Installing Google Cloud SDK on your macOS

Make sure that Python 2.7 is installed on your system:

Ajeets-MacBook-Air:~ ajeetraina$ python -V
Python 2.7.10

Download the corresponding version of Google Cloud SDK. In this case the Mac OS version for 64-bits systems is downloaded.


Untar the downloaded file, as follows:

tar xfz google-cloud-sdk-195.0.0-darwin-x86_64.tar.gz

and execute the following command to install Google Cloud SDK in your system:


Initializing the SDK

gcloud init

In your browser, log in to your Google user account when prompted and click Allow to grant permission to access Google Cloud Platform resources.

Enabling Kubernetes Engine API

Authenticate Your Google Cloud

gcloud auth login

Creating GKE Cluster

gcloud container clusters create k8s-lab1 --disk-size 10 --zone asia-east1-a --machine-type n1-standard-2 --num-nodes 3 --scopes compute-rw

Viewing it on Docker for Mac UI

You should be able to view GKE cluster under Preference UI by now.

Be aware that your Kubernetes context can be named differently and it depends on the project’s name under which the Kubernetes cluster is being deployed.

Listing the Nodes

kubectl get nodes

You can connect to your cluster via command-line or using a dashboard. Remember your project’s name can be different.

gcloud container clusters get-credentials k8s-lab1 --zone asia-east1-a --project captain-199803

Deploy Nginx on GKE Cluster

$ kubectl run nginx --image=nginx --replicas=3

deployment "nginx" created

Verify that the pods are running

kubectl get pods -owide
NAME                    READY     STATUS    RESTARTS   AGE       IP          NODE
nginx-7c87f569d-glczj   1/1       Running   0          8s   gke-k8s-lab1-default-pool-b2aaa29b-w904
nginx-7c87f569d-pll76   1/1       Running   0          8s   gke-k8s-lab1-default-pool-b2aaa29b-2gzh
nginx-7c87f569d-sf8z9   1/1       Running   0          8s   gke-k8s-lab1-default-pool-b2aaa29b-qpc7

You can see that each nginx pod is now running in a different node (virtual machine).

Expose the nginx cluster as an external service

$ kubectl expose deployment nginx --port=80 --target-port=80 \

service "nginx" exposed

Find the network load balancer address:

kubectl get service nginx
NAME      TYPE           CLUSTER-IP    EXTERNAL-IP   PORT(S)        AGE
nginx     LoadBalancer   <pending>     80:30253/TCP   12s

It may take several minutes to see the value of EXTERNAL_IP. If you don’t see it the first time with the above command, retry every minute or so until the value of EXTERNAL_IP is displayed.

You can then visit http://EXTERNAL_IP/ to see the server being served through network load balancing.

GKE provides amazing platform to view Workloads & Load-balancer as shown below:

GKE also provides UI for displaying Loadbalancer:

Cleaning Up

gcloud container clusters delete k8s-lab1 --zone asia-east1-a
