Kubernetes 1.9集群使用traefik发布服务(2)

# cat traefik-service.yaml
apiVersion: v1
kind: Service
metadata:
  name: traefik-web-ui
  namespace: kube-system
spec:
  selector:
    k8s-app: traefik-ingress-lb
  ports:
  - port: 80
targetPort: 8081

4、通过yaml文件创建clusterrole、clusterrolebinding、deployment、serviceaccount、service

# ls
# kubectl create -f traefik-rbac.yaml
# kubectl create -f traefik-deployment.yaml
# kubectl create -f traefik-service.yaml

# kubectl get pod -n kube-system
# kubectl get svc -n kube-system
# kubectl get svc

可以看到集群中default namespace中存在一个frontend服务。kube-system namespace中存在nginx-test、traefik-web-ui、kubernetes-dashboard三个服务。我们后续将创建4个ingress

通过web-ui可以看到在两个节点上各运行了一个pod

三、通过yaml文件创建ingress

# cat ui.yaml
apiVersion: v1
kind: Service
metadata:
  name: traefik-web-ui
  namespace: kube-system
spec:
  selector:
    k8s-app: traefik-ingress-lb
  ports:
  - port: 80
    targetPort: 8081
