示例1:測試創(chuàng)建PVC 自動創(chuàng)建PV
longhorn數(shù)據(jù)存儲位置及自定義資源

前言：

前面介紹的PV、PVC完成了存儲類型和Pod掛載的解耦，開發(fā)人員直接使用PVC，而Volume存儲系統(tǒng)的PV由管理員維護(hù)，但隨之帶來的問題，開發(fā)人員使用PVC之前，需要系統(tǒng)管理員提前手動創(chuàng)建PV，而隨著pod的不斷增多，系統(tǒng)管理員的工作會變得重復(fù)和繁瑣，靜態(tài)供給方式這并不符合自動化運(yùn)維的趨勢，隨之應(yīng)運(yùn)而生的Storageclass 動態(tài)預(yù)配存儲空間，它的作用就是創(chuàng)建PV的模板,解決了PV的自動創(chuàng)建，備份等擴(kuò)展功能.

Storageclass 簡介

簡稱SC;PV和PVC都可屬于某個(gè)特定的SC;
創(chuàng)建PV的模板:可以將某個(gè)存儲服務(wù)與SC關(guān)聯(lián)起來，并且將該存儲服務(wù)的管理接口提供給SC，從而讓SC能夠在存儲服務(wù)上CRUD(create、Read.Update和Delete)存儲單元;因而，在同一個(gè)SC上聲明PVC時(shí)，若無現(xiàn)存可匹配的PV，則SC能夠調(diào)用管理接口直接創(chuàng)建出一個(gè)符合PVC聲明的需求的PV來。這種PV的提供機(jī)制，就稱為Dynamic Provision.

具體來說，StorageClass會定義一下兩部分：

PV的屬性，比如存儲的大小、類型等；
創(chuàng)建這種PV需要使用到的存儲插件，比如Ceph等；

有了這兩部分信息，Kubernetes就能夠根據(jù)用戶提交的PVC，找到對應(yīng)的StorageClass，然后Kubernetes就會調(diào)用 StorageClass聲明的存儲插件，創(chuàng)建出需要的PV。

這里需要注意的是這么多種存儲系統(tǒng)并不是所有的存儲系統(tǒng)都支持StorageClass,它需要你的存儲系統(tǒng)提供某種接口來讓controller可以調(diào)用并傳遞進(jìn)去PVC的參數(shù)去創(chuàng)建PV

常用字段:

StorageClass資源的期望狀態(tài)直接與apiversion、kind和metadata定義于同一級別而無須嵌套于spec字段中，它支持使用的字段包括如下幾個(gè)

allowVolumeExpansion <boolean>:是否支持存儲卷空間擴(kuò)展功能;
allowedTopologies <[]0bject>:定義可以動態(tài)配置存儲卷的節(jié)點(diǎn)拓?fù)?，僅啟用了卷調(diào)度功能的服務(wù)器才會用到該字段;每個(gè)卷插件都有自己支持的拓?fù)湟?guī)范，空的拓?fù)溥x擇器表示無拓?fù)湎拗?
provisioner <strinp>:必選字段，用于指定存儲服務(wù)方(provisioner，或稱為預(yù)備器)，存儲類要依賴該字段值來判定要使用的存儲插件以便適配到目標(biāo)存儲系統(tǒng);kubernetes內(nèi)建支持許多的Provisioner，它們的名字都以kubernetes.io/為前綴，例如kubernetes.io/glusterfs等;
parameters <map[string]stringp: 定義連接至指定的Provisioner類別下的某特定存儲時(shí)需要使用的各相關(guān)參數(shù);不同Provisioner的可用的參數(shù)各不相同;
reclaimPolicy <strinp:由當(dāng)前存儲類動態(tài)創(chuàng)建約PV資源的默認(rèn)回收策路，可用值為Delete(默認(rèn))和Retain兩個(gè);但那些靜態(tài)FV的回收策略則取決于它們自身的定義;
volumeBindingMlode <string>:定義如何為PVC完成預(yù)配和綁定，默認(rèn)值為VolumeBindingImmediate;該字段僅在啟用了存儲卷調(diào)度功能時(shí)才能生效;
mountoptions<[]string>:由當(dāng)前類動態(tài)創(chuàng)建的PV資源的默認(rèn)掛載選項(xiàng)列表。

Longhorn Storageclass插件提供更多的擴(kuò)展功能

官方文檔: https://longhorn.io

Longhorn極大地提升了開發(fā)人員和ITOps的效率，僅需點(diǎn)擊一下鼠標(biāo)，即可輕松實(shí)現(xiàn)持久化存儲，并且無需為專有解決方案支付昂貴的費(fèi)用。除此之外，Longhorn減少了管理數(shù)據(jù)及操作環(huán)境所需的資源，從而幫助企業(yè)更加專注且快速地交付代碼及應(yīng)用程序。

Longhorn依舊秉承Rancher 100%開源的產(chǎn)品理念，它是一個(gè)使用微服務(wù)構(gòu)建的分布式塊存儲項(xiàng)目。2019年，Longhorn發(fā)布Beta版本，并于同年10月作為沙箱（Sandbox）項(xiàng)目捐獻(xiàn)給CNCF。Longhorn受到了開發(fā)者們的廣泛關(guān)注，成千上萬名用戶對其進(jìn)行了壓力測試，并提供了極為寶貴的反饋意見。

Longhorn的GA版本提供了一系列功能豐富的企業(yè)級存儲功能，包括：

自動配置，快照，備份和恢復(fù)
零中斷卷擴(kuò)容
具有定義的RTO和RPO的跨集群災(zāi)難恢復(fù)卷
在不影響卷的情況下實(shí)時(shí)升級
全功能的Kubernetes CLI集成和獨(dú)立的用戶界面
