二进制安装Kubernetes（k8s） v1.27.1 IPv4/IPv6双栈 可脱离互联网

二进制安装Kubernetes（k8s） v1.27.1 IPv4/IPv6双栈 可脱离互联网

https://github.com/cby-chen/Kubernetes 开源不易，帮忙点个star，谢谢了

介绍

kubernetes（k8s）二进制高可用安装部署，支持IPv4+IPv6双栈。

我使用IPV6的目的是在公网进行访问，所以我配置了IPV6静态地址。

若您没有IPV6环境，或者不想使用IPv6，不对主机进行配置IPv6地址即可。

不配置IPV6，不影响后续，不过集群依旧是支持IPv6的。为后期留有扩展可能性。

若不要IPv6 ，不给网卡配置IPv6即可，不要对IPv6相关配置删除或操作，否则会出问题。

强烈建议在Github上查看文档 ！！！

Github出问题会更新文档，并且后续尽可能第一时间更新新版本文档 ！！！

2.3.3将组件发送至其他k8s节点

Master='k8s-master02 k8s-master03'
Work='k8s-node01 k8s-node02'

for NODE in $Master; do echo $NODE; scp /usr/local/bin/kube{let,ctl,-apiserver,-controller-manager,-scheduler,-proxy} $NODE:/usr/local/bin/; scp /usr/local/bin/etcd* $NODE:/usr/local/bin/; done

for NODE in $Work; do     scp /usr/local/bin/kube{let,-proxy} $NODE:/usr/local/bin/ ; done

mkdir -p /opt/cni/bin

2.3创建证书相关文件

mkdir pki
cd pki
cat > admin-csr.json  ca-config.json  etcd-ca-csr.json   front-proxy-ca-csr.json   kubelet-csr.json   manager-csr.json  apiserver-csr.json  ca-csr.json    etcd-csr.json  front-proxy-client-csr.json   kube-proxy-csr.json   scheduler-csr.json  bootstrap.secret.yaml  coredns.yaml  metrics-server.yaml 

3.相关证书生成

# master01节点下载证书生成工具
# wget "https://github.com/cloudflare/cfssl/releases/download/v1.6.1/cfssl_1.6.2_linux_amd64" -O /usr/local/bin/cfssl
# wget "https://github.com/cloudflare/cfssl/releases/download/v1.6.1/cfssljson_1.6.2_linux_amd64" -O /usr/local/bin/cfssljson

# 软件包内有
cp cfssl /usr/local/bin/cfssl
cp cfssljson /usr/local/bin/cfssljson

chmod +x /usr/local/bin/cfssl /usr/local/bin/cfssljson

3.1.生成etcd证书

特别说明除外，以下操作在所有master节点操作

3.1.1所有master节点创建证书存放目录

mkdir /etc/etcd/ssl -p

3.1.2master01节点生成etcd证书

cd pki
# 生成etcd证书和etcd证书的key（如果你觉得以后可能会扩容，可以在ip那多写几个预留出来）
# 若没有IPv6 可删除可保留 
cfssl gencert -initca etcd-ca-csr.json | cfssljson -bare /etc/etcd/ssl/etcd-ca
cfssl gencert 
   -ca=/etc/etcd/ssl/etcd-ca.pem 
   -ca-key=/etc/etcd/ssl/etcd-ca-key.pem 
   -config=ca-config.json 
   -hostname=127.0.0.1,k8s-master01,k8s-master02,k8s-master03,192.168.0.31,192.168.0.32,192.168.0.33,fc00:43f4:1eea:1::10,fc00:43f4:1eea:1::20,fc00:43f4:1eea:1::30,::1 
   -profile=kubernetes 
   etcd-csr.json | cfssljson -bare /etc/etcd/ssl/etcd

3.1.3将证书复制到其他节点

Master='k8s-master02 k8s-master03'
for NODE in $Master; do ssh $NODE "mkdir -p /etc/etcd/ssl"; for FILE in etcd-ca-key.pem  etcd-ca.pem  etcd-key.pem  etcd.pem; do scp /etc/etcd/ssl/${FILE} $NODE:/etc/etcd/ssl/${FILE}; done; done

