| 192.168.147.35 alpha-pack.51iwifi.com
192.168.195.3 k8s-alpha-node2
192.168.195.70 dev-harbor.51iwifi.com
192.168.195.2 alpha-harbor.51iwifi.com
|
二、docker地址修改
1
| vi /etc/docker/daemon.json
|
三、nfs搭建，master节点执行即可
路径：/k8s，文件
1).安装NFS服务
1
2
| env http_proxy=http://172.200.96.179:3128 yum install -y nfs-utils
env http_proxy=http://172.200.96.179:3128 yum install -y rpcbind
|
2).设置共享文件夹
1
2
| mkdir -p /nfs/data/
chmod 755 /nfs/data
|
3).配置文件修改
1

4
| vim /etc/exports加入以下内容：
/nfs/ *(async,insecure,no_root_squash,no_subtree_check,rw)
/nfs/data/ *(async,insecure,no_root_squash,no_subtree_check,rw)
使配置生效：exportfs -r
|
4).启动服务
1

4
| systemctl start rpcbind
systemctl start nfs
systemctl enable rpcbind # 设置开机启动
systemctl enable nfs-server.service # 设置开机启动
|
5).把dev-harbor.51iwifi.com/k8s-depend/quay.io/external_storage/nfs-client-provisioner:latest镜像加载到各个节点上
6).kubectl create -f cluster-admin.rbac.yaml 创建权限（以下为cluster-admin.rbac.yaml内容）

7).kubectl create -f nfs-client-provisioner.yaml创建nfs-client-provisioner（以下为nfs-client-provisioner.yaml内容）
kind: Deployment
apiVersion: apps/v1
metadata:
name: nfs-client-provisioner
namespace: kube-system
spec:
replicas: 1

value: /nfs/data
volumes:
- name: nfs-client-root
nfs:
server: 172.20.131.251
path: /nfs/data

| apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: managed-nfs-storage
provisioner: fuseim.pri/ifs
9).创建pvc使用对应nfs-client-provisioner验证nfs是否配置成功
kubectl create -f nfs-client-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: nfs-client-pvc
namespace: kube-system
spec:
accessModes:
- ReadWriteMany
storageClassName: managed-nfs-storage
resources:
requests:
storage: 100Mi
|
. 查看pvc 是否自动关联上pv
1
| kubectl delete pvc nfs-client-pvc -n kube-system 验证结束后删除pvc
|
四、consul pod创建
五、consul配置导出
1
| kubectl exec -it consul-0 consul kv export > test`date +%y%m%d`.json
|
六、consul配置导入

| kubectl cp testvideo.json consul-0:/
kubectl exec -it consul-0 sh
consul kv import @testvideo.json
