1 Shell工具
xshell 免费版,工具菜单下可选,同时控制所有的会话,后面不同节点安装Kubernetes会提高效率
2 节点规划
Linux为Ubuntu Server 22.04,下载地址 https://ubuntu.com/download/server
域名 | IP | 资源 | 节点名 |
k8s-master | 192.168.0.150 | 8C16G | k8s-master |
k8s-node1 | 192.168.0.151 | 4C8G | k8s-node1 |
k8s-node1 | 192.168.0.152 | 4C8G | k8s-node2 |
3 虚拟机
3.1 版本
VMware Workstation 15 Pro,本人安装时间较早。VM已免费,可自行下载高版本
3.2 安装ubuntu22.04
1. 下载成功后开始安装虚拟机,安装后的虚拟机可当作“模板虚拟机”(虚拟机网络选择桥接模式)
2. 保留“模板虚拟机”,深度克隆出安装Kubernetes的其他虚拟机(根据预计Kubernetes的规模确定虚拟机个数,本文个数为3)
3. 点击Clone(克隆)后,注意下图选择,最终由Ubuntu22.04深度克隆出Ubuntu22.04-master、Ubuntu22.04-node1、Ubuntu22.04-node2。后文 Ubuntu22.04-master、Ubuntu22.04-node1、Ubuntu22.04-node2 分别简称master、node1、node2
4. 新增 /etc/hosts 配置, master、node1、node2 的 hostname 为k8s-master、k8s-node1、k8s-node2
3.3 Shell连接master
1. master 初次安装后,网络默认为自动获取IP地址,但目前并不知道IP是多少,shell工具也无法登录
2. 使用 ifconfig 命令查看IP(工具依赖需安装:apt install net-tools)
3. VM终端复制、粘贴功能不友好,通过IP可shell登录,提升对master、node1、node2的配置效率,先用安装虚拟机时设置的普通用户登录master,登录后 sudo passwd root 设置 root 密码,登录前需通过VM终端配置root登录的权限 参考
4. 配置master静态IP,vim /etc/netplan/00-installer-config.yaml 参考
修改前
# This is the network config written by 'subiquity'
network:
ethernets:
ens33:
dhcp4: true
version: 2
修改后
# This is the network config written by 'subiquity'
network:
ethernets:
ens33:
addresses:
- 192.168.0.150/24
routes:
- to: default

nameservers:
addresses:
- 114.114.114.114
search:

version: 2
注意:规划IP时,IP地址分配千万注意不要与主机IP以及其他IP冲突
3.4 Shell连接node1、node2
参考shell连接master即可
3.5 禁用swap
4. 安装Kubernetes
4.1 安装 containerd 1.7.23
1. 多节点同时下载contaienrd,同时检查其他节点是否下载成功
下载containerd命令:
wget https://github.com/containerd/containerd/releases/download/v1.7.23/containerd-1.7.23-linux-amd64.tar.gz
2. 解压缩:tar Cxzvf /usr/local containerd-2.0.0-linux-amd64.tar.gz;同时检查其他节点
root@k8s-master:~# ll /usr/local/bin
total 134200
drwxr-xr-x 2 root root 4096 Oct 14 20:42 ./
drwxr-xr-x 10 root root 4096 Feb 17 2023 ../

-rwxr-xr-x 1 root root 28849992 Oct 14 20:42 ctr*
3. 配置 containerd 配置文件,执行 containerd config default 获取默认配置内容,配置到 /etc/containerd/config.toml
root@k8s-master:~# containerd config default
disabled_plugins = []
imports = []
oom_score= 0
plugin_dir = ""
required_plugins = []
root = "/var/lib/containerd"
state = "/run/containerd"
temp = ""
version = 2
[cgroup]
path = ""
......
4. 配置 systemd
cgroup 驱动 参考
root@k8s-master:~# cat /etc/containerd/config.toml | grep SystemdCgroup
SystemdCgroup = true
5. 配置containerd systemd service,参考 启动服务成功
root@k8s-master:~# systemctl start containerd
root@k8s-master:~# systemctl status containerd
● containerd.service - containerd container runtime