3.2.生成k8s相关证书

特别说明除外，以下操作在所有master节点操作

3.2.1所有k8s节点创建证书存放目录

mkdir -p /etc/kubernetes/pki

3.2.2master01节点生成k8s证书

cfssl gencert -initca ca-csr.json | cfssljson -bare /etc/kubernetes/pki/ca

# 生成一个根证书 ，多写了一些IP作为预留IP，为将来添加node做准备
# 10.96.0.1是service网段的第一个地址，需要计算，192.168.0.36为高可用vip地址
# 若没有IPv6 可删除可保留 

cfssl gencert   
-ca=/etc/kubernetes/pki/ca.pem   
-ca-key=/etc/kubernetes/pki/ca-key.pem   
-config=ca-config.json   
-hostname=10.96.0.1,192.168.0.36,127.0.0.1,kubernetes,kubernetes.default,kubernetes.default.svc,kubernetes.default.svc.cluster,kubernetes.default.svc.cluster.local,x.oiox.cn,k.oiox.cn,l.oiox.cn,o.oiox.cn,192.168.0.31,192.168.0.32,192.168.0.33,192.168.0.34,192.168.0.35,192.168.0.36,192.168.0.37,192.168.0.38,192.168.0.39,192.168.1.70,fc00:43f4:1eea:1::10,fc00:43f4:1eea:1::20,fc00:43f4:1eea:1::30,fc00:43f4:1eea:1::40,fc00:43f4:1eea:1::50,fc00:43f4:1eea:1::60,fc00:43f4:1eea:1::70,fc00:43f4:1eea:1::80,fc00:43f4:1eea:1::90,fc00:43f4:1eea:1::100,::1   
-profile=kubernetes   apiserver-csr.json | cfssljson -bare /etc/kubernetes/pki/apiserver

3.2.3生成apiserver聚合证书

cfssl gencert   -initca front-proxy-ca-csr.json | cfssljson -bare /etc/kubernetes/pki/front-proxy-ca 

# 有一个警告，可以忽略

cfssl gencert  
-ca=/etc/kubernetes/pki/front-proxy-ca.pem

5.高可用配置（在Master服务器上操作）

注意* 5.1.1 和5.1.2 二选一即可

选择使用那种高可用方案

在《3.2.生成k8s相关证书》

若使用 nginx方案，那么为 --server=https://127.0.0.1:8443
若使用 haproxy、keepalived 那么为 --server=https://192.168.0.36:8443

5.1 NGINX高可用方案 （推荐）

5.1.1自己手动编译（推荐）

在所有节点执行

# 安装编译环境
yum install gcc -y

# 下载解压nginx二进制文件
# wget http://nginx.org/download/nginx-1.22.1.tar.gz
tar xvf nginx-*.tar.gz
cd nginx-*

# 进行编译
./configure --with-stream --without-http --without-http_uwsgi_module --without-http_scgi_module --without-http_fastcgi_module
make && make install 

# 拷贝编译好的nginx
node='k8s-master02 k8s-master03 k8s-node01 k8s-node02'
for NODE in $node; do scp -r /usr/local/nginx/ $NODE:/usr/local/nginx/; done

5.1.2使用我编译好的

# 使用我编译好的

cd kubernetes-v1.26.0/cby
# 拷贝我编译好的nginx
node='k8s-master01 k8s-master02 k8s-master03 k8s-node01 k8s-node02'
for NODE in $node; do scp nginx.tar $NODE:/usr/local/; done

# 其他节点上执行
cd /usr/local/
tar xvf nginx.tar 

5.1.3写入启动配置

在所有主机上执行

# 写入nginx配置文件
cat > /usr/local/nginx/conf/kube-nginx.conf  /etc/systemd/system/kube-nginx.service 

5.2 keepalived和haproxy 高可用方案 （不推荐）

5.2.1安装keepalived和haproxy服务

systemctl disable --now firewalld

setenforce 0
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config

yum -y install keepalived haproxy

5.2.2修改haproxy配置文件（两台配置文件一样）

# cp /etc/haproxy/haproxy.cfg /etc/haproxy/haproxy.cfg.bak

cat >/etc/haproxy/haproxy.cfg

5.2.3Master01配置keepalived master节点

#cp /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf.bak

cat > /etc/keepalived/keepalived.conf 

5.2.4Master02配置keepalived backup节点

# cp /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf.bak

cat > /etc/keepalived/keepalived.conf 

5.2.5Master03配置keepalived backup节点

# cp /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf.bak

cat > /etc/keepalived/keepalived.conf 

5.2.6健康检查脚本配置（两台lb主机）

cat >  /etc/keepalived/check_apiserver.sh 

5.2.7启动服务

systemctl daemon-reload
systemctl enable --now haproxy
systemctl enable --now keepalived

