下载 calico manifests

curl -LO https://raw.githubusercontent.com/projectcalico/calico/refs/tags/v3.26.1/manifests/calico.yaml

修改 calico manifests 网卡名称

interface_name=$(ip route get 223.5.5.5 | grep -oP '(?<=dev\s)\w+' | head -n 1)
echo $interface_name
sed -i '/k8s,bgp/a \            - name: IP_AUTODETECTION_METHOD\n              value: "interface=INTERFACE_NAME"' calico.yaml
sed -i "s#INTERFACE_NAME#$interface_name#g" calico.yaml

查看修改结果

cat calico.yaml | grep IP_AUTODETECTION_METHOD
cat calico.yaml | grep interface=

修改 calico manifests Docker 镜像

sed -i "s#docker.io/calico/cni:v#lcr.loongnix.cn/calico/cni:#" calico.yaml
sed -i "s#docker.io/calico/node:v#lcr.loongnix.cn/calico/node:#" calico.yaml
sed -i "s#docker.io/calico/kube-controllers:v#lcr.loongnix.cn/calico/kube-controllers:#" calico.yaml

使用 calico manifests

kubectl apply -f calico.yaml

等待 calico 创建完成

while true; do
  pod_status=$(kubectl get pods --all-namespaces -o jsonpath="{range .items[*]}{.status.phase}{'\n'}{end}" | sort | uniq);
  echo $pod_status
  if echo "$pod_status" | grep -q "Pending"; then
    echo '等待 pod 运行';
    sleep 5;
  else
    break;
  fi
done

calico 创建完成效果

查看 pod

kubectl get pod -A -o wide

[root@anolis ~]# kubectl get pod -A -o wide
