一、安装glusterfs
https://www.cnblogs.com/zhangb8042/p/7801181.html
环境介绍;
centos 7
[root@k8s-m ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.31.250.144 k8s-m
172.31.250.145 node
配置好信任池 [root@k8s-m ~]# gluster peer status Number of Peers: 1 Hostname: node Uuid: 550bc83e-e15b-40da-9f63-b468d6c7bdb9 State: Peer in Cluster (Connected) 2、创建目录 mkdir /data 3、创建glusterfs的复制卷 [root@node yum.repos.d]# gluster volume create gv0 replica 2 k8s-m:/data node:/data force volume create: gv0: success: please start the volume to access data 4、启动卷 [root@node yum.repos.d]# gluster volume start gv0 volume start: gv0: success 5、查看 [root@k8s-m ~]# gluster volume status gv0 Status of volume: gv0 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick k8s-m:/data 49152 0 Y 7925 Brick node:/data 49152 0 Y 18592 Self-heal Daemon on localhost N/A N/A Y 7948 Self-heal Daemon on node N/A N/A Y 18615 Task Status of Volume gv0 ------------------------------------------------------------------------------ There are no active volume tasks
二、k8s配置
1、配置 endpoints
[root@k8s-m ~]# cat glusterfs-endpoints.json
{
"kind": "Endpoints",
"apiVersion": "v1",
"metadata": {
"name": "glusterfs-cluster"
},
"subsets": [
{
"addresses": [
{
"ip": "172.31.250.144"
}
],
"ports": [
{
"port": 1000
}
]
},
{
"addresses": [
{
"ip": "172.31.250.145"
}
],
"ports": [
{
"port": 1000
}
]
}
]
}
#导入
kubectl apply -f glusterfs-endpoints.json
#查看
[root@k8s-m ~]# kubectl get ep
NAME ENDPOINTS AGE
glusterfs-cluster 172.31.250.144:1000,172.31.250.145:1000 17m
kubernetes 172.31.250.144:6443 24m
2、配置 service
[root@k8s-m ~]# cat glusterfs-service.json { "kind": "Service", "apiVersion": "v1", "metadata": { "name": "glusterfs-cluster" }, "spec": { "ports": [ {"port": 1000} ] } } #导入 kubectl apply -f glusterfs-service.json #查看 [root@k8s-m ~]# kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE glusterfs-cluster ClusterIP 10.105.177.109 <none> 1000/TCP 17m kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 24m
3、创建测试 pod
[root@k8s-m ~]# cat glusterfs-pod.json { "apiVersion": "v1", "kind": "Pod", "metadata": { "name": "glusterfs" }, "spec": { "containers": [ { "name": "glusterfs", "image": "nginx", "volumeMounts": [ { "mountPath": "/mnt/glusterfs", "name": "glusterfsvol" } ] } ], "volumes": [ { "name": "glusterfsvol", "glusterfs": { "endpoints": "glusterfs-cluster", "path": "gv0", #之前创建的glusterfs卷名 "readOnly": true } } ] } }
#导入
kubectl apply -f glusterfs-pod.json
#查看
kubectl get pod
4、创建pv
[root@k8s-m ~]# cat glusterfs-pv.yaml apiVersion: v1 kind: PersistentVolume metadata: name: gluster-dev-volume spec: capacity: storage: 8Gi accessModes: - ReadWriteMany glusterfs: endpoints: "glusterfs-cluster" path: "gv0" readOnly: false #导入 kubectl apply -f glusterfs-pv.yaml #查看 kubectl get pv
5、创建pvc
[root@k8s-m ~]# cat glusterfs-pvc.yaml kind: PersistentVolumeClaim apiVersion: v1 metadata: name: glusterfs-nginx spec: accessModes: - ReadWriteMany resources: requests: storage: 8Gi #导入 kubectl apply -f glusterfs-pvc.yaml #查看 [root@k8s-m ~]# kubectl get pvc NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE glusterfs-nginx Bound gluster-dev-volume 8Gi RWX 11m
6、创建挂载卷测试
[root@k8s-m ~]# cat nginx-deployment.yaml apiVersion: extensions/v1beta1 kind: Deployment metadata: name: nginx-dm spec: replicas: 2 template: metadata: labels: name: nginx spec: containers: - name: nginx image: nginx:alpine imagePullPolicy: IfNotPresent ports: - containerPort: 80 volumeMounts: - name: gluster-dev-volume mountPath: "/usr/share/nginx/html" volumes: - name: gluster-dev-volume persistentVolumeClaim: claimName: glusterfs-nginx #导入 kubectl apply -f nginx-deployment.yaml #查看 [root@k8s-m ~]# kubectl get pod NAME READY STATUS RESTARTS AGE glusterfs 1/1 Running 0 15m nginx-dm-8df56c754-57kpp 1/1 Running 0 12m nginx-dm-8df56c754-kgsbf 1/1 Running 0 12m #进入一个pod测试 [root@k8s-m ~]# kubectl exec -it nginx-dm-8df56c754-kgsbf -- /bin/sh / # ls /usr/share/nginx/html/ / # cd /usr/share/nginx/html/ /usr/share/nginx/html # touch 111.txt /usr/share/nginx/html # ls 111.txt #在node节点查看/data目录 [root@node ~]# ll /data/ total 4 -rw-r--r-- 2 root root 0 Jan 10 14:17 111.txt
