在部署高可用k8s之前，我们先来说一说单master架构和多master架构，以及多master架构中各组件工作逻辑
k8s单master架构
提示：这种单master节点的架构，通常只用于测试环境，生产环境绝对不允许；这是因为k8s集群master的节点是单点，一旦master节点宕机，将导致整个集群不可用；其次单master节点apiServer是性能瓶颈；从上图我们就可以看到，master节点所有组件和node节点中的kubelet和客户端kubectl、dashboard都会连接apiserver，同时apiserver还要负责往etcd中更新或读取数据，对客户端的请求做认证、准入控制等；很显然apiserver此时是非常忙碌的，极易成为整个K8S集群的瓶颈；所以不推荐在生产环境中使用单master架构；
k8s多master架构
提示：k8s高可用主要是对master节点组件高可用；其中apiserver高可用的逻辑就是通过启用多个实例来对apiserver做高可用；apiserver从某种角度讲它应该是一个有状态服务，但为了降低apiserver的复杂性，apiserver将数据存储到etcd中，从而使得apiserver从有状态服务变成了一个无状态服务；所以高可用apiserver我们只需要启用多个实例通过一个负载均衡器来反向代理多个apiserver，客户端和node的节点的kubelet通过负载均衡器来连接apiserver即可；对于controller-manager、scheduler这两个组件来说，高可用的逻辑也是启用多个实例来实现的，不同与apiserver，这两个组件由于工作逻辑的独特性，一个k8s集群中有且只有一个controller-manager和scheduler在工作，所以启动多个实例它们必须工作在主备模式，即一个active，多个backup的模式；它们通过分布式锁的方式实现内部选举，决定谁来工作，最终抢到分布式锁（k8s集群endpoint）的controller-manager、scheduler成为active状态代表集群controller-manager、scheduler组件工作，抢到锁的controller-manager和scheduler会周期性的向apiserver通告自己的心跳信息，以维护自己active状态，避免其他controller-manager、scheduler进行抢占；其他controller-manager、scheduler收到活动的controller-manager、scheduler通过的心跳信息后自动切换为backup状态；一旦在规定时间备用controller-manager、scheduler没有收到活动的controller-manager、scheduler的心跳，此时就会触发选举，重复上述过程；
服务器规划
基础环境部署
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：如果你的环境是通过某一个虚拟机基于快照克隆出来的虚拟机，很有可能对应machine-id一样，可以通过上述命令将对应虚拟机的machine-id修改成不一样；注意上述命令不能再crt中同时对多个虚拟机执行，同时对多个虚拟机执行，生成的machine-id是一样的；
内核参数优化

提示：以上操作建议在每个节点都做一下，然后把所有节点都重启；
1、基于keepalived及haproxy部署高可用负载均衡
下载安装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上创建/etc/keepalived/keepalived.conf
root@k8s-ha01:~# cat /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {

}
virtual_ipaddress {
192.168.0.111 dev ens160 label ens160:0
}
}
root@k8s-ha01:~#
将配置文件复制给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上编辑/etc/keepalived/keepalived.conf
提示：ha02上主要修改优先级和声明角色状态，如上图所示；
在ha02上启动keepalived并设置开机启动
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:~#
验证：在ha02上查看对应vip是否存在？
在ha01启动keepalived并设置为开机启动，看看对应vip是否会漂移至ha01呢？
提示：可以看到在ha01上启动keepalived以后，对应vip就漂移到ha01上了；这是因为ha01上的keepalived的优先级要比ha02高；
测试：停止ha01上的keepalived，看看vip是否会漂移至ha02上呢？
提示：能够看到在ha01停止keepalived以后，对应vip会自动漂移至ha02；
验证：用集群其他主机ping vip看看对应是否能够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：能够用集群其他主机ping vip说明vip是可用的，至此keepalived配置好了；

提示：上述配置文件修改了hostname，这个主要用来指定证书中站点域名，这个必须和证书签发时指定的域名一样；其次是证书和私钥的路径以及harbor默认登录密码；
根据配置文件中指定路径来创建存放harbor的数据目录
root@harbor:/app/harbor# grep "data_volume" harbor.yml data_volume: /data root@harbor:/app/harbor# mkdir /data root@harbor:/app/harbor#
提示：为了避免数据丢失建议这个目录是挂载网络文件系统，如nfs；
执行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.

通过上述测试，可以看到我们部署的harbor仓库能够实现上传和下载images；至此基于商用公司的免费证书搭建https harbor仓库就完成了；
4、基于kubeasz部署高可用kubernetes集群
部署节点部署环境初始化
本次我们使用kubeasz项目来部署二进制高可用k8s集群；项目地址：https://github.com/easzlab/kubeasz；该项目使用ansible-playbook实现自动化，提供一件安装脚本，也可以分步骤执行安装各组件；所以部署节点首先要安装好ansible,其次该项目使用docker下载部署k8s过程中的各种镜像以及二进制，所以部署节点docker也需要安装好，当然如果你的部署节点没有安装docker，它也会自动帮你安装；
部署节点配置docker源

下载kubeasz项目安装脚本
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
编辑ezdown
提示：编辑ezdown脚本主要是定义安装下载组件的版本，根据自己环境来定制对应版本就好；
给脚本添加执行权限

