安装jenkins

创建pvc,pv

[root@kubeadm-master2 jenkins]# cat pv.yamlapiVersion: v1kind: PersistentVolumemetadata:name: pv6spec:capacity:storage: 5GiaccessModes:- ReadWriteManystorageClassName: "managed-nfs-storage6"persistentVolumeReclaimPolicy: Retainnfs:path: /root/data/pv6server: 192.168.1.209[root@kubeadm-master2 jenkins]# cat pvc.yamlapiVersion: v1kind: PersistentVolumeClaimmetadata:name: jenkins-data6namespace: kube-devopsspec:accessModes:- ReadWriteManystorageClassName: "managed-nfs-storage6"resources:requests:storage: 5Gi

# 进入 jenkins 目录，安装 jenkinskubectl apply -f manifests/# 查看是否运行成功kubectl get po -n kube-devops# 查看 service 端口，通过浏览器访问kubectl get svc -n kube-devops# 查看容器日志，获取默认密码kubectl logs -f pod名称 -n kube-devops[root@kubeadm-master2 jenkins]# kubectl logs -f jenkins-7c558dd78b-bsp9x -n kube-devops里面写了密码
