kubernetes集群内部署jenkins

1.首先创建pv和pvc 用于Jenkins的存储

apiVersion: v1
kind: PersistentVolume
metadata:
  name: opspv
spec:
  capacity:
    storage: 20Gi
  accessModes:
  - ReadWriteMany
  persistentVolumeReclaimPolicy: Delete
  nfs:
    server: 192.168.111.118
    path: /data/nfs/jenkins

---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: opspvc
  namespace: kube-ops
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 20Gi

制作jenkins对k8s集群操作的用户权限

apiVersion: v1
kind: ServiceAccount
metadata:
  name: jenkins2
  namespace: kube-ops

---

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: jenkins2
rules:
  - apiGroups: ["extensions", "apps"]
    resources: ["deployments"]
    verbs: ["create", "delete", "get", "list", "watch", "patch", "update"]
  - apiGroups: [""]
    resources: ["services"]
    verbs: ["create", "delete", "get", "list", "watch", "patch", "update"]
  - 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: ClusterRoleBinding
metadata:
  name: jenkins2
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: jenkins2
subjects:
  - kind: ServiceAccount
    name: jenkins2
    namespace: kube-ops

3.创建jenkins的Deployment和Service

---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: jenkins2
  namespace: kube-ops
spec:
  template:
    metadata:
      labels:
        app: jenkins2
    spec:
      terminationGracePeriodSeconds: 10
      serviceAccountName: jenkins2
      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: 2Gi
          requests:
            cpu: 1000m
            memory: 1024Mi
        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: jenkins2
          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: jenkins2
  namespace: kube-ops
  labels:
    app: jenkins2
spec:
  selector:
    app: jenkins2
  type: NodePort
  sessionAffinity: ClientIP
  ports:
  - name: web
    port: 8080
    targetPort: web
    nodePort: 30006
  - name: agent
    port: 50000
    targetPort: agent