5.2.8测试高可用

# 能ping同

[root@k8s-node02 ~]# ping 192.168.0.36

# 能telnet访问

[root@k8s-node02 ~]# telnet 192.168.0.36 8443

# 关闭主节点，看vip是否漂移到备节点

6.k8s组件配置（区别于第4点）

所有k8s节点创建以下目录

mkdir -p /etc/kubernetes/manifests/ /etc/systemd/system/kubelet.service.d /var/lib/kubelet /var/log/kubernetes

6.1.创建apiserver（所有master节点）

6.1.1master01节点配置

cat > /usr/lib/systemd/system/kube-apiserver.service 

6.1.2master02节点配置

cat > /usr/lib/systemd/system/kube-apiserver.service 

6.1.3master03节点配置

cat > /usr/lib/systemd/system/kube-apiserver.service  

6.1.4启动apiserver（所有master节点）

systemctl daemon-reload && systemctl enable --now kube-apiserver

# 注意查看状态是否启动正常
# systemctl status kube-apiserver

6.2.配置kube-controller-manager service

# 所有master节点配置，且配置相同
# 172.16.0.0/12为pod网段，按需求设置你自己的网段

cat > /usr/lib/systemd/system/kube-controller-manager.service 

6.2.1启动kube-controller-manager，并查看状态

systemctl daemon-reload
systemctl enable --now kube-controller-manager
# systemctl  status kube-controller-manager

6.3.配置kube-scheduler service

6.3.1所有master节点配置，且配置相同

cat > /usr/lib/systemd/system/kube-scheduler.service 

6.3.2启动并查看服务状态

systemctl daemon-reload
systemctl enable --now kube-scheduler
# systemctl status kube-scheduler

7.TLS Bootstrapping配置

7.1在master01上配置

# 在《5.高可用配置》选择使用那种高可用方案
# 若使用 haproxy、keepalived 那么为 `--server=https://192.168.0.36:8443`
# 若使用 nginx方案，那么为 `--server=https://127.0.0.1:8443`

--kubeconfig=/etc/kubernetes/bootstrap-kubelet.kubeconfig

kubectl config use-context tls-bootstrap-token-user@kubernetes     
--kubeconfig=/etc/kubernetes/bootstrap-kubelet.kubeconfig

# token的位置在bootstrap.secret.yaml，如果修改的话到这个文件修改
mkdir -p /root/.kube ; cp /etc/kubernetes/admin.kubeconfig /root/.kube/config

7.2查看集群状态，没问题的话继续后续操作

kubectl get cs

# 切记执行，别忘记！！！
kubectl create -f bootstrap.secret.yaml

8.node节点配置

8.1.在master01上将证书复制到node节点

cd /etc/kubernetes/
 
for NODE in k8s-master02 k8s-master03 k8s-node01 k8s-node02; do ssh $NODE mkdir -p /etc/kubernetes/pki; for FILE in pki/ca.pem pki/ca-key.pem pki/front-proxy-ca.pem bootstrap-kubelet.kubeconfig kube-proxy.kubeconfig; do scp /etc/kubernetes/$FILE $NODE:/etc/kubernetes/${FILE}; done; done

8.2.kubelet配置

注意 ： 8.2.1 和 8.2.2 需要和 上方 2.1 和 2.2 对应起来

8.2.1当使用docker作为Runtime

cat > /usr/lib/systemd/system/kubelet.service 

8.2.2当使用Containerd作为Runtime （推荐）

mkdir -p /var/lib/kubelet /var/log/kubernetes /etc/systemd/system/kubelet.service.d /etc/kubernetes/manifests/

# 所有k8s节点配置kubelet service
cat > /usr/lib/systemd/system/kubelet.service 

8.2.3所有k8s节点创建kubelet的配置文件

cat > /etc/kubernetes/kubelet-conf.yml 

8.2.4启动kubelet

systemctl daemon-reload
systemctl restart kubelet
systemctl enable --now kubelet

8.2.5查看集群

[root@k8s-master01 ~]# kubectl  get node
NAME           STATUS     ROLES    AGE   VERSION
k8s-master01   Ready       18s   v1.27.1
k8s-master02   Ready       16s   v1.27.1
k8s-master03   Ready       16s   v1.27.1
k8s-node01     Ready       14s   v1.27.1
k8s-node02     Ready       14s   v1.27.1
[root@k8s-master01 ~]#

