部署版本
首先要确定部署的版本
查询Kubernetes对Docker支持的情况
kubernetes/dependencies.yaml at master · kubernetes/kubernetes (github.com)
查询Kubernetes Dashboard对Kubernetes支持的情况
Releases · kubernetes/dashboard (github.com)
名称 | 版本 |
---|---|
kubernetes | 1.23 |
Docker | 20.10.22 |
Kubernetes Dashboard | 2.5.1 |
部署的步骤为
- 修改服务器hostname及ip
- 配置环境及防火墙
- 调整服务器系统设置
- 部署Docker
- 部署Master节点
- Node节点追加
- 安装k8s Dashboard
准备工作
- 节点CPU核数必须是 ≥2核且内存要求必须≥2G,否则k8s无法启动
- DNS网络: 最好设置为本地网络连通的DNS,否则网络不通,无法下载一些镜像
配置hostname及静态IP
节点hostname | 作用 | IP |
---|---|---|
kubemaster | master | 192.168.1.4 |
kubeworker1 | work1 | 192.168.1.5 |
kubeworker2 | work2 | 192.168.1.6 |
如表格所示,将192.168.1.4服务器的hostname
配置为kubemaster
,将192.168.1.5服务器的hostname
配置为kubeworker1
,将192.168.1.6服务器的hostname
配置为kubeworker2
。并将每个服务器的网卡配置为静态IP,不使用DHCP
Master节点
## 更改节点hostname
[root@localhost ~]# hostnamectl set-hostname kubemaster --static
## 获取节点网卡名
[root@localhost ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lovalid_lft forever preferred_lft foreverinet6 ::1/128 scope host valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000link/ether fa:16:3e:0b:68:40 brd ff:ff:ff:ff:ff:ffinet 192.168.1.4/24 brd 192.168.1.255 scope global noprefixroute dynamic eth0valid_lft 77613sec preferred_lft 77613secinet6 fe80::f816:3eff:fe0b:6840/64 scope link valid_lft forever preferred_lft forever
此时需要设置
eth0
网卡,命令格式为vi /etc/sysconfig/network-scripts/ifcfg-[网卡名称]
## 设置eth0网卡
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
修改以下内容
BOOTPROTO="static" # dhcp改为static
ONBOOT="yes" # 开机启用本配置
IPADDR=192.168.1.4 # 静态IP
GATEWAY=192.168.1.1 # 默认网关
NETMASK=255.255.255.0 # 子网掩码
DNS1=114.114.114.114 # DNS 配置
DNS2=8.8.8.8 # DNS 配置【必须配置,否则SDK镜像下载很慢】
随后重启服务器并编辑hosts文件
## 重启服务器
[root@localhost ~] reboot
## 查看hostname是否生效
[root@kubemaster ~]# hostname
kubemaster
## 编辑/etc/hosts文件,配置映射关系
[root@kubemaster ~]# vi /etc/hosts
添加hosts文件的规则
192.168.1.4 kubemaster
192.168.1.5 kubeworker1
192.168.1.6 kubeworker2
worker1节点
# 更改节点hostname
[root@localhost ~]# hostnamectl set-hostname kubeworker1 --static
# 获取节点网卡名
[root@localhost ~]# ip addr

192.168.1.5 kubeworker1
192.168.1.6 kubeworker2
环境及防火墙配置
注意:
此项需要每一台机器都安装
安装依赖环境
yum install -y conntrack ntpdate ntp ipvsadm ipset jq iptables curl sysstatlibseccomp wget vim net-tools git iproute lrzsz bash-completion tree bridge-utils unzip bind-utils gcc
用普通的noteport不行,必须用ingress
防火墙配置
关闭防火墙
注意:
生产环境建议放行端口
systemctl stop firewalld && systemctl disable firewalld
iptables配置
注意:
iptables -F
命令为清空iptables规则,生产环境下会清空已有规则,需谨慎执行
安装、启动iptables,设置开机自启,清空iptables规则,保存当前规则到默认规则
yum -y install iptables-services && systemctl start iptables && systemctl enable iptables && iptables -F && service iptables save
关闭selinux
注意:
关闭Selinux是为了放行脚本(安装的时候需要执行脚本)
# 关闭swap分区【虚拟内存】并且永久关闭虚拟内存
[root@kubemaster ~]# swapoff -a && sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
# 关闭selinux
[root@kubemaster ~]# swapoff -a && sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
[root@kubemaster ~]# setenforce 0 && sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config
setenforce: SELinux is disabled
系统设置调整
注意:
此项需要每一台机器都设置
调整内核参数
K8s必须禁用ipv6

modprobe ip_conntrack#手动刷新,让优化文件立即生效
sysctl -p /etc/sysctl.d/kubernetes.conf
调整系统时区
#设置系统时区为中国/上海
timedatectl set-timezone "Asia/Shanghai"
#将当前的UTC 时间写入硬件时钟
timedatectl set-local-rtc 0
#重启依赖于系统时间的服务
systemctl restart rsyslog
systemctl restart crond
关闭邮件服务(生产环境别执行)
systemctl stop postfix && systemctl disable postfix
设置日志保存
- 创建保存日志的目录
[root@kubemaster ~]# mkdir /var/log/journal
- 创建配置文件存放目录
[root@kubemaster ~]# mkdir /etc/systemd/journald.conf.d
- 创建配置文件
cat > /etc/systemd/journald.conf.d/99-prophet.conf <<EOF

