The ingress API objects are interpreted by ingress controllers. Depending on your Kubernetes installation you have to make sure that this ingress controller is up and running.
When using minikube to follow these examples you can activate an ingress controller using the following command:
minikube addons enable ingress
Ingresses will be made available under the ip address of the virtual machine minikube has created. This ip address can be found using:
minikube ip
The example below requires a hostname in your ingress definition it is recommended to e.g. put this Ip address and a name into your /etc/hosts by adding a line like this:
192.168.99.100 minikube
(where 192.168.99.100 would be the result of minikube ip)
The setup of this example includes multiple config files:
- nginx_ingress.yaml contains a deployment and service for an nginx webserver
- httpd_ingress.yaml contains a deployment and service for an apache based server
- ingresses.yaml contains the ingress definitions for both servers
To apply all those configurations use:
kubectl apply -f nginx_ingress.yaml
kubectl apply -f httpd_ingress.yaml
kubectl apply -f ingresses.yaml
Open your browser and point to http://minikube/nginx to see the answer of the nginx service and to http://minikube/httpd to see the answer of the Apache service.
