1、基于helm 部署jenkins

要求：当前集群配置了storageClass，并已指定默认的storageClass，一般情况下，创建的storageClass即为默认类 指定默认storageClass的方式

# 如果是新创建默认类：
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:name: managed-nfs-storageannotations:# 这里注解说明了这个是默认的storageclassstorageclass.kubernetes.io/is-default-class: "true"
provisioner: fuseim.pri/ifs 
parameters:archiveOnDelete: "true"# 如果是修改为默认类
kubectl patch storageclass managed-nfs-storage -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'# 检查,可以看到类后面增加了(default)
[root@kube-master ~]# kubectl get sc
NAME                            PROVISIONER                    RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
managed-nfs-storage (default)   gxf-nfs-storage                Retain          Immediate              false                  41d

1.1 部署helm

[root@kube-master ~]# wget https://get.helm.sh/helm-v3.2.4-linux-amd64.tar.gz
[root@kube-master ~]# tar zxvf helm-v3.2.4-linux-amd64.tar.gz 
[root@kube-master ~]# mv linux-amd64/helm /usr/bin/

1.2 部署jenkins

# 1、添加jenkins仓库
[root@kube-master ~]# helm repo add jenkinsci https://charts.jenkins.io && helm repo update# 2、安装jenkins
## 2.1 如果需要自定义配置，需要先将chart下载下来，如果无需修改配置，直接install即可
[root@kube-master ~]# helm pull jenkinsci/jenkins
[root@kube-master ~]# tar xf jenkins-4.8.4.tgz # 修改目录中的values.yml
[root@kube-master ~]# helm install jenkins . -f values.yaml
## 2.2 直接安装
[root@kube-master ~]# helm install jenkins jenkinsci/jenkins

1.3 检查 jenkins

# helm list
NAME    NAMESPACE       REVISION        UPDATED                                 STATUS          CHART           APP VERSION
jenkins default         1               2023-12-17 14:19:50.59739362 +0800 CST  deployed        jenkins-4.8.4   2.426.1 [root@kube-master ~]# kubectl get pod
NAME                                      READY   STATUS    RESTARTS       AGE
jenkins-0                                 2/2     Running   0              2m30s
nfs-client-provisioner-66bc5457d6-vbzfj   1/1     Running   16 (20m ago)   38d# 需要查看登录密码，可以使用
[root@kube-master ~]# helm get notes jenkins
NOTES:
1. Get your 'admin' user password by running:kubectl exec --namespace default -it svc/jenkins -c jenkins -- /bin/cat /run/secrets/additional/chart-admin-password && echo
2. Get the Jenkins URL to visit by running these commands in the same shell:echo http://127.0.0.1:8080kubectl --namespace default port-forward svc/jenkins 8080:80803. Login with the password from step 1 and the username: admin
4. Configure security realm and authorization strategy
5. Use Jenkins Configuration as Code by specifying configScripts in your values.yaml file, see documentation: http://127.0.0.1:8080/configuration-as-code and examples: https://github.com/jenkinsci/configuration-as-code-plugin/tree/master/demosFor more information on running Jenkins on Kubernetes, visit:
https://cloud.google.com/solutions/jenkins-on-container-engineFor more information about Jenkins Configuration as Code, visit:
https://jenkins.io/projects/jcasc/NOTE: Consider using a custom image with pre-installed plugins

1.4 配置访问

# 这是当前jenkins的服务，将他改为nodeport，或通过ingress代理
[root@kube-master ~]# kubectl get svc jenkins
NAME      TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)    AGE
jenkins   ClusterIP   10.99.36.63   <none>        8080/TCP   32h[root@kube-master ~]# vim ingress.yml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:labels:name: myingressname: myingressnamespace: default
spec:ingressClassName: nginxrules:- host: qf.jenkins.viphttp:paths:- backend:service:name: jenkinsport:number: 8080path: /pathType: Prefix

2、安装插件

插件列表： 将准备好的插件包，替换掉对应的pv数据卷中的plugins目录

3、准备工作

3.1 准备ruoyi数据

[root@kube-master ~]# git clone https://gitea.beyourself.org.cn/newrain001/RuoYi-Vue-cloud.git
[root@kube-master ~]# cd RuoYi-Vue-cloud/
[root@kube-master RuoYi-Vue-cloud]# ls
bin  cloud  doc  LICENSE  pom.xml  README.md  ruoyi-admin  ruoyi-common  ruoyi-framework  ruoyi-generator  ruoyi-quartz  ruoyi-system  ruoyi-ui  ry.bat  ry.sh  sql
[root@kube-master RuoYi-Vue-cloud]# cd sql/
[root@kube-master sql]# ls
quartz.sql  ry_20230223.sql
[root@kube-master sql]# kubectl create configmap ruoyi-init-data --from-file=.

3.2 准备k8s证书

[root@kube-master ~]# kubectl create secret generic kubeconfig --from-file=/root/.kube/config

3.3 准备maven配置文件

[root@kube-master ~]# vim settings.xml
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd"><pluginGroups></pluginGroups><proxies></proxies><servers></servers><mirrors><mirror><id>aliyunmaven</id><mirrorOf>*</mirrorOf><name>阿里云公共仓库</name><url>https://maven.aliyun.com/repository/public</url></mirror></mirrors><profiles></profiles>
</settings>
[root@kube-master ~]# kubectl create configmap maven-repo --from-file=settings.xml

3.4 配置钉钉插件

在系统管理的下方有未归类的插件

4、项目配置

4.1 创建pipeline项目

 

4.2 配置参数

# 参数内容:
字符参数：
PROJECT_NAME 项目名称
凭据参数：
DOCKER_REPOSITORY_CREDENTIAL_ID 需要推送的docker镜像仓库凭据id，可指定多个，然后加介绍
选项参数：
HARBOR_HOST 需要推送的镜像仓库，可以指定多个，需要与凭据对应
选项参数：
NAMESPACE_NAME 需要推送的命名空间
字符参数：后端镜像的tag
JAVA_TAG
字符参数：前端镜像的tag
NODE_TAG
字符参数：
JAVA_REPLICAS 后端副本数
