traefik 2.5版本的安装配置
介于网上traefik 2.X版本安装配置文档杂乱，参考了官方文档和踩坑后记录如下
kubernetes的安装配置 https://bbotte.github.io/virtualization/kubernetes-cluster-1-22-install
traefik2.5版本和之前配置不一样，因此下面记录配置步骤
先设置crd 和 rbac，参考链接https://doc.traefik.io/traefik/user-guides/crd-acme/#ingressroute-definition，修改了最后的namespace
vim traefik-crd.yaml

the backend did with it. However, the historic default was to always
auto-detect and set the header if it was nil, and it is going to
be kept that way in order to support users currently relying on
it. This middleware exists to enable the correct behavior until
at least the default one can be changed in a future version.

最后dashboard访问web页面，参考 https://doc.traefik.io/traefik/operations/api/#configuration

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute

spec:
entryPoints:
- web
routes:
- match: Host(`traefik.bbotte.github.io`)
kind: Rule
services:
- name: traefik
port: 8080
也可以使用ingress配置dashboard
vim traefik-dashboard.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: traefik-dashboard-ingress
namespace: kube-system
annotations:
kubernetes.io/ingress.class: traefik
traefik.ingress.kubernetes.io/router.entrypoints: web
spec:
rules:
- host: traefik.bbotte.github.io
http:
paths:
- pathType: Prefix
path: /
backend:
service:
name: traefik
port:
number: 8080
浏览器访问node节点IP:30088
绑定hosts文件或者使用dns解析，域名映射到node节点，访问域名即可
curl –resolve traefik.bbotte.com:80:192.168.3.14 http://traefik.bbotte.com/
对于k8s中的服务，traefik已经可以代理了，如果不想把traefik直接暴露到公网，前面多加一层nginx，这么配置：
upstream traefik_com {
server 192.168.3.13; #这3个是node节点，因为traefik以domoset方式部署在node节点上
server 192.168.3.14;
server 192.168.3.15;
}
server {
listen 80;
server_name _;
access_log /var/log/nginx/host.access.log main;
location / {
proxy_pass http://traefik_com;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
这样子，dns所有域名都指向此nginx的ip，只要是80端口的请求都会通过nginx转到traefik（node节点的80端口），traefik再去找k8s service通信，对流量的限制或者ip黑名单都可以在nginx上配置
