Kubernetes is a powerful tool. It can help you manage complex applications and provide you with the ability to easily automate tasks involved in managing them. In this course, we will start exploring Kubernetes from a beginner's standpoint. We will discuss what Kubernetes is and what it does, and we will work with some of the basic functionality of Kubernetes hands-on. We will build a simple Kubernetes cluster. We will also deploy a sample microservice application to the cluster in order to explore how Kubernetes can help easily manage such applications.

A Practical Guide to Kubernetes

Let's see, through a sequence diagram, what happened when we created the Ingress resource.

1. The Kubernetes client (`kubectl`) sent a request to the API server requesting the creation of the Ingress resource defined in the `ingress/go-demo-2.yml` file.

2. The ingress controller is watching the API server for new events. It detected that there is a new Ingress resource.
3. The ingress controller configured the load balancer. In this case, it is nginx which was enabled by `minikube addons enable ingress` command. It modified `nginx.conf` with the values of all `go-demo-2-api` endpoints.

Now that one of the applications is accessible through Ingress, we should apply the same principles to the other.
# Creating Second Ingress Resource
Let's first look into the definition and then create our second resource using `devops-toolkit.yml`.

## Looking into the Definition
Let's take a look at the full definition of all the objects behind the `devops-toolkit` application.

In this lesson, we will first go through the sequential breakdown of Ingress resource creation process and then create the second Ingress resource.