Master节点部署
注意:
此项需要安装在Master节点
修改配置文件
# 初始化配置文件
kubeadm config print init-defaults > kubeadm-init.yaml
# 修改配置文件
vi kubeadm-init.yaml
# 查看kubeadm版本
kubeadm version
需要修改的项
- 将
advertiseAddress: 1.2.3.4
修改为本地使用的IP地址,示例上使用的是192.168.1.4
,就修改为advertiseAddress: 192.168.1.4
- 将
kubernetesVersion: 1.23.0
修改为当前使用的版本,示例上使用的是1.23.15
,就修改为kubernetesVersion: 1.23.15
- 将
imageRepository: k8s.gcr.io
修改为imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers
- 增加Pod子网络,在
networking
下添加podSubnet: 10.244.0.0/16
修改完毕后文件如下
apiVersion: kubeadm.k8s.io/v1beta2

拉取镜像
[root@kubemaster ~]# kubeadm config images pull --config kubeadm-init.yaml
安装
[root@kubemaster ~]# kubeadm init --config kubeadm-init.yaml
初始化后,会出现以下命令,后面追加Node的时候需要用
kubeadm join 192.168.1.4:6443 --token abcdef.0123456789abcdef \--discovery-token-ca-cert-hash sha256:602efef33cee46c1aa6a95ddd0972606e826ef122f810930e835b4f536cddc14
网络配置
当前Master节点的STATUS是NotReady,是因为没有配置网络
## 配置kubectl执行命令环境
mkdir -p $HOME/.kube
cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
chown $(id -u):$(id -g) $HOME/.kube/config## 执行kubectl命令查看机器节点
[root@kubemaster ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
node NotReady control-plane,master 14m v1.23.15
配置Calico网络
下载配置文件
wget https://docs.projectcalico.org/manifests/calico.yaml
修改配置文件
这里需要指定网卡(添加IP_AUTODETECTION_METHOD
)
## 编辑calico.yaml
vi calico.yaml
下面的示例截取了部分配置文件,eth.*
的意思就是以eth
为开头的网卡,根据服务器的不同,前缀也会不同
# Cluster type to identify the deployment type
- name: CLUSTER_TYPEvalue: "k8s,bgp"
# IP automatic detection
- name: IP_AUTODETECTION_METHODvalue: "interface=eth.*"
# Auto-detect the BGP IP address.
- name: IPvalue: "autodetect"
# Enable IPIP
- name: CALICO_IPV4POOL_IPIPvalue: "Always"
安装
kubectl apply -f calico.yaml
此时查看node信息, Master的状态已经是Ready
了.
[root@kubemaster ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
node Ready control-plane,master 14m v1.23.15
Node节点追加
注意:
此项需要执行在Node节点
在其他Node执行以下命令即可
kubeadm join 192.168.1.4:6443 --token abcdef.0123456789abcdef \--discovery-token-ca-cert-hash sha256:602efef33cee46c1aa6a95ddd0972606e826ef122f810930e835b4f536cddc14
验证状态
[root@kubemaster ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
kubemaster Ready control-plane,master 14m v1.23.15
kubeworker1 Ready <none> 5m37s v1.23.15
kubeworker2 Ready <none> 5m28s v1.23.15
[root@kubemaster ~]# kubectl get pod -n kube-system -o wide
## 如果看到下面的pod状态都是Running状态,说明K8S集群环境就构建完成
安装 Kubernetes Dashboard
安装Dashboard
下载配置文件
wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.1/aio/deploy/recommended.yaml
配置外网访问
在recommended.yaml文件中寻找kubernetes-dashboard
,添加访问方式为NodePort,端口为30443,示例为配置文件需要修改的部分,需要添加type: NodePort
和nodePort: 30443
kind: Service
apiVersion: v1
metadata:labels:k8s-app: kubernetes-dashboardname: kubernetes-dashboardnamespace: kubernetes-dashboard
spec:type: NodePortports:- port: 443targetPort: 8443nodePort: 30443selector:k8s-app: kubernetes-dashboard
安装
kubectl apply -f recommended.yaml
检查安装情况
查看dashboard是否进行了配置,443:30443/TCP
即证明已配置完成
[root@kubemaster ~]# kubectl get svc -A | grep kubernetes-dashboard
