4.jenkins资源配置清单
1.dp.yaml
kind: Deployment apiVersion: extensions/v1beta1 metadata: name: jenkins namespace: infra labels: name: jenkins spec: replicas: 1 selector: matchLabels: name: jenkins template: metadata: labels: app: jenkins name: jenkins spec: volumes: - name: data nfs: server: hdss7-200 path: /data/nfs-volume/jenkins_home - name: docker hostPath: path: /run/docker.sock type: '' containers: - name: jenkins image: harbor.od.com/infra/jenkins:v2.190.3 imagePullPolicy: IfNotPresent ports: - containerPort: 8080 protocol: TCP env: - name: JAVA_OPTS value: -Xmx512m -Xms512m volumeMounts: - name: data mountPath: /var/jenkins_home - name: docker mountPath: /run/docker.sock imagePullSecrets: - name: harbor securityContext: runAsUser: 0 strategy: type: RollingUpdate rollingUpdate: maxUnavailable: 1 maxSurge: 1 revisionHistoryLimit: 7 progressDeadlineSeconds: 600
New：
namespace: infra 隶属于infra ns中
path: /run/docker.sock 这里挂载了宿主机的docker.sock，使容器内的docker客户端可以直接与宿主机的docker引擎进行通信
volumes nfs 类型的卷 server是运维管理主机200
imagePullPolicy 镜像拉取的策略
分为三种 1.无论如何都去从harbor仓库拉取镜像 2.无论如何都不去远程拉取 只是用本地 3.如何本地没有就去远程仓库拉
imagePullSecrets 拉取harbor私有仓库必须加此参数 否则拉取不到
2.svc.yaml
kind: Service apiVersion: v1 metadata: name: jenkins namespace: infra spec: ports: - protocol: TCP port: 80 targetPort: 8080 selector: app: jenkins
3.ingress.yaml
kind: Ingress apiVersion: extensions/v1beta1 metadata: name: jenkins namespace: infra spec: rules: - host: jenkins.od.com http: paths: - path: / backend: serviceName: jenkins servicePort: 80
4.应用资源配置清单：node节点
[root@hdss7-22 ~]# kubectl create -f http://k8s-yaml.od.com/jenkins/dp.yaml deployment.extensions/jenkins created [root@hdss7-22 ~]# kubectl create -f http://k8s-yaml.od.com/jenkins/svc.yaml service/jenkins created [root@hdss7-22 ~]# kubectl create -f http://k8s-yaml.od.com/jenkins/ingress.yaml

5.jenkins基础优化
搜索蓝海插件并安装：blue ocean
6 二进制部署mvn 200操作
cd /opt/src
[root@hdss7-200 harbor]# wget https://archive.apache.org/dist/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz
# mkdir /data/nfs-volume/jenkins_home/maven-3.6.1-8u232

制作dubbo微服务底包镜像：JAVA运行时环境的底包
[root@hdss7-200 ~]# docker pull stanleyws/jre8:8u112
[root@hdss7-200 ~]# docker pull stanleyws/jre8:8u112
[root@hdss7-200 ~]# docker tag fa3a085d6ef1 harbor.od.com/public/jre:8u112
[root@hdss7-200 ~]# docker push harbor.od.com/public/jre:8u112
[root@hdss7-200 ~]# cd /data/dockerfile/
[root@hdss7-200 dockerfile]# ls
jenkins
[root@hdss7-200 dockerfile]# mkdir jre8
[root@hdss7-200 dockerfile]# cd jre8
[root@hdss7-200 jre8]# vi Dockerfile
FROM harbor.od.com/public/jre:8u112
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\
echo 'Asia/Shanghai' >/etc/timezone
ADD config.yml /opt/prom/config.yml
ADD jmx_javaagent-0.3.1.jar /opt/prom/
WORKDIR /opt/project_dir
ADD entrypoint.sh /entrypoint.sh
CMD ["/entrypoint.sh"]
下载jmx_javaagent,监控jvm信息：
[root@hdss7-200 jre8]# wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.3.1/jmx_prometheus_javaagent-0.3.1.jar -O jmx_javaagent-0.3.1.jar
root@hdss7-200 jre8]# cat config.yml
---
rules:
- pattern: '.*'
创建entrypoint.sh：使用exec 来运行java的jar包，能够使脚本将自己的pid 为‘1’ 传递给java进程，避免docker容器因没有前台进程而退出。并且不要加&符。
[root@hdss7-200 jre8]# cat entrypoint.sh
#!/bin/sh
M_OPTS="-Duser.timezone=Asia/Shanghai -javaagent:/opt/prom/jmx_javaagent-0.3.1.jar=$(hostname -i):${M_PORT:-"12346"}:/opt/prom/config.yml"
C_OPTS=${C_OPTS}
JAR_BALL=${JAR_BALL}
exec java -jar ${M_OPTS} ${C_OPTS} ${JAR_BALL}
[root@hdss7-200 jre8]# chmod +x entrypoint.sh
# docker build . -t harbor.od.com/base/jre8:8u112
[root@hdss7-200 jre8]# docker push harbor.od.com/base/jre8:8u112
7 jenkins 参数化构建
除了base_image和maven是choice parameter，其他都是string parameter
添加完成后，效果如图：
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}" } } } }
构建时间有点久 先去抽根烟
8 资源配置清单
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
[root@hdss7-200 nginx]# mkdir /data/k8s-yaml/dubbo-server/
[root@hdss7-200 nginx]# cd /data/k8s-yaml/dubbo-server/
[root@hdss7-200 dubbo-server]# cat 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_20200602_1730 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：
# kubectl create ns app
# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=admin --docker-password=Harbor12345 -n app
# kubectl apply -f http://k8s-yaml.od.com/dubbo-server/dp.yaml
检查是否启动成功：
# kubectl logs dubbo-demo-service-77b687c6f8-v556v -n app
查看是否已经注册到zk中
