二、Kubernetes 鏡像簡介

Kubernetes 是一個開源系統，用于容器化應用的自動部署、擴縮和管理。它将構成應用的容器按邏輯機關進行分組以便于管理和發現。

三、Kubernetes 鏡像配置方法

基于CentOS / RHEL / Fedora系統配置方法

（1）檢視系統版本資訊

[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）添加并檢視 ​

​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）關閉或允許SE​​LINUX​​安全模式

① 執行​

​setenforce 0​

​​指令，暫時允許SELINUX安全模式放行通過。重新開機失效。

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

② 編輯​

​/etc/selinux/config​

​​配置檔案，儲存退出，重新開機生效。

[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.
