Kubernetes Engine: Qwik Start



​Google 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 instances) grouped to form a container cluster. In this lab, you get hands-on practice with container creation and application deployment with GKE.


Set a default compute zone

Select your zone wisely! Enter the following command to set your zone!
gcloud config set compute/zone asia-southeast1-a

Creating a GKE Cluster

A cluster consists of at least one cluster master machine and multiple worker machines called nodes. Nodes are Compute Engine virtual machine (VM) 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

gcloud container clusters get-credentials [CLUSTER-NAME]

Deploy an application to the cluster

Deploying a test application as shown below.
kubectl create deployment hello-server
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

gcloud container clusters delete neeishere
