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 <<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=Kubernetesbaseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/enabled=1gpgcheck=1repo_gpgcheck=1gpgkey=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 ~]# getenforcepermissive

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 ~]# getenforceDisabled （4）安装kubernetes [root@centos ~]# yum install -y kubelet kubeadm kubectlLoaded plugins: fastestmirrorLoading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.comPackage kubelet-1.22.4-0.x86_64 already installed and latest versionPackage kubeadm-1.22.4-0.x86_64 already installed and latest versionPackage kubectl-1.22.4-0.x86_64 already installed and latest versionNothing to do[root@centos ~]#

（5）启动kubernetes [root@centos ~]# systemctl start kubelet[root@centos ~]# systemctl enable kubeletCreated symlink from /etc/systemd/system/multi-user.target.wants/kubelet.service to /usr/lib/systemd/system/kubelet.service.
