kubernetes1.24从构建到躺平「一」

三台设备:

1台master节点

2台slave节点

OS:

一:前期环境准备

1)所有节点安装apt-transport-https

root@srv1:~echo"br_netfilter"/etc//@srv1:~sysctl--system

3)取消并注释fstab中的swap

root@srv1:~/dev/disk/by-uuid/aa1f65c9-2728-4763-9f2b-d6d0bc1ee92enoneswapsw00swapoff-a

4)在所有节点上安装Kubeadm,Kubelet,Kubectl

root@srv1:~chmod644/etc/apt//@srv1:~aptupdate;aptinstallkubeadmkubeletkubectl-y

5)所有节点安装

root@srv1:~echo"deb$(lsb_release-cs)stable"/etc/apt//@srv1:~containerdconfigdefault/etc/containerd/@srv1:~sed-i'spoint=""sed-i'ssandbox_image="/google_containers/

二:配置Master节点

1)初始化k8s并指定APIServer及pod所用的网络ID

root@srv1:~echo"exportKUBECONFIG=/etc/kubernetes/".bashrcroot@srv1:~/google_containers//google_containers//google_containers//google_containers//google_containers//google_containers//google_containers/

3)配置PodFlannelNetwork

5)确认Master节点所有的namespaces
