k8s中安装jenkins

标签：kubectl 插件 name jenkins k8s 安装 port

编写jenkins.yaml

说明：

　　容器跑起来后，jenkins的目录是/var/jenkins_home

　　存储卷用的是hostPath，这里面我们指定pod调度到k8s-master01

在k8s-master01上创建目录：mkdir /data_jenkins

创建名称空间：kubectl create ns jenkins

jenkins.yaml

kind: Deployment
apiVersion: apps/v1
metadata:
  name: jenkins
  namespace: jenkins
spec:
  replicas: 1
  selector:
    matchLabels:
      app: jenkins

      containers:
      - name: jenkins
        image: jenkins/jenkins:latest
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 8080
          name: web
          protocol: TCP
        - containerPort: 50000
          name: agent
          protocol: TCP
        resources:
          limits:
            cpu: 2000m

          requests:
            cpu: 500m
            memory: 512Mi
        livenessProbe:
          httpGet:
            path: /login
            port: 8080
          initialDelaySeconds: 60
          timeoutSeconds: 5
          failureThreshold: 12
        readinessProbe:
          httpGet:
            path: /login
            port: 8080
          initialDelaySeconds: 60
          timeoutSeconds: 5
          failureThreshold: 12
        volumeMounts:
        - name: jenkins-volume
          mountPath: /var/jenkins_home
      volumes:
      - name: jenkins-volume
        hostPath:
          path: /data_jenkins
          type: DirectoryOrCreate

---
apiVersion: v1
kind: Service
metadata:
  name: jenkins-svc
  namespace: jenkins
  labels:
    app: jenkins
spec:
  selector:
    app: jenkins
  type: NodePort
  ports:
  - name: web
    port: 8080
    targetPort: web
    nodePort: 30667
  - name: agent
    port: 50000
    targetPort: agent

 

另外，jenkins在容器中的uid是1000，赋予其宿主机上目录的权限：chown -R 1000.1000 /data_jenkins

 

创建资源

应用资源文件：kubectl apply -f jenkins.yaml

查看pod：kubectl get po -n jenkins -owide

 

查看svc：kubectl get svc -n jenkins

 

通过k8s集群任意一个节点访问：192.168.117.161:30667

 

进入容器查看密码：

kubectl exec -it -n jenkins po/jenkins-dd6c9cdcd-m9964 -- sh

 密码是： 1e45bee7642d44e3acd5e9563f1bebf2

也可以在宿主机上查看密码：

 

输入密码，点击“继续”

 

选择“安装推荐的插件”

 

 此步耗时较多，需要耐心等待

 

 

 

点击“继续”，创建第一个管理员用户

 

 

配置站点

也就是更改插件源为国内插件源，否则下载插件会很慢

URL中输入如下内容：

https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

点击“立即获取”