8.2.6查看容器运行时

[root@k8s-master01 ~]# kubectl describe node | grep Runtime
  Container Runtime Version:  containerd://1.6.20
  Container Runtime Version:  containerd://1.6.20
  Container Runtime Version:  containerd://1.6.20
  Container Runtime Version:  containerd://1.6.20
  Container Runtime Version:  containerd://1.6.20
[root@k8s-master01 ~]# kubectl describe node | grep Runtime
  Container Runtime Version:  docker://23.0.3
  Container Runtime Version:  docker://23.0.3
  Container Runtime Version:  docker://23.0.3
  Container Runtime Version:  docker://23.0.3
  Container Runtime Version:  docker://23.0.3

8.3.kube-proxy配置

8.3.1将kubeconfig发送至其他节点

for NODE in k8s-master02 k8s-master03; do scp /etc/kubernetes/kube-proxy.kubeconfig $NODE:/etc/kubernetes/kube-proxy.kubeconfig; done

for NODE in k8s-node01 k8s-node02; do scp /etc/kubernetes/kube-proxy.kubeconfig $NODE:/etc/kubernetes/kube-proxy.kubeconfig;  done

8.3.2所有k8s节点添加kube-proxy的service文件

cat >  /usr/lib/systemd/system/kube-proxy.service 

8.3.3所有k8s节点添加kube-proxy的配置

cat > /etc/kubernetes/kube-proxy.yaml 

8.3.4启动kube-proxy

 systemctl daemon-reload
 systemctl restart kube-proxy
 systemctl enable --now kube-proxy

9.安装网络插件

注意 9.1 和 9.2 二选其一即可，建议在此处创建好快照后在进行操作，后续出问题可以回滚

centos7 要升级libseccomp 不然 无法安装网络插件

# https://github.com/opencontainers/runc/releases
# 升级runc
# wget https://ghproxy.com/https://github.com/opencontainers/runc/releases/download/v1.1.4/runc.amd64

install -m 755 runc.amd64 /usr/local/sbin/runc
cp -p /usr/local/sbin/runc  /usr/local/bin/runc
cp -p /usr/local/sbin/runc  /usr/bin/runc

#下载高于2.4以上的包
yum -y install http://rpmfind.net/linux/centos/8-stream/BaseOS/x86_64/os/Packages/libseccomp-2.5.1-1.el8.x86_64.rpm


#查看当前版本
[root@k8s-master-1 ~]# rpm -qa | grep libseccomp

10.安装CoreDNS

10.1以下步骤只在master01操作

10.1.1修改文件

# 下载tgz包
helm repo add coredns https://coredns.github.io/helm
helm pull coredns/coredns
tar xvf coredns-*.tgz
cd coredns/

# 修改IP地址
vim values.yaml
cat values.yaml | grep clusterIP:
clusterIP: "10.96.0.10"

# 示例
---
service:
# clusterIP: ""
# clusterIPs: []
# loadBalancerIP: ""
# externalIPs: []
# externalTrafficPolicy: ""
# ipFamilyPolicy: ""
  # The name of the Service
  # If not set, a name is generated using the fullname template
  clusterIP: "10.96.0.10"
  name: ""
  annotations: {}
---

# 修改为国内源 docker源可选
sed -i "s#coredns/#registry.cn-hangzhou.aliyuncs.com/chenby/#g" values.yaml
sed -i "s#registry.k8s.io/cpa/#registry.cn-hangzhou.aliyuncs.com/chenby/#g" values.yaml

# 默认参数安装
helm install  coredns ./coredns/ -n kube-system

11.安装Metrics Server

11.1以下步骤只在master01操作

11.1.1安装Metrics-server

在新版的Kubernetes中系统资源的采集均使用Metrics-server，可以通过Metrics采集节点和Pod的内存、磁盘、CPU和网络的使用率

# 单机版 
wget https://mirrors.chenby.cn/https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
# 高可用版本
wget https://mirrors.chenby.cn/https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/high-availability.yaml


