暴露HTTP服务是咱们常使用的，首先配置ingressroute。
    ingress-route.yaml

    1. apiVersion: traefik.containo.us/v1alpha1
    2. kind: IngressRoute
    3. metadata:
    4.   name: foo 
    5. spec:
    6.   entryPoints:
    7.   - web
    8.   routes:
    9.   - match: Host(`foo.rookieops.top`)
    10.     kind: Rule
    11.     services:
    12.     - name: foo
    13.       port: 8080

    然后在traefik中添加entrypoint:

    1. kind: Deployment
    2. apiVersion: extensions/v1beta1
    3. metadata:
    4.   name: traefik
    5.   namespace: kube-system 
    6.   labels:
    7.     k8s-app: traefik-ingress-lb
    8. spec:
    9.   selector:
    10.     matchLabels:
    11.       k8s-app: traefik-ingress-lb
    12.   template:
    13.     metadata:
    14.       labels:
    15.         k8s-app: traefik-ingress-lb
    16.         name: traefik-ingress-lb
    17.     spec:
    18.       serviceAccountName: traefik-ingress-controller
    19.       tolerations:
    20.       - operator: "Exists"
    21.       nodeSelector:
    22.         kubernetes.io/hostname: 172.16.0.33
    23.       containers:
    24.       - image: traefik:v2.0
    25.         name: traefik-ingress-lb
    26.         ports:
    27.         - name: web
    28.           containerPort: 80
    29.         - name: websecure
    30.           containerPort: 443
    31.         - name: admin
    32.           containerPort: 8080
    33.         - name: redis
    34.           containerPort: 6379
    35.         args:
    36.         - --entrypoints.web.Address=:80
    37.         - --entrypoints.websecure.Address=:443
    38.         - --entrypoints.redis.Address=:6379
    39.         - --api.insecure=true
    40.         - --providers.kubernetescrd
    41.         - --api
    42.         - --api.dashboard=true
    43.         - --accesslog

    然后创建配置清单就可以了。
