騰訊雲安裝kubernetes(ubuntu20.4)

1、安裝docker

sudo apt install docker.io

2、修改 cgroupdriver to systemd

sudo vi /etc/docker/daemon.json

添加以下內容：
{
  "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 <<EOF | sudo tee /etc/modules-load.d/k8s.conf
br_netfilter
EOF

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

sudo sysctl --system

注意看有沒報錯
