OpenShift实战(三)：OpenShift持久化存储Redis

1、模板定义

　　修改OpenShift自带模板

[root@master1 pv]# oc edit template redis-persistent

　　添加如下：

2、创建PV

　　编辑redis pv json文件

[root@master1 pv]# cat data_redis.json

{

  "apiVersion": "v1",

  "kind": "PersistentVolume",

  "metadata": {

    "name": "redis"

  },

  "spec": {

    "capacity": {

      "storage": "2Gi"

    },

    "accessModes": [ "ReadWriteOnce" ],

    "nfs": {

      "path": "/export/pv/data_redis",

      "server": "192.168.10.110"

    },

    "persistentVolumeReclaimPolicy": "Retain"

  }

}

　　创建对应目录

[root@master1 pv]# mkdir /export/pv/data_redis

[root@master1 pv]# chown -R nfsnobody:nfsnobody !$

[root@master1 pv]# vim /etc/exports

[root@master1 pv]# cat !$

cat /etc/exports

/export/pv/docker_registry/  *(rw,sync,all_squash)

/export/pv/data_redis/  *(rw,sync,all_squash)

[root@master1 pv]# exportfs -r

[root@master1 pv]# systemctl reload nfs-server

　　创建pv以及手动label

[root@master1 pv]# oc create -f data_redis.json

persistentvolume "redis" created

 [root@master1 pv]# oc label pv redis disktype=data_redis

persistentvolume "redis" labeled

[root@master1 pv]# oc get pv --show-labels

NAME         CAPACITY   ACCESSMODES   RECLAIMPOLICY   STATUS      CLAIM                           STORAGECLASS   REASON    AGE       LABELS

redis        2Gi        RWO           Retain          Available                                                            1m        disktype=data_redis

registrypv   100Gi      RWO           Retain          Bound       default/docker-registry-claim                            14h       disktype=registry

3、创建Redis pod

　　登录控制台-选择要部署的project-点击Add to Project - Browse Catalog

　　选择所使用的pv的label

　　点击create即可

4、查看pod
