nacos-peer-finder-plugin
這個(gè)鏡像唯一的作用是安裝 peer-finder插件相關(guān)的腳本到指定目錄（plugins/peer-finder/），結(jié)束后就死亡。peer-finder插件的功能是輪詢（1秒）指定的k8s service ，如果service下面的pod地址列表發(fā)生變化，則重新寫入cluster.conf文件，以便實(shí)現(xiàn)nacos的動(dòng)態(tài)擴(kuò)容。

nacos-server
nacos本體鏡像，鏡像啟動(dòng)時(shí)，除了啟動(dòng)自身的服務(wù)外，還會(huì)同時(shí)調(diào)用peer-finder-plugin-install 安裝好的腳本啟動(dòng)peer-finder。
容器運(yùn)行原理
Nacos集群節(jié)點(diǎn)信息保存在cluster.conf文件中，在k8s環(huán)境下不再需要手動(dòng)去更改cluster.conf文件來(lái)維護(hù)集群，必須使用k8s的機(jī)制去完成自動(dòng)擴(kuò)縮容。其實(shí)是peer-finder-plugin 和 上面說(shuō)的自動(dòng)輪詢cluster.conf機(jī)制來(lái)達(dá)到的。
通過(guò)Helm使用官方的chart包部署的nacos集群，每一個(gè)pod有兩個(gè)容器：
- peer-finder-plugin-install : 是一個(gè)initContainers ，這個(gè)鏡像唯一的作用是安裝 peer-finder插件相關(guān)的腳本到指定目錄（plugins/peer-finder/），結(jié)束后就死亡。
- nacos-cluster：nacos本體鏡像，鏡像啟動(dòng)時(shí)，除了啟動(dòng)自身的服務(wù)外，還會(huì)同時(shí)調(diào)用peer-finder-plugin-install 安裝好的腳本啟動(dòng)peer-finder（nacos dockerfile）
peer-finder這個(gè)插件很簡(jiǎn)單，使用go語(yǔ)言寫的一個(gè)定時(shí)輪詢的程序，
peer-finder輪詢（1秒）指定的k8s service ，如果service下面的pod地址列表發(fā)生變化，則重新寫入cluster.conf文件。這里的k8s service就必須是headless類型的了，因?yàn)橹挥薪馕鰄eadless提供的域名，才能獲取所有pod的地址列表。
pod啟動(dòng)順序如下：

nacos集群原理
客戶端與集群的交互
首先需要聲明的是Nacos Cluster雖然內(nèi)部使用了Raft協(xié)議，但是對(duì)于Nacos客戶端，Cluster實(shí)例是無(wú)狀態(tài)的?？蛻舳伺渲眉旱刂酚袃煞N方式：
- 1.通過(guò)配置serverAddr列表，客戶端將訪問(wèn)集群時(shí)，隨機(jī)從列表中選擇一個(gè)實(shí)例訪問(wèn)：
當(dāng)然，一般情況下我們并不會(huì)直接配置Nacos實(shí)例的IP，可用用域名，以便能動(dòng)態(tài)發(fā)現(xiàn)。
- 2.通過(guò)Properties配置endpoint，定時(shí)訪問(wèn)，感知集群變化，并隨機(jī)從接口返回的列表中選擇一個(gè)實(shí)例訪問(wèn)，客戶端會(huì)與Endpoint創(chuàng)建LONG PULL。
- endpoint環(huán)境隔離最佳實(shí)踐
節(jié)點(diǎn)發(fā)現(xiàn)
只需要在部署Nacos 實(shí)例時(shí)，在conf/cluster.conf 中把自己和集群內(nèi)其它實(shí)例的地址整合到一起即可，cluster.conf文件可以是這樣：
ip1:8848 ip2:8848 ip3:8848這樣就構(gòu)成了集群。Nacos實(shí)例會(huì)輪詢cluster.conf 文件，以保證集群在有新的實(shí)例加入時(shí)能相互發(fā)現(xiàn)以實(shí)現(xiàn)實(shí)例的擴(kuò)縮容，具體代碼實(shí)現(xiàn)在（com.alibaba.nacos.naming.cluster.ServerListManager.ServerListUpdater）。

nacos端口
nacos默認(rèn)使用8848對(duì)外提供服務(wù)，7848 用于節(jié)點(diǎn)直接的通信，例如選舉leader。
解決K8S/openshift等限制以root賬戶運(yùn)行問(wèn)題
如果K8S/openshift限制以root賬戶運(yùn)行，則nacos中的tomcat會(huì)啟動(dòng)失敗，在 /home/nacos/logs/start.out 中記錄以下錯(cuò)誤：
