二、Kubernetes 镜像简介

Kubernetes 是一个开源系统，用于容器化应用的自动部署、扩缩和管理。它将构成应用的容器按逻辑单位进行分组以便于管理和发现。

三、Kubernetes 镜像配置方法

基于CentOS / RHEL / Fedora系统配置方法

（1）查看系统版本信息

 [root@centos ~]# hostnamectl
  Static hostname: centos
  Icon name: computer-vm
  Chassis: vm
  Machine ID: f6fc8fb7991c4c518238af7c75f16046
  Boot ID: baa5dae1c7614a0790ac9c3b5c0a9b7b
  Virtualization: vmware
  Operating System: CentOS Linux 7 (Core)
  CPE OS Name: cpe:/o:centos:centos:7
  Kernel: Linux 3.10.0-1160.el7.x86_64
  Architecture: x86-64

（2）添加并查看 Kubernetes.repo YUM源

 [root@centos ~]# cat < /etc/yum.repos.d/kubernetes.repo
 > [kubernetes]
 > name=Kubernetes
 > baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
 > enabled=1
 > gpgcheck=1
 > repo_gpgcheck=1
 > gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
 > EOF
 [root@centos ~]# cat /etc/yum.repos.d/kubernetes.repo
 [kubernetes]
 name=Kubernetes
 baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
 enabled=1
 gpgcheck=1
 repo_gpgcheck=1
 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
 [root@centos ~]#

PS：由于官网未开放同步方式, 可能会有索引gpg检查失败的情况, 这时请用 yum install -y --nogpgcheck kubelet kubeadm kubectl 安装

（3）关闭或允许SELINUX安全模式

① 执行setenforce 0命令，暂时允许SELINUX安全模式放行通过。重启失效。

[root@centos ~]# setenforce 0
 [root@centos ~]# getenforce
 permissive

② 编辑/etc/selinux/config配置文件，保存退出，重启生效。

[root@centos ~]# vim /etc/selinux/config
 [root@centos ~]# cat /etc/selinux/config
 
 # This file controls the state of SELinux on the system.
 # SELINUX= can take one of these three values:
 #     enforcing - SELinux security policy is enforced.
 #     permissive - SELinux prints warnings instead of enforcing.
 #     disabled - No SELinux policy is loaded.
 SELINUX=disabled
 # SELINUXTYPE= can take one of three values:
 #     targeted - Targeted processes are protected,
 #     minimum - Modification of targeted policy. Only selected processes are protected.
 #     mls - Multi Level Security protection.
 SELINUXTYPE=targeted
 
 
 [root@centos ~]# getenforce
 Disabled

（4）安装kubernetes

[root@centos ~]# yum install -y kubelet kubeadm kubectl
 Loaded plugins: fastestmirror
 Loading mirror speeds from cached hostfile
  * base: mirrors.aliyun.com
  * extras: mirrors.aliyun.com
  * updates: mirrors.aliyun.com
 Package kubelet-1.22.4-0.x86_64 already installed and latest version
 Package kubeadm-1.22.4-0.x86_64 already installed and latest version
 Package kubectl-1.22.4-0.x86_64 already installed and latest version
 Nothing to do
 [root@centos ~]#

（5）启动kubernetes

[root@centos ~]# systemctl start kubelet
 [root@centos ~]# systemctl enable kubelet
 Created symlink from /etc/systemd/system/multi-user.target.wants/kubelet.service to /usr/lib/systemd/system/kubelet.service.
