k3s 基础 —— 配置 traefik dashboard

访问 traefik dashboard

端口转发

# 访问地址 http://192.168.0.201:9000/dashboard/#/
kubectl -n kube-system port-forward $(kubectl -n kube-system get pods --selector "app.kubernetes.io/name=traefik" --output=name) 9000:9000 --address 0.0.0.0

配置域名

1、创建 ingress 配置文件 traefik-dashboard-web.yaml

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: traefik-dashboard-web
  namespace: kube-system
spec:
  entryPoints:
    - web
  routes:
    - kind: Rule
      match: Host(`traefik.domain.com`) && (PathPrefix(`/dashboard`) || PathPrefix(`/api`))
      services:
        - kind: TraefikService
          name: api@internal # 固定值，不用修改

2、执行部署

kubectl apply -f traefik-dashboard-web.yaml

3、配置 DNS 解析，访问地址 https://traefik.domain.com/dashboard/#/

开启跨命名空间访问

默认情况 traefik ingress 是不开启此项功能的，需要手动启用

新增配置文件 /var/lib/rancher/k3s/server/manifests/traefik-config.yaml

apiVersion: helm.cattle.io/v1
kind: HelmChartConfig
metadata:
  name: traefik
  namespace: kube-system
spec:
  valuesContent: |-
    globalArguments:
    - "--providers.kubernetescrd.allowCrossNamespace=true"

部署

kubectl apply -f traefik-config.yaml