# 修改配置
vim components.yaml
vim high-availability.yaml

---
# 1
defaultArgs:
  - --cert-dir=/tmp
  - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
  - --kubelet-use-node-status-port
  - --metric-resolution=15s
  - --kubelet-insecure-tls
  - --requestheader-client-ca-file=/etc/kubernetes/pki/front-proxy-ca.pem
  - --requestheader-username-headers=X-Remote-User
  - --requestheader-group-headers=X-Remote-Group
  - --requestheader-extra-headers-prefix=X-Remote-Extra-

# 2
        volumeMounts:
        - mountPath: /tmp
          name: tmp-dir
        - name: ca-ssl
          mountPath: /etc/kubernetes/pki

# 3
      volumes:
      - emptyDir: {}
        name: tmp-dir
      - name: ca-ssl
        hostPath:
          path: /etc/kubernetes/pki
---


# 修改为国内源 docker源可选
sed -i "s#registry.k8s.io/metrics-server/#registry.cn-hangzhou.aliyuncs.com/chenby/#g" *.yaml

# 二选一
kubectl apply -f high-availability.yaml
# kubectl apply -f components.yaml

11.1.2稍等片刻查看状态

kubectl  top node
NAME           CPU(cores)   CPU%   MEMORY(bytes)   MEMORY%   
k8s-master01   154m         1%     1715Mi          21%       
k8s-master02   151m         1%     1274Mi          16%       
k8s-master03   523m         6%     1345Mi          17%       
k8s-node01     84m          1%     671Mi           8%

k8s-node03     96m          1%     769Mi           9%        
k8s-node04     68m          0%     673Mi           8%        
k8s-node05     82m          1%     679Mi           8% 

12.集群验证

12.1部署pod资源

cat

12.2用pod解析默认命名空间中的kubernetes

kubectl get svc
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1            443/TCP   17h

kubectl exec  busybox -n default -- nslookup kubernetes
3Server:    10.96.0.10
Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local

Name:      kubernetes
Address 1: 10.96.0.1 kubernetes.default.svc.cluster.local

12.3测试跨命名空间是否可以解析

kubectl exec  busybox -n default -- nslookup kube-dns.kube-system
Server:    10.96.0.10
Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local

Name:      kube-dns.kube-system
Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local

12.4每个节点都必须要能访问Kubernetes的kubernetes svc 443和kube-dns的service 53

telnet 10.96.0.1 443
Trying 10.96.0.1...
Connected to 10.96.0.1.
Escape character is '^]'.

 telnet 10.96.0.10 53
Trying 10.96.0.10...
Connected to 10.96.0.10.
Escape character is '^]'.

curl 10.96.0.10:53
curl: (52) Empty reply from server

12.5Pod和Pod之前要能通

# 可以连通证明这个pod是可以跨命名空间和跨主机通信的

12.6创建三个副本，可以看到3个副本分布在不同的节点上（用完可以删了）

cat > deployments.yaml 

13.安装dashboard

helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/
helm install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --namespace kube-system

13.1更改dashboard的svc为NodePort，如果已是请忽略

kubectl edit svc kubernetes-dashboard -n kube-system

  type: NodePort

13.2查看端口号

kubectl get svc kubernetes-dashboard -n kube-system
NAME                   TYPE       CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
kubernetes-dashboard   NodePort   10.108.120.110           443:30034/TCP   34s

13.3创建token

cat > dashboard-user.yaml 

13.3登录dashboard

https://192.168.0.31:30034/

14.ingress安装

14.1执行部署

wget https://mirrors.chenby.cn/https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/cloud/deploy.yaml


vim deploy.yaml 

cat deploy.yaml | grep image:
        image: registry.cn-hangzhou.aliyuncs.com/chenby/controller:v1.7.0 
        image: registry.cn-hangzhou.aliyuncs.com/chenby/kube-webhook-certgen:v1.3.0 
        image: registry.cn-hangzhou.aliyuncs.com/chenby/kube-webhook-certgen:v1.3.0 


cat > backend.yaml  backend.yaml 

14.2过滤查看ingress端口

[root@hello ~/yaml]# kubectl  get svc -A | grep ingress
ingress-nginx          ingress-nginx-controller             NodePort    10.104.231.36            80:32636/TCP,443:30579/TCP   104s
ingress-nginx          ingress-nginx-controller-admission   ClusterIP   10.101.85.88             443/TCP                      105s
[root@hello ~/yaml]#

15.IPv6测试

16.安装命令行自动补全功能

yum install bash-completion -y
source /usr/share/bash-completion/bash_completion
source > ~/.bashrc

附录