4.2 安装 runc 1.2.2
1. 参考
下载runc1.2.2:
wget https://github.com/opencontainers/runc/releases/download/v1.2.2/runc.amd64
2. 按照参考中进行解压即可
4.3 安装 CNI 插件 1.6.0
1. 参考
下载cni插件命令:
wget https://github.com/containernetworking/plugins/releases/download/v1.6.0/cni-plugins-linux-amd64-v1.6.0.tgz
4.4 安装 kubeadm
1. 准备开始
2. 确保每个节点上 MAC 地址和 product_uuid 唯一:cat /sys/class/dmi/id/product_uuid
3. 检查网络适配器:执行命令 echo 1 > /proc/sys/net/ipv4/ip_forward
4. 检查端口:nc 127.0.0.1 6443 -v
5. 安装容器运行时,上面已经安装contaienrd
6. 安装 kubeadm、kubelet 和 kubectl 参考
- 更新
apt
包索引并安装使用 Kubernetesapt
仓库所需要的包
sudo apt-get update
# apt-transport-https 可能是一个虚拟包(dummy package);如果是的话,你可以跳过安装这个包sudo apt-get install -y apt-transport-https ca-certificates curl gpg
-
下载用于 Kubernetes 软件包仓库的公共签名密钥。所有仓库都使用相同的签名密钥,因此你可以忽略URL中的版本
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.30/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
-
添加 Kubernetes
apt
仓库
echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.30/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
-
添加 Kubernetes
apt
仓库
echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.30/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
-
更新
apt
包索引,安装 kubelet、kubeadm 和 kubectl,并锁定其版本
sudo apt-get update sudo apt-get install -y kubelet kubeadm kubectl sudo apt-mark hold kubelet kubeadm kubectl
7. 此时 kubelet 处于不断重启状态,等待 kubeadm 的指令
8. 运行 crictl 命令,如 crictl ps 如下警告
-
运行时和镜像的默认 endpoints 配置已经,需要手动设置
-
解决方案2种,环境变量 或 配置crictl.yaml
环境变量:
export CONTAINER_RUNTIME_ENDPOINT=unix:///run/containerd/containerd.sock export IMAGE_SERVICE_ENDPOINT=unix:///run/containerd/containerd.sock
配置crictl.yaml
cat <<EOF> /etc/crictl.yaml runtime-endpoint: unix:///run/containerd/containerd.sock image-endpoint: unix:///run/containerd/containerd.sock timeout: 10 debug: false EOF
配置说明
runtime-endpoint = "unix:///run/containerd/containerd.sock" # 指定 containerd 的运行时端点,使用本地 Unix 套接字进行通信
image-endpoint = "unix:///run/containerd/containerd.sock" # 指定 containerd 的镜像端点,同样使用本地 Unix 套接字进行通信
timeout = 2 # 设置操作的超时时间(单位为秒)
debug = false # 是否开启调试模式
pull-image-on-create = false # 是否在创建时立即拉取镜像(未配置)
systemctl restart containerd
- 再次执行,警告解除
9. kubeadm排障参考
4.5 kubeadm 部署集群
1. 从这里开始要关闭 Xshell 发送到所有回话的开关,master与node1,node2操作不同,需要相同操作再次打开即可
通过 --image-repository=registry.aliyuncs.com/google_containers 使用阿里云镜像,部署命令如下
kubeadm init \
--image-repository=registry.aliyuncs.com/google_containers \
--pod-network-cidr=172.16.0.0/16 \
--apiserver-advertise-address=192.168.0.150 \

Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.0.150:6443 --token xkqp9q.ti1oioinh145vm3d \
--discovery-token-ca-cert-hash sha256:c3bd7dd4f6f49d9204ca460e1909b3e3f099a4ccf6ae0775067881aeb94e265b
3. 使用kubectl 命令前,按照部署后的提示配置kube config
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
4. 部署成功,查看节点

7. 查看节点
root@k8s-master:~# kubectl get node
NAME STATUS ROLES AGE VERSION
k8s-master NotReady control-plane 2m21s v1.30.8
k8s-node1 NotReady <none> 33s v1.30.8
k8s-node2 NotReady <none> 5s v1.30.8
4.6 安装 Calico
2. 每个节点都需要下载calico镜像,版本v3.29.1,仓库地址:https://docker.aityp.com
ctr -n k8s.io images pull swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/calico/cni:v3.29.1
ctr -n k8s.io images pull swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/calico/node:v3.29.1

ctr -n k8s.io images delete swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/calico/kube-controllers:v3.29.1
3. 下载calico编排文件
-
需要将下两行注释到来,value 配置为 kubeadm init 时 --pod-network-cidr 参数对应的值
-
kubectl apply -f calico.yaml 后查看 pod 运行情况
至此kubernetes v1.3.0部署完成!!!
