腾讯云安装kubernetes(ubuntu20.4)

1、安装docker

sudo apt install docker.io

2、修改 cgroupdriver to systemd

sudo vi /etc/docker/daemon.json

添加以下内容：
{
  "exec-opts": ["native.cgroupdriver=systemd"]
}

sudo systemctl daemon-reload
sudo systemctl restart docker

3、更新apt-get

sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl

4、iptables see bridged traffic

cat < 
sudo sysctl --system
 
注意看有没报错
 
 
5、install kubeadm
 
sudo curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -
 
6、 添加Kubernetes apt repository
 
sudo tee /etc/apt/sources.list.d/kubernetes.list <<-'EOF'
deb https://mirrors.aliyun.com/kubernetes/apt kubernetes-xenial main
EOF
 
7、安装kubelet, kubeadm and kubectl
 
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
sudo apt-mark hold kubelet kubeadm kubectl
 
8、初始化
 
kubeadm init   --image-repository registry.aliyuncs.com/google_containers   --kubernetes-version v1.22.2   --pod-network-cidr=192.168.0.0/16   --apiserver-advertise-address=10.0.20.5
 
apiserver-advertise-address是宿主机ip
 
 
9、复制kubeconfig
 
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
 
kubectl taint nodes --all node-role.kubernetes.io/master-
 
10、安装calico cni plugin
 
sudo kubectl create -f https://docs.projectcalico.org/manifests/tigera-operator.yaml
sudo kubectl create -f https://docs.projectcalico.org/manifests/custom-resources.yaml
