无法与glusterfs

Question

量运行的容器我曾与一个主节点和3个爪牙一个kubernetes集群，我已经一个glusterfs集群，kubernetes群集的每个节点都安装glusterfs客户端和工作。 我试图运行一个POD（一个简单的MySQL）安装在/ var/lib中/ MySQL在glusterfs但我看到：

Image: mysql:5.6 is ready, container is creating 

我运行： kubectl得到事件 我看到：

如果我跑 kubectl描述荚的mysql-9ym10 我看到：

这是YAML文件集装箱：

apiVersion: v1 
kind: ReplicationController 
metadata: 
    name: mysql 
spec: 
    replicas: 1 
    selector: 
    app: mysql 
    template: 
    metadata: 
     name: mysql 
     labels: 
     app: mysql 
    spec: 
     containers: 
     - name: mysql 
     image: mysql:5.6 
     ports: 
     - containerPort: 3306 
     env: 
      - name: MYSQL_ROOT_PASSWORD 
      value: password 
     volumeMounts: 
      - mountPath: /var/lib/mysql 
      name: glusterfsvol 
     volumes: 
     - glusterfs: 
      endpoints: glusterfs-cluster 
      path: glustervolume 
      readOnly: false 
     name: glusterfsvol 

Answer 1

您需要配置端点https://github.com/kubernetes/kubernetes/blob/release-1.1/examples/glusterfs/README.md，否则kubernetes不知道如何访问您的gluster集群。

Answer 2

我得和端点配置有glusterfs IP地址。

我知道张贴链接，我一直跟着它，但结果是我的第一篇文章！

Answer 3

在第一：要使用你不需要kubernetes节点上安装glusterfs-客户端GlusterFS。 Kubernetes默认具有glusterfs的批量安装选项。

要使用你需要的东西kubernetes一个glusterfs。

1. 一个工作的glusterfs服务器。 glusterfs服务器中的运行卷。我假设你有这些。如果有人不然后创建一个glusterfs服务器并启动卷使用以下命令

   $ gluster volume create <volume-name> replica 2 transport tcp \ 
       peer1:/directory \ 
       peer2:/directory \ 
       force 
   $ gluster volume start <vonlume-name> 
   $ sudo gluster volume info 
   

2. 如果这是确定的，你需要一个kubernetes端点与吊舱使用。作为一个例子，终点是这样的。

   kind: Endpoints 
   apiVersion: v1 
   metadata: 
       name: glusterfs 
   subsets: 
   - addresses: 
       - ip: peer1 
       ports: 
       - port: 1 
   - addresses: 
       - ip: peer2 
       ports: 
       - port: 1 
   

3. 然后在第三个将gfs卷挂载到一个带有终点的pod上。

    containers: 
        - name: mysql 
        image: mysql:5.6 
        ports: 
        - containerPort: 3306 
        env: 
         - name: MYSQL_ROOT_PASSWORD 
         value: password 
        volumeMounts: 
         - mountPath: /var/lib/mysql 
         name: glusterfsvol 
        volumes: 
        - glusterfs: 
         endpoints: glusterfs-cluster 
         path: <volume-name> 
        name: glusterfsvol 
   

**的路径必须卷名称与glusterfs匹配。

这一切应该正常工作。
