k8s部署jenkins

news 2025/8/24 23:07:36

1.先决条件

1.因为国内的容器镜像加速器无法实时更新docker hub上的镜像资源.所以可以自己进行jenkins的容器镜像创建,.

2.这里用到了storageClass k8s的动态制备.详情参考:

k8s-StoargClass的使用-基于nfs-CSDN博客

3.安装docker服务.(用于构建docker image)

2.构建jenkins镜像

1.创建Dockerfile用于构建jenkins容器镜像.

[root@master /zpf/jenkins]$cat Dockerfile
FROM jenkins/jenkins:latest
ADD ./apache-maven-3.9.4-bin.tar.gz /usr/local/
COPY ./sonar-scanner-4.8.0.2856-linux /usr/localENV MAVEN_HOME=/user/local/apache-maven-3.9.4
ENV PATH=$JAVE_HOME/bin/:$MAVEN_HOME/bin:$PATH
USER root
RUN echo "jenkins ALL=NOPASSWORD: ALL" >> /etc/sudoersUSER jenkins

2.构建docker镜像

这里下载了maven 和sonarqube将这两个包一起打入容器镜像中.下载地址:

Maven – Download Apache Maven

SonarScanner

[root@master /zpf/jenkins]$ls
apache-maven-3.9.4-bin.tar.gz  Dockerfile  github-jenkins  manifests  sonar-scanner-4.8.0.2856-linux  sonar-scanner-cli-4.8.0.2856-linux.zip
[root@master /zpf/jenkins] docker build -t 192.168.75.35:8858/scorpio/jenkins-maven:v1 .

3.上传到自己搭建的harbor容器镜像仓库

[root@master /zpf/jenkins]$ docker push 192.168.75.35:8858/scorpio/jenkins-maven:v1

4.编辑jenkins-ServiceAccount 文件

[root@master /zpf/jenkins/manifests]$vim jenkins-serviceAccount.yaml1 apiVersion: v12 kind: ServiceAccount3 metadata:4   name: jenkins-admin5   namespace: default6 ---7 apiVersion: rbac.authorization.k8s.io/v18 kind: ClusterRoleBinding9 metadata:10   name: jenkins-admin11 roleRef:12   apiGroup: rbac.authorization.k8s.io13   kind: ClusterRole14   name: cluster-admin15 subjects:16 - kind: ServiceAccount17   name: jenkins-admin18   namespace: default

5.创建sa

[root@master /zpf/jenkins/manifests]$kubectl create -f jenkins-serviceAccount.yaml

6.查看sa创建状态,以及角色权限

[root@master /zpf/jenkins/manifests]$kubectl get sa |grep jenkins
jenkins-admin            1         5d2h
[root@master /zpf/jenkins/manifests]$kubectl get ClusterRoleBinding |grep jenkins
jenkins-admin                                          ClusterRole/jenkins-admin                                                          5d2h
[root@master /zpf/jenkins/manifests]$kubectl get ClusterRole |grep jenkins
jenkins-admin                                                          2023-11-23T08:33:36Z

7.创建pvc文件(这里用到了storageClass)

[root@master /zpf/jenkins/manifests]$cat jenkins-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:name: jenkins-pvcnamespace: default
spec:storageClassName: managed-nfs-storageaccessModes:- ReadWriteManyresources:requests:storage: 1G

8. 创建pvc

[root@master /zpf/jenkins/manifests]$kubectl create -f jenkins-pvc.yaml

9.查看创建结果

[root@master /zpf/jenkins/manifests]$kubectl get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM                                                              STORAGECLASS          REASON   AGE
pvc-b1c1b782-47d7-42ce-be60-8e5d832d21bc   1Gi        RWX            Delete           Bound    default/sonarqube-data-pvc                                         managed-nfs-storage            3h25m
pvc-b35e5912-99be-4c02-a164-5ea5e385b0a4   1G         RWX            Delete           Bound    default/jenkins-pvc                                                managed-nfs-storage            29h
pvc-b7cdc67e-f66a-4602-84ef-e59c741487e2   2Gi        RWX            Delete           Bound    default/postgres-data                                              managed-nfs-storage            3h24m

[root@master /zpf/jenkins/manifests]$kubectl get pvc
NAME                 STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS          AGE
jenkins-pvc          Bound    pvc-b35e5912-99be-4c02-a164-5ea5e385b0a4   1G         RWX            managed-nfs-storage   29h

10.创建sts yaml文件并绑定svc

[root@master /zpf/jenkins/manifests]$cat sts-jenkins.yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:name: jenkinsnamespace: default
spec:serviceName: "jenkins"replicas: 1selector:matchLabels:app: jenkinstemplate:metadata:labels:app: jenkinsspec:serviceAccountName: jenkins-admincontainers:- name: jenkinsimage: 192.168.75.35:8858/scorpio/jenkins-maven:v1

#            path: settings.xml- name: daemonhostPath:path: /etc/docker/- name: kubectlhostPath:path: /usr/local/bin/kubectl

11.创建sts服务

[root@master /zpf/jenkins/manifests]$kubectl get deploy
NAME                     READY   UP-TO-DATE   AVAILABLE   AGE
nfs-client-provisioner   1/1     1            1           7d3h
postgres-sonar           1/1     1            1           3h25m
sonarqube                1/1     1            1           3h22m

12.创建svc并绑定svc

[root@master /zpf/jenkins/manifests]$cat service-jenkins.yaml
apiVersion: v1
kind: Service
metadata:name: jenkinsnamespace: default
spec:type: NodePortports:- name: httpport: 8080targetPort: 8080nodePort: 31400- name: agentport: 50000targetPort: 50000nodePort: 31401selector:app: jenkins

13.创建svc

[root@master /zpf/jenkins/manifests]$kubectl get svc
NAME              TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                          AGE

kubernetes        ClusterIP   10.233.0.1      <none>        443/TCP                          14d
sonarqube         NodePort    10.233.55.245   <none>        9000:32273/TCP                   3h15m

14.查看页面

[root@master /zpf/jenkins/manifests]$kubectl get svc
