基于kubeasz部署高可用k8s集群

　　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

root@deploy:~# cat /etc/sysctl.conf
net.ipv4.ip_forward=1
vm.max_map_count=262144
kernel.pid_max=4194303
fs.file-max=1000000
net.ipv4.tcp_max_tw_buckets=6000
net.netfilter.nf_conntrack_max=2097152
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
vm.swappiness=0

　　系统资源限制

root@deploy:~# tail -10 /etc/security/limits.conf
root    soft    core            unlimited
root    hard    core            unlimited
root    soft    nproc           1000000

root@deploy:~# 

　　内核模块挂载

root@deploy:~# cat /etc/modules-load.d/modules.conf
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

　　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

1 2	`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 {
     acassen
   }

    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

　　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

　　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

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

　　部署节点安装ansible、docker

　　提示：上述配置文件主要定义了CA和证书的过期时长、kubeconfig配置参数、k8s集群版本、etcd数据存放目录、运行时参数、masster证书名称、node节点pod网段子网掩码长度、kubelet根目录、node节点最大pod数量、网络插件相关参数配置以及集群插件安装相关配置；

　　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自己定义，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

1	`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

1	`root@deploy:/etc/kubeasz# ./ezctl setup k8s-cluster01 02`

　　提示：这里报错说/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？

root@k8s-etcd01:~# export NODE_IPS="192.168.0.37 192.168.0.38 192.168.0.39"   
root@k8s-etcd01:~# for ip in ${NODE_IPS}; do ETCDCTL_API=3 /usr/local/bin/etcdctl --endpoints=https://${ip}:2379 --cacert=/etc/kubernetes/ssl/ca.pem --cert=/etc/kubernetes/ssl/etcd.pem --key=/etc/kubernetes/ssl/etcd-key.pem endpoint health; done

https://192.168.0.39:2379 is healthy: successfully committed proposal: took = 32.747586ms
root@k8s-etcd01:~# 

　　提示：能够看到上面的健康状态成功，表示etcd集群服务正常；

　　部署容器运行时containerd

　　验证基础容器镜像

root@deploy:/etc/kubeasz# grep SANDBOX_IMAGE ./clusters/* -R
./clusters/k8s-cluster01/config.yml:SANDBOX_IMAGE: "harbor.ik8s.cc/baseimages/pause:3.9"
root@deploy:/etc/kubeasz#

　　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：能够在master或node节点上正常使用nerdctl上传镜像到harbor，从harbor下载镜像到本地，说明我们部署的容器运行时containerd就没有问题了；接下就可以部署k8s master节点；

　　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

1	`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？

root@k8s-deploy:/etc/kubeasz# kubectl get nodes
NAME           STATUS                     ROLES    AGE     VERSION
192.168.0.31   Ready,SchedulingDisabled   master   5m34s   v1.26.1

192.168.0.35   Ready                      node     49s     v1.26.1
root@k8s-deploy:/etc/kubeasz# 

　　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；

　　部署网络组件calico

　　部署calico组件配置

　　提示：我们可以根据自己的环境修改calico部署配置；

　　查看calico所需镜像

　　验证部署节点本地镜像

　　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:~# 

　　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；

　　集群节点伸缩管理

　　添加node节点

1	`root@k8s-deploy:/etc/kubeasz# ./ezctl add-node k8s-cluster01 192.168.0.36`

　　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；

　　将coredns及dashboard部署至kubernetes集群

　　部署k8s内部域名解析服务coredns

　　访问kuboard

　　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；

　　部署第三方dashboard kubesphere

　　提前准备存储类相关部署清单

　　在NFS上准备数据目录

root@harbor:~# mkdir -p /data/volumes
root@harbor:~# cat /etc/exports 
# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#
/data/k8sdata/kuboard *(rw,no_root_squash)
/data/volumes *(rw,no_root_squash)
root@harbor:~# exportfs -av
exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/data/k8sdata/kuboard".
  Assuming default behaviour ('no_subtree_check').
  NOTE: this default has changed since nfs-utils version 1.0.x
 
exportfs: /etc/exports [2]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/data/volumes".
  Assuming default behaviour ('no_subtree_check').
  NOTE: this default has changed since nfs-utils version 1.0.x
 
exporting *:/data/volumes

　　应用上述授权、存储类、NFS提供者清单

root@k8s-master01:~/KubeSphere/1.nfs-stroageclass-cases# kubectl apply -f .
namespace/nfs created
serviceaccount/nfs-client-provisioner created
clusterrole.rbac.authorization.k8s.io/nfs-client-provisioner-runner created
clusterrolebinding.rbac.authorization.k8s.io/run-nfs-client-provisioner created
role.rbac.authorization.k8s.io/leader-locking-nfs-client-provisioner created
rolebinding.rbac.authorization.k8s.io/leader-locking-nfs-client-provisioner created
storageclass.storage.k8s.io/nfs-csi created
deployment.apps/nfs-client-provisioner created
root@k8s-master01:~/KubeSphere/1.nfs-stroageclass-cases# 

　　验证：查看对应pod是否正常运行？

　　验证存储类是否正常创建

　　编辑cluster-configuration.yaml，启用插件

　　启用logging

　　提示：除了在部署前修改cluster-configuration.yaml文件来启用各种插件，也可以在部署后使用admin用户登录控制台，在平台管理，选集权管理，定制资源定义，在搜索栏里输入clusterconfiguration，点击搜索结果查看详细页面；在自定义资源中，点击kk-installer右侧编辑YAML；

　　应用kubesphere-installer.yaml安装清单

root@k8s-master01:~/KubeSphere# kubectl apply -f kubesphere-installer.yaml 
customresourcedefinition.apiextensions.k8s.io/clusterconfigurations.installer.kubesphere.io created
namespace/kubesphere-system created
serviceaccount/ks-installer created
clusterrole.rbac.authorization.k8s.io/ks-installer created
clusterrolebinding.rbac.authorization.k8s.io/ks-installer created
deployment.apps/ks-installer created
root@k8s-master01:~/KubeSphere#

　　应用cluster-configuration.yaml集群配置清单

root@k8s-master01:~/KubeSphere# kubectl apply -f cluster-configuration.yaml 
clusterconfiguration.installer.kubesphere.io/ks-installer created
root@k8s-master01:~/KubeSphere# 

　　查看安装过程⽇志信息

1	`root@k8s-master01:~/KubeSphere# kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f`

　　验证：查看pods是否正常运行
