3 Expose app.md

Exposing a simple node app

Enable the ingress addon

In order to expose services outside of the virtual machine you need to enable minikube's ingress addon:

minikube addons enable ingress

Add a DNS name to kubeapp.local

The ingress.yaml exposes the app on a host called kubeapp.local. This means you will need to add an entry in the hosts file of your machine. On OSX you can:

sudo -s
vi /etc/hosts

Navigate to the last line and press Shift-A, which should place it in append more. Press ⏎ and add a new line similar to the following:

192.168.99.100 kubeapp.local

NB: Your IP address might be different, it will be the IP address shown in the address bar of the Kubernetes UI / dashboard.

Create a services

kubectl apply -f service.yaml

Create an ingress

kubectl apply -f ingress.yaml

Test it

You should now be able to ping the health endpoints:

• http://kubeapp.local/alive
• http://kubeapp.local/ready

Accessing any other URL, including / should result in a "Hello world" message.
