## Google Cloud compute options for Kubernetes -> Getting started with GKE

## Prerequisites: Ensure that the GKE and Cloud operations API are enabled in your GCP project.

Start by setting the project id PROJECT_ID=”<your-project-id>"

Enable the GKE API & Enable the Cloud operations API

 gcloud services enable apigateway.googleapis.com
 gcloud services enable servicemanagement.googleapis.com
 gcloud services enable servicecontrol.googleapis.com

Start by setting the project ID using the below command:
```
 gcloud config set project <<project id>
```
Set the compute zone for the cluster. For this demo, we will be using the zone us-central1-a
```
 gcloud config set compute/zone us-central1-a
```
Let’s now create a GKE standard cluster named ‘testcluster’, with default settings and single node in the node pool with auto scaling enabled
```
 gcloud container clusters create hello-cluster — enable-autoscaling — min-nodes=1 — max-nodes=3
```

Clone the Microservices demo application

 git clone https://github.com/574n13y/microservices-demo.git
 cd microservices-demo

Deploy the sample application to the GKE cluster

 kubectl apply -f ./release/kubernetes-manifests.yaml

Once the deployment is completed successfully, you should be able to see the namespace
```
 kubectl get ns
```
Once the deployment is completed successfully, you should be able to see the pods associated with the application using the following command
```
 kubectl get pods
```
Access the application using its external IP address at Port 80
```
 kubectl get service frontend-external | awk '{print $4}'
```
Alternatively, you can also browse to Kubernetes Engine service in GCP portal -> services and ingress and look for the endpoint of the service named “frontend-external”.

The application will open once you click on the link:
