参考： ​​​​​​第七篇：kubernetes部署jenkins-CSDN博客

1、当前kubernetes集群已部署nfs服务

showmount -e

创建jenkins目录

2、添加jenkins的pvc

cd /opt/dockerfile/jenkins/

touch jenkins-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv-jenkins
spec:
  capacity:
    storage: 10Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: "pv-jenkins"
  nfs:
    path: /opt/nfsdata/jenkins
    server: 192.168.1.247

kubectl apply -f jenkins-pv.yaml

2、部署 jenkins

kubectl create namespace devops

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  namespace: devops
  name: service-reader
rules:
  - apiGroups: [""] # "" indicates the core API group
    resources: ["services"]
    verbs: ["get", "watch", "list"]
  - 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"]
