k8s 对接glusterfs存储

service 与 endpoint 是通过namespace相同，name相同，相互关联的
创建endpoint

[root@k8s-master glusterfs]# cat glusterfs-ep.yaml
apiVersion: v1
kind: Endpoints
metadata:
  name: glusterfs
  namespace: tomcat
subsets:
- addresses:
  - ip: 10.0.0.11
  - ip: 10.0.0.12
  - ip: 10.0.0.13
  ports:
  - port: 49152
    protocol: TCP

[root@k8s-master glusterfs]# cat glusterfs-svc.yaml
apiVersion: v1
kind: Service
metadata:
  name: glusterfs
  namespace: tomcat
spec:
  ports:
  - port: 49152
    protocol: TCP
    targetPort: 49152
  sessionAffinity: None
  type: ClusterIP

使用yml文件创建

tomcat-mysql配置文件修改

[root@k8s-master tomcat_demo]# cat mysql-rc.yml
apiVersion: v1
kind: ReplicationController
metadata:
  namespace: tomcat
  name: mysql
spec:
  replicas: 1
  selector:
    app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      volumes:
      - name: mysql
        glusterfs:
          path: oldxu
          endpoints: glusterfs
      containers:
        - name: mysql
          image: 10.0.0.11:5000/mysql:5.7
          volumeMounts:
          - name: mysql
            mountPath: /var/lib/mysql
          ports:
          - containerPort: 3306
          env:
          - name: MYSQL_ROOT_PASSWORD
            value: '123456'

删除旧的，按照新的yml文件创建
kubectl delete -f .
kubectl create -f .

提示，这里可能会有坑，原因：数据库创建时，目录必须是空的，否则无法创建数据库，我们删除/mnt的所有数据即可
