在部署高可用k8s之前，我們先來說一說單master架構和多master架構，以及多master架構中各組件工作邏輯
k8s單master架構
提示：這種單master節點的架構，通常只用於測試環境，生產環境絕對不允許；這是因爲k8s集羣master的節點是單點，一旦master節點宕機，將導致整個集羣不可用；其次單master節點apiServer是性能瓶頸；從上圖我們就可以看到，master節點所有組件和node節點中的kubelet和客戶端kubectl、dashboard都會連接apiserver，同時apiserver還要負責往etcd中更新或讀取數據，對客戶端的請求做認證、准入控制等；很顯然apiserver此時是非常忙碌的，極易成爲整個K8S集羣的瓶頸；所以不推薦在生產環境中使用單master架構；
k8s多master架構
提示：k8s高可用主要是對master節點組件高可用；其中apiserver高可用的邏輯就是通過啓用多個實例來對apiserver做高可用；apiserver從某種角度講它應該是一個有狀態服務，但爲了降低apiserver的複雜性，apiserver將數據存儲到etcd中，從而使得apiserver從有狀態服務變成了一個無狀態服務；所以高可用apiserver我們只需要啓用多個實例通過一個負載均衡器來反向代理多個apiserver，客戶端和node的節點的kubelet通過負載均衡器來連接apiserver即可；對於controller-manager、scheduler這兩個組件來說，高可用的邏輯也是啓用多個實例來實現的，不同與apiserver，這兩個組件由於工作邏輯的獨特性，一個k8s集羣中有且只有一個controller-manager和scheduler在工作，所以啓動多個實例它們必須工作在主備模式，即一個active，多個backup的模式；它們通過分佈式鎖的方式實現內部選舉，決定誰來工作，最終搶到分佈式鎖（k8s集羣endpoint）的controller-manager、scheduler成爲active狀態代表集羣controller-manager、scheduler組件工作，搶到鎖的controller-manager和scheduler會週期性的向apiserver通告自己的心跳信息，以維護自己active狀態，避免其他controller-manager、scheduler進行搶佔；其他controller-manager、scheduler收到活動的controller-manager、scheduler通過的心跳信息後自動切換爲backup狀態；一旦在規定時間備用controller-manager、scheduler沒有收到活動的controller-manager、scheduler的心跳，此時就會觸發選舉，重複上述過程；
服務器規劃
基礎環境部署
重新生成machine-id
root@k8s-deploy:~# cat /etc/machine-id 1d2aeda997bd417c838377e601fd8e10 root@k8s-deploy:~# rm -rf /etc/machine-id && dbus-uuidgen --ensure=/etc/machine-id && cat /etc/machine-id 8340419bb01397bf654c596f6443cabf root@k8s-deploy:~#
提示：如果你的環境是通過某一個虛擬機基於快照克隆出來的虛擬機，很有可能對應machine-id一樣，可以通過上述命令將對應虛擬機的machine-id修改成不一樣；注意上述命令不能再crt中同時對多個虛擬機執行，同時對多個虛擬機執行，生成的machine-id是一樣的；
內核參數優化

提示：以上操作建議在每個節點都做一下，然後把所有節點都重啓；
1、基於keepalived及haproxy部署高可用負載均衡
下載安裝keepalived和haproxy
root@k8s-ha01:~#apt update && apt install keepalived haproxy -y root@k8s-ha02:~#apt update && apt install keepalived haproxy -y
在ha01上創建/etc/keepalived/keepalived.conf

root@k8s-ha01:~#
將配置文件複製給ha02
root@k8s-ha01:~# scp /etc/keepalived/keepalived.conf ha02:/etc/keepalived/keepalived.conf keepalived.conf 100% 545 896.6KB/s 00:00 root@k8s-ha01:~#
在ha02上編輯/etc/keepalived/keepalived.conf
提示：ha02上主要修改優先級和聲明角色狀態，如上圖所示；
在ha02上啓動keepalived並設置開機啓動
root@k8s-ha02:~# systemctl start keepalived root@k8s-ha02:~# systemctl enable keepalived Synchronizing state of keepalived.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable keepalived root@k8s-ha02:~#
驗證：在ha02上查看對應vip是否存在？
在ha01啓動keepalived並設置爲開機啓動，看看對應vip是否會漂移至ha01呢？
提示：可以看到在ha01上啓動keepalived以後，對應vip就漂移到ha01上了；這是因爲ha01上的keepalived的優先級要比ha02高；
測試：停止ha01上的keepalived，看看vip是否會漂移至ha02上呢？
提示：能夠看到在ha01停止keepalived以後，對應vip會自動漂移至ha02；
驗證：用集羣其他主機ping vip看看對應是否能夠ping通呢？
root@k8s-node03:~# ping 192.168.0.111 PING 192.168.0.111 (192.168.0.111) 56(84) bytes of data. 64 bytes from 192.168.0.111: icmp_seq=1 ttl=64 time=2.04 ms 64 bytes from 192.168.0.111: icmp_seq=2 ttl=64 time=1.61 ms ^C --- 192.168.0.111 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1005ms rtt min/avg/max/mdev = 1.611/1.827/2.043/0.216 ms root@k8s-node03:~#
提示：能夠用集羣其他主機ping vip說明vip是可用的，至此keepalived配置好了；

