kubernetes标准化镜像构建

一、网络配置

1.1、yum 安装 net-tools

cd /etc/sysconfig/network-script/ 
vi ifcfg-eth0

修改ONBOOT=yes，重启电脑

_{1.2、安装net-tools}

yum install net-tools

可以通过ifconfig查看网卡Ip配置

二、安全相关

2.1、关闭所有节点的SELinux

vi /etc/selinux/config

修改：SELINUX=disabled

2.2 关闭防火墙

systemctl stop firewalld
systemctl disable firewalld swapoff -a

2.3 永久性禁用swap

vi /etc/fstab

 在行首加 #，注释该行，重启电脑

三、安装Docker、官网

https://docs.docker.com/install/linux/docker-ce/centos/

yum install -y yum-utils \ device-mapper-persistent-data \ lvm2
 
yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo
 
yum install docker-ce docker-ce-cli containerd.io systemctl enable docker systemctl start docker
 
docker -v

配置阿里云加速

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://byedr9vm.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

四、配置安装K8S

4.1配置源

cat>>/etc/yum.repos.d/kubrenetes.repo<<EOF
[kubernetes]
name=Kubernetes Repo
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
EOF
