部署calico网络插件

部署calico网络插件

之前的k8s环境中主要使用了flannel作为网络插件，这次改用calico。calico支持多种安装方式，以下是具体的操作步骤。

1. 准备工作

1. 环境信息

# 系统信息
root@master1:~# cat /etc/issue
Ubuntu 24.04 LTS \n \l

root@master1:~# uname -r
6.8.0-31-generic

# k8s版本
root@master1:~# kubectl get node
NAME      STATUS     ROLES           AGE    VERSION
master1   NotReady   control-plane   2m2s   v1.28.2
node1     NotReady   <none>          84s    v1.28.2
node2     NotReady   <none>          79s    v1.28.2

2. 版本配套

以最新的calico v3.28版本为例，适配如下k8s版本，我选用这个版本进行安装。

• v1.27
• v1.28
• v1.29
• v1.30

参考自：System requirements | Calico Documentation (tigera.io)

2. Operator方式安装

1. 安装operator

# 下载operator资源清单文件
root@master1:~/calico# wget https://raw.githubusercontent.com/projectcalico/calico/v3.28.0/manifests/tigera-operator.yaml
# 或者
root@master1:~/calico# curl https://raw.githubusercontent.com/projectcalico/calico/v3.28.0/manifests/tigera-operator.yaml -O

# 创建应用资源清单文件，创建operator
root@master1:~/calico# kubectl create -f tigera-operator.yaml
