Deploying the Nginx Ingress controller

This example aims to demonstrate the deployment of an nginx ingress controller and with the use of an annotation in the Ingress rule be able to customize the nginx configuration.

Default Backend

The default backend is a Service capable of handling all url paths and hosts the nginx controller doesn't understand. This most basic implementation just returns a 404 page:

$ kubectl apply -f default-backend.yaml
deployment "default-http-backend" created
service "default-http-backend" created

$ kubectl -n kube-system get po
NAME                                    READY     STATUS    RESTARTS   AGE
default-http-backend-2657704409-qgwdd   1/1       Running   0          28s

$ kubectl create -f nginx-load-balancer-conf.yaml

Controller

You can deploy the controller as follows:

$ kubectl apply -f nginx-ingress-controller.yaml
deployment "nginx-ingress-controller" created

$ kubectl -n kube-system get po
NAME                                       READY     STATUS    RESTARTS   AGE
default-http-backend-2657704409-qgwdd      1/1       Running   0          2m
nginx-ingress-controller-873061567-4n3k2   1/1       Running   0          42s

Test

Check the contents of the annotation is present in the nginx.conf file using: kubectl exec nginx-ingress-controller-873061567-4n3k2 -n kube-system cat /etc/nginx/nginx.conf
