1.基础环境部署

sudo apt-get update     #更新源及/etc/apt/sources.list
sudo apt-get  -y upgrade   #更新已安装的软件包 

sudo apt -y install vim lrzsz wget 
sudo swapoff -a # 临时  
sudo sed -i 's/.*swap.*/#&/' /etc/fstab # 永久

sudo timedatectl set-timezone Asia/Shanghai  &&  sudo systemctl restart rsyslog 
sudo apt install ntpdate -y && sudo ntpdate time.windows.com
sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
sudo lsmod | grep br_netfilter

sudo cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1

sudo sysctl --system

sudo cat > /etc/sysctl.d/10-network-security.conf << EOF
net.ipv4.conf.default.rp_filter=1
net.ipv4.conf.all.rp_filter=1

2.1 安装docker

sudo apt update && sudo apt-get  -y upgrade
