emptyDir

重启文件还有，但是如果杀了进程，则会丢失文件
创建pod
# kubectl apply –f redis.yaml校验pod是否处于运行，并观察pod的改变
# kubectl get pod redis –-watch在其它终端上执行如下命令进入容器
# kubectl exec –it redis -- /bin/bash在shell中，进入/data/redis，然后创建文件
# cd /data/redis/
# echo Hello > test-file运行以下命令查找redis的进程
# apt-get update
# apt-get install procps
# ps aux杀掉redis进程，并观察redis pod的改变
# kill <pid>再次进入到redis的容器，查看文件是否存在。
# kubectl exec –it redis -- /bin/bash[root@k8s-01 chapter07]# cat redis.yaml 
apiVersion: v1
kind: Pod
metadata:name: redis
spec:containers:- name: redisimage: redisvolumeMounts:- name: redis-storagemountPath: /data/redisvolumes:- name: redis-storageemptyDir: {}

hostpath

只要在一个node 里面，就会找到文件
[root@k8s-01 chapter07]# cat hostpath.yaml 
apiVersion: v1
kind: Pod
metadata:name: test-pod
spec:containers:- image: nginxname: test-containervolumeMounts:- name: test-volumemountPath: /usr/share/nginxvolumes:- name: test-volumehostPath:path: /data

pv和pvc介绍

Pv: 是集群中的一段存储，由管理员提供或使用存储类动态提供。
Pvc(PersistentVolumeClaim)是用户对存储资源的请求。

nfs作为静态pv案例

nfs作为动态pv案例

安装部署存储
创建服务帐户
# kubectl create –f serviceaccount.yaml
创建集群角色并与服务帐户绑定
# kubectl create –f clusterrole.yaml
# kubectl create –f clusterrolebinding.yaml创建角色，并与服务帐户绑定
# kubectl create –f role.yaml
# kubectl create –f rolebinding.yaml创建动态存储类
# kubectl create –f class.yaml部署
# kubectl create –f deployment.yaml]
注意：以上也可以直接执行 kubectl apply –f ./nfs-de创建pv，pod及查看pvc是否通过类创建了pv并且绑定
# kubectl create –f test-claim.yaml
# kubectl create –f test-pod.yaml
# kubectl get pvc –n aishangwei文件内容

使用本地文件夹作为pv


创建文件夹，并创建文件
# mkdir /mnt/data
# echo ‘Hello from Kubernetes storage’ > /mnt/data/index.html执行如下命令创建pv,并查看创建的pv信息
# kubectl create –f pv-volume.yaml
# kubectl get pv task-pv-volume创建pvc并校验pv和pvc的信息
# kubectl create –f pvc-claim.yaml
# kubectl get pv task-pv-volume
# kubectl get pvc task-pv-claim创建pod，并引用使用的pvc
# kubectl create –f pv-pod.yaml

改变默认存储类及回收策略

查看存储类
# kubectl get storageclass2. 将存储类设置为非默认的
# kubectl patch storageclass <your-class-name> -p ‘{“metadata”:{“annotations”:{“storageclass.Kubernetes.io/is-default-class”:”false”}}}’3. 标记存储类为默认的
# kubectl patch storageclass <your-class-name> -p ‘{“metadata”:{“annotations”:{“storageclass.Kubernetes.io/is-default-class”:”true”}}}’列出持久卷
# kubectl get pv选择一个持久卷来改变它的回收策略
# kubectl patch pv <your-pv-name> -p ‘{“spec”:{“persistentVolumeReclaimPolicy”:”Retain”}}’查看设置是否正确
# kubectl get pv
