1 集群部署，需要PV，安装NFS

#master11,slave12,slave13都安装

yum install nfs-utils rpcbind -y

2 配置

#master11
vim /etc/exports
/data/share 192.168.50.0/24(sync,rw,no_root_squash)
#启动服务
systemctl enable rpcbind.service
systemctl enable nfs-server.service
systemctl start rpcbind.service
systemctl start nfs-server.service
#查看服务
[root@master11 share]# showmount -e 192.168.50.11
Export list for 192.168.50.11:
/data/share 192.168.50.0/24

#客户端

#slave12
#启动服务
systemctl enable rpcbind.service
systemctl enable nfs-server.service
systemctl start rpcbind.service
systemctl start nfs-server.service
#查看
[root@slave12 ~]# showmount -e 192.168.50.11
Export list for 192.168.50.11:
/data/share 192.168.50.0/24
#挂载
mkdir  -p /mnt/nfs
mount -t nfs 192.168.50.11:/data/share  /mnt/nfs
#查看
[root@slave12 ~]# df -h| grep nfs
192.168.50.11:/data/share   36G   16G   21G  44% /mnt/nfs
#slave13同样安装配置

3 yaml配置

[root@master11 soft]# cat  discuz.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:name: discuz
spec:replicas: 3selector:matchLabels:app: discuztemplate:metadata:labels:app: discuzspec:containers:- name: discuzimage: 192.168.50.11:5000/discuz:x3.5ports:- containerPort: 80volumeMounts:- name: host-datamountPath: /var/www/htmlvolumes:- name: host-datahostPath:path: /mnt/nfs/discuz/htmltype: DirectoryOrCreate
#
[root@master11 soft]# cat  discuz-srv.yaml 
apiVersion: v1
kind: Service
metadata:name: discuz-servicelabels:app: discuz
spec:selector:app: discuzports:- protocol: TCPport: 88targetPort: 80nodePort: 30036type: NodePort

4 创建应用

#master11
kubectl apply -f discuz.yaml
kubectl apply -f discuz-srv.yaml
#删除
kubectl delete -f discuz.yaml
kubectl delete -f discuz-srv.yaml

5 查看和访问

[root@master11 discuz]# kubectl get node,po,svc -A -owide|grep discuz
