安装glusterfs
如果你对glusterfs不熟悉可以看这个地方:GlusterFS快速安装

在每个节点上创建目录

mkdir -p /data/volume

创建glusterfs卷

gluster volume create k8s-volume replica 3 192.168.1.253:/data/volume
192.168.1.238:/data/volume 192.168.1.244:/data/volume

启动这个卷

gluster volume start k8s-volume

创建EndPoint (k8s集群内部访问外部的集群)

---
kind: Endpoints
apiVersion: v1
metadata:
  name: glusterfs-cluster   #这个名字必须要和svc的名称一样
subsets:
- addresses:
  - ip: 192.168.1.253
  ports:
  - port: 1000
- addresses:
  - ip: 192.168.1.238
  ports:
  - port: 1000
- addresses:
  - ip: 192.168.1.244
  ports:
  - port: 1000

这个里面的port端口可以随便设置,默认是1,你可以随意设置,

创建一个svc

---

kind: Service
apiVersion: v1
metadata:
  name: glusterfs-cluster   #这个必须要和EndPoint一样
spec:
  ports:
  - port: 1000

创建一个测试pod,看看挂载是否成功

---
apiVersion: v1
kind: Pod
metadata:
  name: glusterfs-test
spec:
  containers:
  - name: glusterfs-test
    image: nginx
    volumeMounts:
    - mountPath: "/mnt/glusterfs"
      name: glusterfsvol
  volumes:
  - name: glusterfsvol
    glusterfs:
      endpoints: glusterfs-cluster
      path: k8s-volume
      readOnly: false

pv and pvc

创建一个pv

apiVersion: v1
kind: PersistentVolume
metadata:
  name: gluster-nginx-pv
  labels:
    pv: gluster-volume
spec:
  capacity:
    storage: 10Gi
  accessModes:
  - ReadWriteMany
  glusterfs:
    endpoints: glusterfs-cluster
    path: k8s-volume
    readOnly: false

创建一个pvc

---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: gluster-nginx-pvc
spec:
  selector:
    matchLabels:
      pv: gluster-volume
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Gi

创建个pod引用

apiVersion: v1
kind: Pod
metadata:
  name: nginx-test-glutser-pv
spec:
  containers:
  - name: nginx-test-glutser-pv
    image: nginx:1.14.1
    volumeMounts:
    - name: gluster-volume
      mountPath: /var/www/html
  volumes:
  - name: gluster-volume
    persistentVolumeClaim:
      claimName: gluster-nginx-pvc
