kubernetes实战-交付dubbo服务到k8s集群(四)使用blue ocean流水线构建dubbo-demo-service
使用jenkins创建一个新的项目:dubbo-demo,选择流水线构建
勾选保存构建历史和指定项目为参数化构建项目:
添加构建参数:以下配置项,是王导根据多年生产经验总结出来的甩锅大法:
除了base_image和maven是choice parameter,其他都是string parameter
添加完成后,效果如图:
编写pipeline:仔细查看这个pipeline,里面都是我们上面编写的参数。
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}" } } } }
完成第一次构建:填写我们刚才配置的参数化构建参数:
填写完以后执行bulid:第一次构建需要下载很多依赖包,时间很长,抽根烟,喝杯茶~
经过漫长的等待后,已经构建完成了,可以点击open blue ocean 查看构建历史及过程:
检查harbor是否已经有这版镜像:
已经有了,接下来交付dubbo-demo-service服务到k8s:
准备k8s资源配置清单:7-200 红色部分,需要根据自己构建镜像的tag来进行修改
# mkdir /data/k8s-yaml/dubbo-server/
# cd /data/k8s-yaml/dubbo-server
# vi dp.yaml
kind: Deployment apiVersion: extensions/v1beta1 metadata: name: dubbo-demo-service namespace: app labels: name: dubbo-demo-service spec: replicas: 1 selector: matchLabels: name: dubbo-demo-service template: metadata: labels: app: dubbo-demo-service name: dubbo-demo-service spec: containers: - name: dubbo-demo-service image: harbor.od.com/app/dubbo-demo-service:master_191201_1200 ports: - containerPort: 20880 protocol: TCP env: - name: JAR_BALL value: dubbo-server.jar imagePullPolicy: IfNotPresent imagePullSecrets: - name: harbor restartPolicy: Always terminationGracePeriodSeconds: 30 securityContext: runAsUser: 0 schedulerName: default-scheduler strategy: type: RollingUpdate rollingUpdate: maxUnavailable: 1 maxSurge: 1 revisionHistoryLimit: 7 progressDeadlineSeconds: 600
由于我们使用的harbor私有镜像的项目是app,是个私有项目,所以需要创建secret资源:
创建 app命名空间:
# kubectl create ns app
创建secret资源:
# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=admin --docker-password=Harbor12345 -n app
应用资源配置文件:
# kubectl apply -f http://k8s-yaml.od.com/dubbo-server/dp.yaml
检查pod是否创建:
# kubectl get pod -n app
检查是否启动成功:
# kubectl logs dubbo-demo-service-77b687c6f8-v556v -n app
检查dubbo-server服务是否已经注册到了zookeeper:
# sh /opt/zookeeper/bin/zkCli.sh
# ls /
# ls /dubbo
至此,dubbo-demo-service就已经交付到k8s中了。