提示：上述配置文件修改了hostname，這個主要用來指定證書中站點域名，這個必須和證書籤發時指定的域名一樣；其次是證書和私鑰的路徑以及harbor默認登錄密碼；
根據配置文件中指定路徑來創建存放harbor的數據目錄
root@harbor:/app/harbor# grep "data_volume" harbor.yml data_volume: /data root@harbor:/app/harbor# mkdir /data root@harbor:/app/harbor#
提示：爲了避免數據丟失建議這個目錄是掛載網絡文件系統，如nfs；
執行harbor部署

➜
Notary will be deprecated as of Harbor v2.6.0 and start to be removed in v2.8.0 or later.
You can use cosign for signature instead since Harbor v2.5.0.

使用我配置的密碼登錄harbor，看看是否可用正常登錄？
創建項目是否可用正常創建？
提示：可用看到我們在web網頁上能夠成功創建項目；
擴展：給harbor提供service文件，實現開機自動啓動

4、基於kubeasz部署高可用kubernetes集羣
部署節點部署環境初始化
本次我們使用kubeasz項目來部署二進制高可用k8s集羣；項目地址：https://github.com/easzlab/kubeasz；該項目使用ansible-playbook實現自動化，提供一件安裝腳本，也可以分步驟執行安裝各組件；所以部署節點首先要安裝好ansible,其次該項目使用docker下載部署k8s過程中的各種鏡像以及二進制，所以部署節點docker也需要安裝好，當然如果你的部署節點沒有安裝docker，它也會自動幫你安裝；
部署節點配置docker源
root@deploy:~# apt-get update && apt-get -y install apt-transport-https ca-certificates curl software-properties-common && curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add - && add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" && apt-get -y update
部署節點安裝ansible、docker

部署節點安裝sshpass命令⽤於同步公鑰到各k8s服務器

下載kubeasz項目安裝腳本
root@deploy:~# apt install git -y
root@deploy:~# export release=3.5.2
root@deploy:~# wget https://github.com/easzlab/kubeasz/releases/download/${release}/ezdown
編輯ezdown
提示：編輯ezdown腳本主要是定義安裝下載組件的版本，根據自己環境來定製對應版本就好；
給腳本添加執行權限

執行腳本，下載kubeasz項目及組件
root@deploy:~# ./ezdown -D
提示：執行ezdown腳本它會下載一些鏡像和二進制工具等，並將下載的二進制工具和kubeasz項目存放在/etc/kubeasz/目錄中；

提示：上述配置文件主要定義了CA和證書的過期時長、kubeconfig配置參數、k8s集羣版本、etcd數據存放目錄、運行時參數、masster證書名稱、node節點pod網段子網掩碼長度、kubelet根目錄、node節點最大pod數量、網絡插件相關參數配置以及集羣插件安裝相關配置；
提示：這裏需要注意一點，雖然我們沒有自動安裝coredns，但是這兩個變量需要設置下，如果ENABLE_LOCAL_DNS_CACHE的值是true，下面的LOCAL_DNS_CACHE就寫成對應coredns服務的IP地址；如果ENABLE_LOCAL_DNS_CACHE的值是false，後面的LOCAL_DNS_CACHE是誰的IP地址就無所謂了；
編輯系統基礎初始化主機配置
提示：註釋掉上述ex_lb和chrony表示這兩個主機我們主機定義，不需要通過kubeasz來幫我們初始化；即系統初始化，只針對master、node、etcd這三類節點來做；
準備CA和基礎環境初始化
root@deploy:/etc/kubeasz# ./ezctl setup k8s-cluster01 01
提示：執行上述命令，反饋failed都是0，表示指定節點的初始化環境準備就緒，接下來我們就可以進行第二步部署etcd節點；
部署etcd集羣
root@deploy:/etc/kubeasz# ./ezctl setup k8s-cluster01 02
提示：這裏報錯說不能/usr/bin/python沒有找到，導致不能獲取到/etc/kubeasz/clusters/k8s-cluster01/ssl/etcd-csr.json信息；
解決辦法，在部署節點上將/usr/bin/python3軟連接至/usr/bin/python；
root@deploy:/etc/kubeasz# ln -sv /usr/bin/python3 /usr/bin/python '/usr/bin/python' -> '/usr/bin/python3' root@deploy:/etc/kubeasz#
再次執行上述部署步驟
驗證etcd集羣是否正常？

