二跳仿、Kubernetes 鏡像簡介
Kubernetes 是一個開源系統(tǒng)蹲嚣，用于容器化應(yīng)用的自動部署伍纫、擴縮和管理松却。它將構(gòu)成應(yīng)用的容器按邏輯單位進行分組以便于管理和發(fā)現(xiàn)池充。

三、Kubernetes 鏡像配置方法
基于CentOS / RHEL / Fedora系統(tǒng)配置方法
（1）查看系統(tǒng)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 <<EOF > /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：由于官網(wǎng)未開放同步方式, 可能會有索引gpg檢查失敗的情況, 這時請用
yum install -y --nogpgcheck kubelet kubeadm kubectl安裝
（3）關(guān)閉或允許SELINUX安全模式
① 執(zhí)行setenforce 0命令往扔，暫時允許SELINUX安全模式放行通過。重啟失效熊户。
[root@centos ~]# setenforce 0
[root@centos ~]# getenforce
permissive
② 編輯/etc/selinux/config配置文件萍膛，保存退出，重啟生效嚷堡。
[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）安裝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）啟動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.
