# Kubernetes Engine: Qwik Start

LAB 5

## Overview

[Google Kubernetes Engine](https://cloud.google.com/kubernetes-engine/) (GKE) provides a managed environment for deploying, managing, and scaling your containerized applications using Google infrastructure. The Kubernetes Engine environment consists of multiple machines (specifically [Compute Engine](https://cloud.google.com/compute) instances) grouped to form a [container cluster](https://cloud.google.com/kubernetes-engine/docs/concepts/cluster-architecture). In this lab, you get hands-on practice with container creation and application deployment with GKE.

## Lab

### Set a default compute zone <a href="#step4" id="step4"></a>

Select [your zone](https://cloud.google.com/compute/docs/regions-zones/#available) wisely! Enter the following command to set your zone!

```
gcloud config set compute/zone asia-southeast1-a
```

### Creating a GKE Cluster

A [cluster](https://cloud.google.com/kubernetes-engine/docs/concepts/cluster-architecture) consists of at least one **cluster master** machine and multiple worker machines called **nodes**. Nodes are [Compute Engine virtual machine (VM) instances](https://cloud.google.com/compute/docs/instances/) that run the Kubernetes processes necessary to make them part of the cluster.

Enter the following command to create a cluster.

```
gcloud container clusters create neeishere
```

### Get authentication credentials for the cluster <a href="#step6" id="step6"></a>

```
gcloud container clusters get-credentials [CLUSTER-NAME]
```

### Deploy an application to the cluster <a href="#step7" id="step7"></a>

Deploying a test application as shown below.

```
kubectl create deployment hello-server --image=gcr.io/google-samples/hello-app:1.0
```

Creating a Kubernetes Service which lets us expose our application to external traffic:

```
kubectl expose deployment hello-server --type=LoadBalancer --port 8080
```

* `--port` specifies the port that the container exposes.
* `type="LoadBalancer"` creates a Compute Engine load balancer for your container.

Inspect Service as shown below to get the public IP:

```
kubectl get service
```

### Deleting the cluster <a href="#step8" id="step8"></a>

```
gcloud container clusters delete neeishere
```
