Login to the system and set ip for second adapter

vi /etc/netplan/00-installer-config.yaml

network:
  ethernets:
    enp0s1:
      dhcp4: no
      gateway4: 192.168.64.1
      nameservers:
        addresses:
          - 192.168.32.1
      addresses:
        - 192.168.64.16/24
  version: 2

sudo netplan apply

Network configuration

Now your VM has two adapters:

One is NAT which will get an IP automatically, generally it's 10.0.2.15, this interface is for external access from your VM
One is host adapter which need create extra ip, which is configured as 192.168.34.2 the reason we need the host adapter and static IP is then we can set this static IP as k8s advertise IP and you can move your VM in different everywhere.(otherwise your VM IP would be changed in different environment)

Set no password for sudo

sudo vim /etc/sudoers

%sudo ALL=(ALL:ALL) NOPASSWD:ALL

Swap off

remove the line with swap keyword

sudo swapoff -a
sudo vi /etc/fstab

Letting iptables see bridged traffic

$ cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
overlay
br_netfilter
EOF

$ sudo modprobe overlay
$ sudo modprobe br_netfilter

$ cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-iptables  = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.ipv4.ip_forward                 = 1
EOF


$ sudo sysctl --system

$ lsmod | grep br_netfilter
$ lsmod | grep overlay

Add the Kubernetes apt repository

$ cat <<EOF | sudo tee /etc/apt/sources.list.d/kubernetes.list
 deb https://mirrors.aliyun.com/kubernetes/apt kubernetes-xenial main
EOF

Add Docker’s official GPG key:

$ curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -

Update the apt package index and install packages to allow apt to use a repository over HTTPS:

$ sudo apt-get update

$ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

开启ipvs(可以跳过)

在kubernetes中service有两种代理模型，一种是基于iptables（链表），另一种是基于ipvs（hash表）。ipvs的性能要高于iptables的，但是如果要使用它，需要手动载入ipvs模块。

# 安装ipset和ipvsadm：
sudo apt install -y ipset ipvsadm

# 配置加载模块
cat << EOF | sudo tee /etc/modules-load.d/ipvs.conf 
modprobe -- ip_vs
modprobe -- ip_vs_rr
modprobe -- ip_vs_wrr
modprobe -- ip_vs_sh
modprobe -- nf_conntrack
EOF


# 临时加载
modprobe -- ip_vs
modprobe -- ip_vs_rr
modprobe -- ip_vs_wrr
modprobe -- ip_vs_sh

# 开机加载配置，将ipvs相关模块加入配置文件中
cat <<EOF | sudo tee /etc/modules 
ip_vs_sh
ip_vs_wrr
ip_vs_rr
ip_vs
nf_conntrack
EOF

Installing containerd runtime

sudo apt install -y containerd
sudo mkdir -p /etc/containerd
containerd config default | sudo tee /etc/containerd/config.toml
sudo systemctl restart containerd

Update cgroupdriver to systemd

在 /etc/containerd/config.toml 中设置

sudo systemctl daemon-reload && systemctl restart containerd
sudo systemctl status containerd

# sandbox_image镜像源设置为阿里云google_containers镜像源
sudo sed -i "s#registry.k8s.io/pause:3.6#registry.aliyuncs.com/google_containers/pause:3.9#g"  /etc/containerd/config.toml

# 修改Systemdcgroup
sudo sed -i 's#SystemdCgroup = false#SystemdCgroup = true#g' /etc/containerd/config.toml

sudo systemctl restart containerd

Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:

$ sudo apt-get update
$ sudo apt-get install -y kubelet=1.27.1-00 kubeadm=1.27.1-00 kubectl=1.27.1-00
$ sudo apt-mark hold kubelet kubeadm kubectl

设置crictl

runtime-endpoint: unix:///var/run/containerd/containerd.sock
image-endpoint: unix:///var/run/containerd/containerd.sock
timeout: 10

kubeadm init

$ sudo kubeadm init \

Copy kubeconfig

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join 192.168.64.16:6443 --token oc9xch.aqw7m3oqny1hmyvr \
        --discovery-token-ca-cert-hash sha256:7abc5ab8e66376204beaf43432d17bb5871bd0893b980755f805ce8dd5e0cee2

$ kubectl taint nodes --all node-role.kubernetes.io/control-plane-
