本文主要是介绍死磕k8s之calico-环境准备，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
序言：
本篇文章主要是列出了calico系列文章解析的环境以及准备工作。
环境
- k8s: v1.19.3
- iptables: v1.4.21
- route: 2.10-alpha
- calico: v3.16.4
- tcpdump
calico使用的是ipip模式,calico默认是ipip模式
k8s没有高可用安装，1个master节点，2个work节点
k8s没有使用ipvs
工具安装
calicoctl安装
calicoctl是calico社区提供一个全局查看calico网络的工具，类似kubectl之k8s
- 下载二进制包
curl -O -L https://github.com/projectcalico/calicoctl/releases/download/v3.4.0/calicoctl
- 拷贝到正确的可执行路径
cp calicoctl /usr/bin/
- 授予可执行权限
chmod +x /usr/bin/calicoctl
4.尝试获取calico节点试试
DATASTORE_TYPE=kubernetes KUBECONFIG=~/.kube/config calicoctl get nodes
下载calico.yaml文件
curl https://docs.projectcalico.org/archive/v3.16/manifests/calico.yaml -O
示例
1.创建deployment
kubectl create deployment nginx --image=nginx --port=80
2.为了方便测试，可以把pod固定运行在某个节点
kubectl edit deployment nginx
# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
#
apiVersion: apps/v1

kubectl create svc nodeport nginx --tcp=8080:80
3.尝试用节点+ip访问nodeport试试
我的完整节点、路由和防火墙信息
节点信息
路由信息
master节点1
work节点1
work节点2
防火墙信息
master节点1防火墙
