfyxw30)上任意一台执行
查看zookeeper的状态
[root@mfyxw30 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: follower
连接进入zookeeper查看
[root@mfyxw30 bin]# ./zkCli.sh -server localhost:2181
[zk: localhost:2181(CONNECTED) 0] ls /
[zookeeper]
[zk: localhost:2181(CONNECTED) 1]
23.应用dubbo-demo-service的k8s的资源配置清单
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)任意一台执行即可
[root@mfyxw30 ~]# kubectl create namespace app
[root@mfyxw30 ~]# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=admin --docker-password=Harbor12345 -n app
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/dubbo-demo-service/deployment.yaml
再次查看zookeeper
[zk: localhost:2181(CONNECTED) 1] ls /
[dubbo, zookeeper]
[zk: localhost:2181(CONNECTED) 2] ls /dubbo
24.打开 Blue Ocean可以查看到构建的步骤
