主机名解析

关闭swap
swapoff -a
sed -i '/\sswap\s/s/^/#/' /etc/fstab
安装ipvs
apt install ipset ipvsadm
cat > /etc/modules-load.d/ipvs.conf << EOF

安装containerd
https://github.com/containerd/containerd/releases/tag/v1.7.3
安装containerd
wget https://github.com/containerd/containerd/releases/download/v1.7.3/cri-containerd-1.7.3-linux-arm64.tar.gz
tar xf cri-containerd-1.7.3-linux-arm64.tar.gz -C /
生成配置
mkdir /etc/containerd
containerd config default > /etc/containerd/config.toml
修改配置
# vim /etc/containerd/config.toml
SystemdCgroup = true #配置systemdcgroup驱动程序
sandbox_image = "registry.aliyuncs.com/google_containers/pause:3.9" #因为k8s需要pause:3.9镜像，共用
开启containerd服务
ctr image pull registry.aliyuncs.com/google_containers/pause:3.9
systemctl enable --now containerd
containerd --version
安装runc
（可忽略，因为containerd自带）
https://github.com/opencontainers/runc/releases/tag/v1.1.5
安装k8s
安装kubelet kubeadm kubectl
https://developer.aliyun.com/mirror/kubernetes?spm=a2c6h.13651102.0.0.73281b11ZWDJ2s
apt-get update && apt-get install -y apt-transport-https
curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -
cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
EOF
apt-get update
apt-get install -y kubelet kubeadm kubectl
获取kubernetes 1.28组件容器镜像
root@k8s-master01:/etc# kubeadm config images list --image-repository=registry.aliyuncs.com/google_containers
ctr image pull registry.aliyuncs.com/google_containers/kube-apiserver:v1.28.3
ctr image pull registry.aliyuncs.com/google_containers/kube-controller-manager:v1.28.3
ctr image pull registry.aliyuncs.com/google_containers/kube-scheduler:v1.28.3

ctr image pull registry.aliyuncs.com/google_containers/pause:3.9
ctr image pull registry.aliyuncs.com/google_containers/etcd:3.5.9-0
ctr image pull registry.aliyuncs.com/google_containers/coredns:v1.10.1
拉取镜像
kubeadm config images pull --image-repository=registry.aliyuncs.com/google_containers
初始化集群
方法一（不太会 ipvs模式）
#打印初始化配置
kubeadm config print init-defaults --component-configs KubeletConfiguration
advertiseAddress: 192.168.195.20
criSocket: unix:///var/run/containerd/containerd.sock
imageRepository: registry.aliyuncs.com/google_containers
kubernetesVersion: 1.28.3
serviceSubnet: 192.168.10.0/24
方法二（iptables模式）
kubeadm init \
--apiserver-advertise-address=192.168.195.20 \
--kubernetes-version=v1.28.3 \
--pod-network-cidr=192.168.20.0/24 \
--service-cidr=192.168.10.0/24 \
--token-ttl=0 \
--cri-socket unix:///var/run/containerd/containerd.sock \
--upload-certs \
--image-repository=registry.aliyuncs.com/google_containers
