1.所有主机配置

关闭swap

systemctl disable --now  swap.target
systemctl mask swap.target
sed '/swap/s/^/#/g' -i /etc/fstab

 安装docker

 配置可以使用harbor仓库

mkdir  /etc/docker/certs.d/reg.timinglee.org/ -p#在harbor主机中分发证书到所有主机[root@harbor ~]# for i in 100 10 20> do> scp /data/certs/timinglee.org.crt root@172.25.254.$i:/etc/docker/certs.d/reg.timinglee.org/ca.crt> done​systemctl enable  dockersystemctl restart docker​​

所有主机配置docker加速器

cat >/etc/docker/daemon.json <<EOF
{
  "registry-mirrors":["https://reg.timinglee.org"]
}
EOF
systemctl restart docker

docker info
可以看到
Registry Mirrors:
  https://reg.timinglee.org/

所有主机彼此建立解析

 vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.25.254.100     master
172.25.254.10      node1
172.25.254.20      node2
172.25.254.200     reg.timinglee.org

所有主机配置kubernetes安装源

 vim /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name = kubernetes
baseurl = https://mirrors.aliyun.com/kubernetes-new/core/stable/v1.35/rpm/
gpgcheck = 0


#检测
dnf list kubelet

以上操作完成后重启主机检测swap分区

swapon  -s  没有任何输出表示ok