提示：这里需要注意一点，虽然我们没有自动安装coredns，但是这两个变量需要设置下，如果ENABLE_LOCAL_DNS_CACHE的值是true，下面的LOCAL_DNS_CACHE就写成对应coredns服务的IP地址；如果ENABLE_LOCAL_DNS_CACHE的值是false，后面的LOCAL_DNS_CACHE是谁的IP地址就无所谓了；
编辑系统基础初始化主机配置
提示：注释掉上述ex_lb和chrony表示这两个主机我们主机定义，不需要通过kubeasz来帮我们初始化；即系统初始化，只针对master、node、etcd这三类节点来做；
准备CA和基础环境初始化
root@deploy:/etc/kubeasz# ./ezctl setup k8s-cluster01 01
提示：执行上述命令，反馈failed都是0，表示指定节点的初始化环境准备就绪，接下来我们就可以进行第二步部署etcd节点；
部署etcd集群
root@deploy:/etc/kubeasz# ./ezctl setup k8s-cluster01 02
提示：这里报错说不能/usr/bin/python没有找到，导致不能获取到/etc/kubeasz/clusters/k8s-cluster01/ssl/etcd-csr.json信息；
解决办法，在部署节点上将/usr/bin/python3软连接至/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#
再次执行上述部署步骤
验证etcd集群是否正常？

部署容器运行时containerd
验证基础容器镜像

配置harbor镜像仓库域名解析-公司有DNS服务器进⾏域名解析
提示：编辑/etc/kubeasz/roles/containerd/tasks/main.yml文件在block配置段里面任意找个地方将其上述任务加上即可；
编辑/etc/kubeasz/roles/containerd/templates/config.toml.j2⾃定义containerd配置⽂件模板；
提示：这个参数在ubuntu2204上一定要改成true；否者会出现k8spod不断重启的现象；一般和kubelet保持一致；
提示：这里可以根据自己的环境来配置相应的镜像加速地址；
私有https/http镜像仓库配置下载认证
提示：如果你的镜像仓库是一个私有（不是公开的仓库，即下载镜像需要用户名和密码的仓库）https/http仓库，添加上述配置containerd在下载对应仓库中的镜像，会拿这里配置的用户名密码去下载镜像；
配置nerdctl客户端
提示：编辑/etc/kubeasz/roles/containerd/tasks/main.yml文件加上nerdctl配置相关任务；
在部署节点准备nerdctl工具二进制文件和依赖文件、配置文件

提示：这里说一下kubeasz部署master和node节点时，都会执行kube-lb这个role；这个role就是一个nginx，主要作用是反向代理master apiserver，即访问本地127.0.0.1：6443，对应访问会被反向代理至后端多个master apiserver，即便是在master本地也会代理；这样做的主要原因是分担外部负载均衡器的压力同时实现多master高可用；
如master上的kube-lb的配置文件
执行部署node节点
root@deploy:/etc/kubeasz# ./ezctl setup k8s-cluster01 05
验证：在部署节点获取node信息，看看是否能够正常获取到？

提示：能够通过kubectl获取到node信息，就表示对应master和node部署完成，至少master节点和node节点该有的组件都正常工作；至此k8s集群master节点和node节点的部署就完成了，接下部署calico网络插件；

提示：能够在master节点和node节点通过calicoctl 命令查询到其他节点信息，说明calico插件就部署好了；
验证pod通信
复制部署节点上/root/.kube/config文件至master节点
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：这一步不是必须的，如果你要在master节点使用kubectl命令来管理集群，就把配置文件复制过去；
修改/root/.kube/config文件中apiserver地址为外部负载均衡地址
测试kubectl命令是否正常可用？
提示：如果能够正常执行kubectl命令，说明外部负载均衡器没有问题；
创建测试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网络地址
root@k8s-master01:~# kubectl get pods -o wide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES test 1/1 Running 0 63s 10.200.209.1 192.168.0.35test1 1/1 Running 0 58s 10.200.209.2 192.168.0.35 test2 1/1 Running 0 47s 10.200.211.129 192.168.0.34 root@k8s-master01:~#
进入任意测试pod，ping其他两个pod，看看是否能够正常ping通？是否可以正常访问互联网？
提示：可以看到pod和pod之间可以正常跨主机通信，也可以正常访问到外网，这里需要注意，现在集群还没有部署coredns，所以这里直接ping www.baidu.com是无法正常解析的；

提示：上面我们使用的是kubeasz来更行k8s集群master和node；我们也可以手动更新；
手动更新
方法1：将⼆进制⽂件同步到其它路径，修改service⽂件加载新版本⼆进制，即⽤新版本替换旧版本；
方法2：关闭源服务、替换⼆进制⽂件然后启动服务，即直接替换旧版本；

提示：默认用户名和密码是admin/Kuboard123
导入集群
添加集群的方式有两种，一种是agent，一种是kubeconfig；agent这种方式需要在k8s上额外运行一个pod来作为agent；
agent方式导入集群
提示：把上述命令在k8s集群上执行下就好；
kubeconfig方式导入集群
提示：需要将制作好的kubeconfig文件内容直接粘贴进来即可；
返回首页查看集群列表
提示：kuboard它可用管理多个集群；
选择使用集群的身份
查看集群概要信息
好了，第三方dashboard kuboard就部署好了，后面我们管理k8s集群就可用在kuboard上面点点；如果需要卸载kuboard ，只需要在k8s上将部署清单delete一下即可；kubectl delete -f kuboard-all-in-one.yaml；
