Pipeline Script

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('package') { //move jar file into project_dir
        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}"
        }

在harbor中创建一个app项目

2. Jenkins—>build

第一次就躺枪了。。。。。。。。。

[ERROR] Non-resolvable parent POM for com.od.dubbotest:dubbo-server:0.0.1-SNAPSHOT: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:1.3.1.RELEASE from/to spring-snapshots (http://repo.spring.io/snapshot): repo.spring.io: Temporary failure in name resolution and ‘parent.relativePath’ points at wrong local POM @ line 14, column 10: Unknown host repo.spring.io: Temporary failure in name resolution -> [Help 2]

解决方案

root@jenkins-7c85c8cb57-m6cvg:~# rm -rf .m2
再一次build··········

检查harbor仓库：

3. 交付dubbo-service到k8s

准备k8s资源配置清单

[root@k8s7-200.host.com ~]# mkdir -p /data/k8s-yaml/dubbo-server
[root@k8s7-200.host.com /data/k8s-yaml/dubbo-server]# cat deployment.yaml
kind: Deployment
apiVersion: extensions/v1beta1
metadata:
  name: dubbo-demo-service
  namespace: app
  labels: 
    name: dubbo-demo-service
    tier: provider
spec:
  replicas: 1
  selector:
    matchLabels: 
      name: dubbo-demo-service
  template:
    metadata:
      labels: 
        app: dubbo-demo-service
        name: dubbo-demo-service
        version: master_200813_2300
    spec:
      containers:
      - name: dubbo-demo-service
        image: harbor.od.com/app/dubbo-demo-service:master_200813_2300
        env:
        - name: JAR_BALL
          value: dubbo-server.jar
      imagePullSecrets:
      - name: harbor
      terminationGracePeriodSeconds: 30
  strategy:
    type: RollingUpdate
    rollingUpdate: 
      maxUnavailable: 0
      maxSurge: 1
  revisionHistoryLimit: 10
  progressDeadlineSeconds: 600

需要根据自己构建镜像的tag来修改image
dubbo的server服务,只向zk注册并通过zk与dobbo的web交互,不需要对外提供服务
因此不需要service资源和ingress资源

1.创建k8s资源
创建K8S资源的操作,在任意node节点上操作即可

2.创建app名称空间
业务资源和运维资源等应该通过名称空间来隔离,因此创建专有名称空间app
kubectl create namespace app

3.创建secret资源
我们的业务镜像是harbor中的私有项目，所以需要创建docker-registry的secret资源：

[root@k8s7-21.host.com ~]# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=admin --docker-password=Harbor12345 -n app

检查zk
[root@k8s7-11.host.name /opt/zookeeper]# bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Mode: follower
[root@k8s7-11.host.name /opt/zookeeper]# bin/zkCli.sh -server localhost:2181
[zk: localhost:2181(CONNECTED) 0] ls /
[zookeeper]

4.应用资源清单
[root@k8s7-21.host.com ~]# kubectl apply -f http://k8s-yaml.od.com/dubbo-server/deployment.yaml

[zk: localhost:2181(CONNECTED) 1] ls /
[dubbo, zookeeper]

[zk: localhost:2181(CONNECTED) 2] ls /dubbo
[com.od.dubbotest.api.HelloService]
