calico網絡，默認是ipip模式（在每臺node主機創建一個tunl0網口，這個隧道鏈接所有的node容器網絡，官網推薦不同的ip網段適合，比如aws的不同區域主機），
修改成BGP模式，它會以daemonset方式安裝在所有node主機，每臺主機啓動一個bird(BGP
client)，它會將calico網絡內的所有node分配的ip段告知集羣內的主機，並通過本機的網卡eth0或者ens33轉發數據；
下載calico 權限和配置文件
kubectl apply -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/rbac-kdd.yaml
wget https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml
修改calico.yaml
- 修改ipip模式關閉 和typha_service_nam
- name: CALICO_IPV4POOL_IPIP
value: "off"
- name: IP_AUTODETECTION_METHOD
value: "interface=ens.*"
2）修改replicas
replicas: 1
revisionHistoryLimit: 2
3）修改pod的網段CALICO_IPV4POOL_CIDR
- name: CALICO_IPV4POOL_CIDR
value: "10.244.0.0/16"
4）如果手動下載鏡像請查看calico.yaml 文件裏面標註的鏡像版本 否則可以直接執行會自動下載
5）部署calico
kubectl apply -f calico.yaml
