二进制安装 calicoctl工具

1.1 安装 calicoctl工具

calicoctl 允许从命令创建，读取，更新和删除 Calico 对象

二进制方式安装 calicoctl 工具。
版本号选择自己 calico 的版本。

# https://github.com/projectcalico/calicoctl/releases/
kubectl get deployment -n kube-system calico-kube-controllers -o yaml | grep image  #查看calico版本
curl -O -L  https://github.com/projectcalico/calicoctl/releases/download/v3.17.2/calicoctl
mv calicoctl-linux-amd64 /usr/local/bin/calicoctl
chmod +x /usr/local/bin/calicoctl
export CALICO_DATASTORE_TYPE=kubernetes
export CALICO_KUBECONFIG=~/.kube/config

如果不希望每次执行 calicoctl 之前都需要设置环境变量，可以将环境变量信息写到永久写入到 /etc/calico/calicoctl.cfg 文件:
mkdir -vp /etc/calico/

apiVersion: projectcalico.org/v3
kind: CalicoAPIConfig
metadata:
spec:
  datastoreType: "kubernetes"       
  kubeconfig: "/root/.kube/config"

1.2 使用 calicoctl 工具

1.1.1 查看所有的BGP节点，若携带右侧参数则能输出AS号，一个编号就是一个自治系统

calicoctl get nodes --output=wide 
NAME
name-02
name-03

1.1.2 查看所有的BGP节点状态

[root@calico ~]# calicoctl node status
calicoctl node status
Calico process is running.

# 查看 BGP Peer
calicoctl get bgppeer

# 查看IP池相关信息
calicoctl get ipPool -o yaml [-o wide]

# 收集节点诊断
calicoctl node diags
