Kubernetes是一个开源的,用于管理云平台中多个主机上的容器化的应用,Kubernetes的目标是让部署容器化的应用简单并且高效(powerful),Kubernetes提供了应用部署,规划,更新,维护的一种机制。

前提条件是,有storageclass,利用pvc 创建持久化存储 创建kube-ops namespace
这里创建opspvc 另外把accessmode 换成readwritemany,因为会有多个pod 进行读写
然后部署jenkins master deployment如下 --- apiVersion: extensions/v1beta1 kind: Deployment metadata: name: jenkins namespace: kube-ops spec: template: metadata: labels: app: jenkins spec: terminationGracePeriodSeconds: 10 serviceAccountName: jenkins containers: - name: jenkins image: jenkins/jenkins:lts imagePullPolicy: IfNotPresent ports: - containerPort: 8080 name: web protocol: TCP - containerPort: 50000 name: agent protocol: TCP resources: limits: cpu: 2000m memory: 4Gi requests: cpu: 1000m memory: 2Gi 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: jenkinshome subPath: jenkins mountPath: /var/jenkins_home env: - name: LIMITS_MEMORY valueFrom: resourceFieldRef: resource: limits.memory divisor: 1Mi - name: JAVA_OPTS value: -Xmx$(LIMITS_MEMORY)m -XshowSettings:vm -Dhudson.slaves.NodeProvisioner.initialDelay=0 -Dhudson.slaves.NodeProvisioner.MARGIN=50 -Dhudson.slaves.NodeProvisioner.MARGIN0=0.85 -Duser.timezone=Asia/Shanghai securityContext: fsGroup: 1000 volumes: - name: jenkinshome persistentVolumeClaim: claimName: opspvc --- apiVersion: v1 kind: Service metadata: name: jenkins namespace: kube-ops labels: app: jenkins spec: selector: app: jenkins ports: - name: web port: 8080 targetPort: web - name: agent port: 50000 targetPort: agent
分配权限,配置rbac如下 apiVersion: v1 kind: ServiceAccount metadata: name: jenkins namespace: kube-ops --- kind: Role apiVersion: rbac.authorization.k8s.io/v1beta1 metadata: name: jenkins namespace: kube-ops rules: - apiGroups: [""] resources: ["pods"] verbs: ["create","delete","get","list","patch","update","watch"] - apiGroups: [""] resources: ["pods/exec"] verbs: ["create","delete","get","list","patch","update","watch"] - apiGroups: [""] resources: ["pods/log"] verbs: ["get","list","watch"] - apiGroups: [""] resources: ["secrets"] verbs: ["get"] --- apiVersion: rbac.authorization.k8s.io/v1beta1 kind: RoleBinding metadata: name: jenkins namespace: kube-ops roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: jenkins subjects: - kind: ServiceAccount name: jenkins namespace: kube-ops
安装k8s 插件,与k8s 目标集群进行远程连接

因为是腾讯云,并没有提供tls 客户端认证,所以直接利用账号密码,进行认证,记得,禁用https 证书检查,jenkins和k8s 就集成好了
划重点!!!:jenkins地址,这里我这里写的是内网地址以及暴露了50000端口(用来与slave 建立通信使用),因为master 和slave 分别在不通的k8s 集群里,那么需要远程进行联通,而jenkins-ui 我是以ingress 的方式对外暴露
slave 的配置

这里需要注意的是标签列表,这里填写的标签,需要在slave 所在k8s 集群的节点上进行标注,而这个名字,是label这个字段里的key 并未是value,这里要注意
job 里配置

这个意思就是 slave 会尽可能的在这个节点build 本文地址: https://www.linuxprobe.com/k8s-jenkins.html
