Deployment an ingress controller

README.md

Deloyment a nginx ingress

Step

1. Create configmap to store nginx.conf, which modified the events config
2. Apply nginx-deployment.yaml to deploy nginx pods
3. Apply nginx-service.yaml to deploy nginx services
4. Execute kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.7.0/deploy/static/provider/cloud/deploy.yaml to deploy a nginx ingress controller, once deployed, you can access http://localhost through browser. Because there is no ingress, so any request will get a 404 Not Found
5. Apply nginx-ingress.yaml to deploy ingress rul
