1、k8s1.28.2、helm3.12.0，集群搭建

查看节点运行情况

kubectl get node -o wide

openebs部署情况

kubectl get sc -n openebs

2、添加Jenkins Helm仓库

helm repo add jenkins https://charts.jenkins.iohelm repo update# 查看版本
helm search repo -l jenkins/jenkins

3、创建命名空间

kubectl create namespace jenkins

看看有哪些 可用的StorageClass

kubectl get storageclass

4、配置jenkins-values.yaml：（顺带JDK17、调度到zk3节点，用openebs-hostpath存储）

controller:numExecutors: 2image:registry: docker.iorepository: jenkins/jenkinstag: lts-jdk17serviceType: NodePortnodePort: 30080persistence:enabled: truestorageClass: openebs-hostpathsize: 8GinodeSelector:kubernetes.io/hostname: zk3additionalVolumes:- name: host-mavenhostPath:path: /opt/maventype: DirectoryadditionalVolumeMounts:- name: host-mavenmountPath: /opt/mavensidecars:containers:- name: kanikoimage: gcr.io/kaniko-project/executor:latestimagePullPolicy: IfNotPresentcommand: ["/busybox/cat"]tty: truevolumeMounts:- name: kaniko-secretmountPath: /kaniko/.docker- name: host-mavenmountPath: /opt/mavenvolumes:- name: kaniko-secretsecret:secretName: regcredresources:limits:cpu: 2memory: 4Girequests:cpu: 1memory: 2Girbac:create: trueserviceAccount:create: true

执行安装：

#如果之前存在，则先清空
helm uninstall jenkins -n jenkins#安装
helm upgrade --install jenkins jenkins/jenkins \-n jenkins \-f jenkins-values.yaml

安装完成：

 5、进入http://ip:30080，配置Manage Jenkins ---->Plugins

gitlab、harbor、maven、docker、Kubernetes、Config File Provider等插件，
所有提示更新的插件都要更新，尤其是Kubernetes

拿到初始密码

kubectl -n jenkins get secret jenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 -d && echo

配置gitlab：（配置api-token，用的是gitlab中头像下preferences的Access Tokens，没有就创建一个）

 

docker部署nexus私有库、在jenkins中全局Tools中配置maven的settings.xml

6、Manage Jenkins ---->Managed files配置setting私有库nexus连接

#如果没安装nexus私有库，找一个node节点用docker安装即可
docker run -d --name nexus   -p 8081:8081  -v /opt/sonatype/sonatype-work:/nexus-data  sonatype/nexus3#在/opt/sonatype/sonatype-work下找到admin.password拿到密码登录
http://ip:8081#登录后修改账号/密码，settings.xml要用到，这个settings.xml就是maven的，也可以本地构建推送到nexus仓库#新增一个配置
Add a new Config#选择
Maven settings.xml#改掉下面的id为：
my-settings	#点击下一步#在Content中配置加入以下内容<servers><server><id>nexus</id><username>admin</username><password>ok5201314</password> <!-- 换成你自己的密码 --></server></servers><mirrors><!-- 阿里云仓库，个人配置 --><mirror><id>alimaven</id><mirrorOf>central</mirrorOf><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/repositories/central/</url></mirror></mirrors><profiles><profile><id>use-nexus</id><repositories><repository><id>nexus</id><url>http://192.168.3.60:8081/repository/maven-snapshots/</url><snapshots><enabled>true</enabled></snapshots><releases><enabled>true</enabled></releases></repository></repositories></profile></profiles><activeProfiles><activeProfile>use-nexus</activeProfile></activeProfiles>

7、在微服务的pipeline script中配置如下：

gitlab-pat配置gitlab的账号/密码凭证， 通过mvn clean deploy -DskipTests --settings $MAVEN_SETTINGS推送到微服务中配置的私有库

pipeline {agent anytools {maven 'Maven-3.6.3'}environment {GIT_USER_NAME = 'root' #gitlab账号GIT_USER_EMAIL = 'admin@example.com' #gitlab邮箱}stages {stage('Checkout') {steps {checkout([$class: 'GitSCM',branches: [[name: '*/main']],extensions: [submodule(parentCredentials: true, recursiveSubmodules: true),[$class: 'UserIdentity', email: "${env.GIT_USER_EMAIL}", name: "${env.GIT_USER_NAME}"]],userRemoteConfigs: [[credentialsId: 'gitlab-pat',url: 'http://192.168.3.60:9980/spring_cloud_java/spring-cloud-parent.git']]])}}stage('Deploy to Nexus') {steps {configFileProvider([configFile(fileId: 'my-settings', variable: 'MAVEN_SETTINGS')]) {sh 'mvn clean deploy -DskipTests --settings $MAVEN_SETTINGS'}}}}post {failure {echo "构建失败！请检查日志。"}success {echo "构建并部署成功！"}}
}

代码中引入nexus私有库

8、spring-cloud-parent、common微服务中配置

<project>
<distributionManagement><snapshotRepository><id>nexus</id><url>http://192.168.3.60:8081/repository/maven-snapshots/</url></snapshotRepository></distributionManagement>
</project>

9、在user-center配置

<project>
<dependencyManagement><dependencies><!-- 引入 common 的 dependencyManagement 配置 --><dependency><groupId>org.algorithm</groupId><artifactId>common</artifactId><version>1.0-SNAPSHOT</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><dependencies>
<dependency><groupId>org.algorithm</groupId><artifactId>common</artifactId><version>1.0-SNAPSHOT</version><scope>compile</scope></dependency></dependencies><repositories><repository><id>nexus</id><url>http://192.168.3.60:8081/repository/maven-snapshots/</url><snapshots><enabled>true</enabled></snapshots><releases><enabled>true</enabled></releases></repository></repositories></project>

10、首先构建spring-cloud-parent、再构建common，如果有版本修改common，需要先构建common，再构建user-center。

11、如果在项目中用http的链接方式访问nexus私有库（如http://192.168.3.60:8081/repository/maven-snapshots/），Maven installations配置的maven版本要用3.6.3，因为3.8.1以后都要用https，所以Install automatically配置时候选了3.6.3。