配置harbor鏡像倉庫域名解析-公司有DNS服務器進⾏域名解析
提示：編輯/etc/kubeasz/roles/containerd/tasks/main.yml文件在block配置段裏面任意找個地方將其上述任務加上即可；
編輯/etc/kubeasz/roles/containerd/templates/config.toml.j2⾃定義containerd配置⽂件模板；
提示：這個參數在ubuntu2204上一定要改成true；否者會出現k8spod不斷重啓的現象；一般和kubelet保持一致；
提示：這裏可以根據自己的環境來配置相應的鏡像加速地址；
私有https/http鏡像倉庫配置下載認證
提示：如果你的鏡像倉庫是一個私有（不是公開的倉庫，即下載鏡像需要用戶名和密碼的倉庫）https/http倉庫，添加上述配置containerd在下載對應倉庫中的鏡像，會拿這裏配置的用戶名密碼去下載鏡像；
配置nerdctl客戶端
提示：編輯/etc/kubeasz/roles/containerd/tasks/main.yml文件加上nerdctl配置相關任務；
在部署節點準備nerdctl工具二進制文件和依賴文件、配置文件

提示：這裏說一下kubeasz部署master和node節點時，都會執行kube-lb這個role；這個role就是一個nginx，主要作用是反向代理master apiserver，即訪問本地127.0.0.1：6443，對應訪問會被反向代理至後端多個master apiserver，即便是在master本地也會代理；這樣做的主要原因是分擔外部負載均衡器的壓力同時實現多master高可用；
如master上的kube-lb的配置文件
執行部署node節點
root@deploy:/etc/kubeasz# ./ezctl setup k8s-cluster01 05
驗證：在部署節點獲取node信息，看看是否能夠正常獲取到？
root@k8s-deploy:/etc/kubeasz# kubectl get nodes NAME STATUS ROLES AGE VERSION 192.168.0.31 Ready,SchedulingDisabled master 5m34s v1.26.1 192.168.0.32 Ready,SchedulingDisabled master 5m34s v1.26.1 192.168.0.34 Ready node 49s v1.26.1 192.168.0.35 Ready node 49s v1.26.1 root@k8s-deploy:/etc/kubeasz#
提示：能夠通過kubectl獲取到node信息，就表示對應master和node部署完成，至少master節點和node節點該有的組件都正常工作；至此k8s集羣master節點和node節點的部署就完成了，接下部署calico網絡插件；
部署網絡組件calico
部署calico組件配置
提示：我們可以根據自己的環境修改calico部署配置；

提示：能夠在master節點和node節點通過calicoctl 命令查詢到其他節點信息，說明calico插件就部署好了；
驗證pod通信
複製部署節點上/root/.kube/config文件至master節點
root@k8s-deploy:/etc/kubeasz# scp /root/.kube/config 192.168.0.31:/root/.kube/ config 100% 6196 3.8MB/s 00:00 root@k8s-deploy:/etc/kubeasz#
提示：這一步不是必須的，如果你要在master節點使用kubectl命令來管理集羣，就把配置文件複製過去；
修改/root/.kube/config文件中apiserver地址爲外部負載均衡地址
測試kubectl命令是否正常可用？
提示：如果能夠正常執行kubectl命令，說明外部負載均衡器沒有問題；
創建測試pod
root@k8s-master01:~# kubectl run test --image=alpine sleep 36000 pod/test created root@k8s-master01:~# kubectl run test1 --image=alpine sleep 36000 pod/test1 created root@k8s-master01:~# kubectl run test2 --image=alpine sleep 36000 pod/test2 created root@k8s-master01:~#
查看pod IP網絡地址

進入任意測試pod，ping其他兩個pod，看看是否能夠正常ping通？是否可以正常訪問互聯網？
提示：可以看到pod和pod之間可以正常跨主機通信，也可以正常訪問到外網，這裏需要注意，現在集羣還沒有部署coredns，所以這裏直接ping www.baidu.com是無法正常解析的；

提示：上面我們使用的是kubeasz來更行k8s集羣master和node；我們也可以手動更新；
手動更新
方法1：將⼆進制⽂件同步到其它路徑，修改service⽂件加載新版本⼆進制，即⽤新版本替換舊版本；
方法2：關閉源服務、替換⼆進制⽂件然後啓動服務，即直接替換舊版本；

導入集羣
添加集羣的方式有兩種，一種是agent，一種是kubeconfig；agent這種方式需要在k8s上額外運行一個pod來作爲agent；
agent方式導入集羣
提示：把上述命令在k8s集羣上執行下就好；
kubeconfig方式導入集羣
提示：需要將製作好的kubeconfig文件內容直接粘貼進來即可；
返回首頁查看集羣列表
提示：kuboard它可用管理多個集羣；
選擇使用集羣的身份
查看集羣概要信息
好了，第三方dashboard kuboard就部署好了，後面我們管理k8s集羣就可用在kuboard上面點點；如果需要卸載kuboard ，只需要在k8s上將部署清單delete一下即可；kubectl delete -f kuboard-all-in-one.yaml；
