脚本文件编写

1、查询模板脚本情况

[root@k8s-jenkins jenkins_home]# ls model/
build.sh  deploy.yaml  dockerfile  leaf.properties

2、查询dockerfile文件

[root@k8s-jenkins jenkins_home]# cat model/dockerfile 
FROM java:8
 
VOLUME /app
 
COPY INAME.jar INAME.jar
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
RUN echo 'Asia/Shanghai' >/etc/timezone
 
RUN bash -c "touch /INAME.jar"
EXPOSE 8085
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./uranedom","-jar","-Dspring.profiles.active=test", "-Dserver.port=8085", "-Duser.timezone=GMT+08", "/INAME.jar"]

3、查看build.sh文件

[root@k8s-jenkins jenkins_home]# cat model/build.sh 
#!/bin/bash
#DOCKER_HOME=/var/jenkins_home/tools/docker 
#export PATH=$PATH:$DOCKER_HOME

docker build -t $1:$2 . 
# 制作镜像
docker tag $1:$2 harbor-test.sgpexchange.com/sgpexchange_test/$1:$2 # 镜像做tar标记
docker login -u admin -p 12345 harbor-test.sgpexchange.com
docker push harbor-test.sgpexchange.com/sgpexchange_test/$1:$2 # 将镜像上传致我们的镜像库，一般都是私有镜像库

4、文件中的leaf.properties文件为服务配置文件

jenkins配置

1、配置丢弃构建

2、配置构建发布参数

3、配置git参数

4、配置java服务名称

5、配置环境参数

6、配置Pipeline Script

其中需要配置gitlab账号参数（credentialsId: ‘c5d7e5af-f442-44ed-98ff-d7a097cd4f49’）

pipeline script脚本内容

// 部署远程主机ip地址,需要通过密钥的方式设置免密登录
def remoteIp = "192.168.1.214"
def remotePort='22'
// 远程tomcat位置(windows要使用/来表示路径)
def tomcatPath = "/var/jenkins_home/image/${envir}"
def project='leaf-server'
def service='test'
def v='123'
def img=''
  node (){ //指定Slave标签

  stage('Git Checkout') {
      if("Deploy" == env.status){
                checkout([$class: 'GitSCM', branches: [[name: '${tag}']],
						userRemoteConfigs: [[credentialsId: 'c5d7e5af-f442-44ed-98ff-d7a097cd4f49', 
							url: 'http://gitlab.tqxd.com/new-sgp/leaf.git']]])
      }else{
          echo "回滚版本跳过拉取代码";
      }

	}
  stage('Maven Build') {
      if("Deploy" == env.status){
       sh '''
          MAVEN_HOME=/var/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/maven3.6.3
          export PATH=$MAVEN_HOME/bin:/var/jenkins_home/tools/jdk1.8/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
          mvn clean install  -am -Dmaven.test.skip=true
       '''
      }else{
          echo "回滚版本跳过拉取代码";
      }
       
  }
  stage('push') {
	    if("Deploy" == env.status){
		echo "pushde时间:${v}"
		sh '''
		mkdir -p /var/jenkins_home/image/${envir}/

		'''
		v = sh(script: "date +%Y%m%d.%H%M%S", returnStdout: true).trim()
		sh(script: "cd /var/jenkins_home/image/${envir}/ && ./build.sh ${name} ${envir}", returnStdout: true).trim()
		img = "harbor-test.sgpexchange.com/${name}:v${envir}"
	    }else{
          echo "回滚版本跳过拉取代码";
      }
		
  }
  stage('publish') {
      if("Rollback" == env.status){
           img = env.Deploy
      }
		sh '''
		pwd 
		'''
		echo "end的时间出:${v}"
		sh(script: "cd /var/jenkins_home/image/test && ./build.sh ${name} ${envir}", returnStdout: true).trim()
		sh '''
		echo "end img:${img}"
		'''
  }

  stage('end') {
      if("Rollback" == env.status){
      img = env.Deploy
      }
      sh(script: "scp -i /var/jenkins_home/.ssh/id_rsa.pem  /var/jenkins_home/image/${envir}/${name}.yaml root@192.168.1.214:/root/", returnStdout: true).trim()
      sh(script: "scp -i /var/jenkins_home/.ssh/id_rsa.pem -r /var/jenkins_home/image/${envir}/${name}-conf/ root@192.168.1.214:/root/", returnStdout: true).trim()
      sh(script: "ssh -i /var/jenkins_home/.ssh/id_rsa.pem -t root@192.168.1.214 'kubectl replace --force -f '${name}'.yaml'", returnStdout: true).trim()
  }
}

7、构建job查看job运行情况

k8s服务pods查询

在k8s服务中查看各种信息
1、查询pods服务

[root@k8s-master ~]# kubectl get pods -n k8s-test -o wide
NAME                           READY   STATUS    RESTARTS   AGE   IP            NODE        NOMINATED NODE   READINESS GATES
leaf-server-6c8b4d8454-r2blv   1/1     Running   0          90m   10.244.3.58   k8s-node3   <none>           <none>

2、查询service服务

[root@k8s-master ~]# kubectl get svc -n k8s-test -o wide
NAME                  TYPE       CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE   SELECTOR
leaf-server-service   NodePort   10.109.121.210   <none>        8085:31079/TCP   91m   app=leaf-server

3、查询deployment服务

[root@k8s-master ~]# kubectl get deployment -n k8s-test -o wide
NAME          READY   UP-TO-DATE   AVAILABLE   AGE   CONTAINERS    IMAGES                                                          SELECTOR
leaf-server   1/1     1            1           92m   leaf-server   harbor-test.sgpexchange.com/sgpexchange_test/leaf-server:test   app=leaf-server

4、查询configmap服务

[root@k8s-master ~]# kubectl get configmap -n k8s-test -o wide
NAME                 DATA   AGE
kube-root-ca.crt     1      3d1h
leaf-server-config   1      3d

测试

1、通过nodeport地址测试
http://192.168.1.214:31079/api/segment/get/leaf_ransom_order_id

2、宿主服务测试

至此服务部署完毕
