Deploy Simple NGINX application IN GKE of Google Cloud Platform

Deploy Simple NGINX application IN GKE of Google Cloud Platform

Step 1: Set up Google Cloud Platform (GCP) Project

  1. Create a GCP Account: If you don't have a Google Cloud Platform account, sign up for one.

  2. Create a Project: Create a new project in the Google Cloud Console.

  3. Enable Billing: Make sure to enable billing for your project.

  4. Enable the Kubernetes Engine API: In the Google Cloud Console, navigate to the "APIs & Services" -> "Dashboard." Enable the "Kubernetes Engine API."

Step 2: Enable CloudShell

Step 3: Set Up gcloud Configurations

Run the following commands to configure gcloud with your GCP project:

$gcloud auth login
$gcloud config set project ashok-198510

Replace PROJECT_ID with your GCP project ID.

Step 4: Pull Nginx image, Copy your web-app html file to docker and push to Google Container Registry

  1. First pull the nginx image following command.

     $docker pull nginx:latest

Then run the nginx image

$docker run -d -p 80:80 nginx:latest
  1. second download or create any sample index.html page. Here i cloned from my git hub repo in that repo only copy the index.html and ashok.png.

    a. This is repo link

    git clone

  2. Next copy the index.html and ashok.png for deploying my webpage to internet.

     $docker cp index.html <container-id>:/usr/share/nginx/html/

    Now check the docker container web interface.

    you will get web inerface like this

    Then update the image using docker commit command

    docker commit <containerid> explorewithashok/web:version

     $docker commit <container-id> /web:version1

    Tag the image for push this image to Google container registry using following commands.

    Before this you have to enable the container registry api.

     $gcloud services enable
     $docker tag explorewithashok/web:version1

    Now push the image to Google Container Registry

     $docker push

    this error means you should give docker auth permission to gcloud using following command.

    gcloud auth configure-docker

    After above command issue will reslove.

    Afer image pushed into GCR now go to the Container Registry console.

    these are image details like zone, version, iamge name

    In above it clearly shown we can directly deploy our application using deploy option but we are devops engineer best practice is deploy through Gcloud cli.

Step 5: Setup the zone for Cluster Create a GKE Cluster

Run the following command to create a GKE cluster:

$gcloud config set compute/zone us-central1-a
$gcloud container clusters create <CLUSTER_NAME> --num-nodes=3

Replace CLUSTER_NAME with the desired name for your cluster. Eg: gcloud container clusters create ashoksana --num-nodes=3

Step 5: Configure kubectl

Run the following command to configure kubectl to use your GKE cluster:

$gcloud container clusters get-credentials CLUSTER_NAME

Step 6: Deploy a Sample Website

For deploy the sample website in GKE run following comand:

$kubectl create deployment web-app
$kubectl expose deployment web-app --type LoadBalancer --port 80 --target-port 80
# To get pods
$kubectl get pods
# To get service
$Kubectl get services

Now you want to host application in internet copy the external ip and pppaste it in brower of your desktop.

Congratulations! You've successfully created a GKE cluster and deployed a sample website. Keep in mind that this is a basic setup, and in a production environment, you would likely want to use a more complex configuration and consider security best practices.

After completion of your please delete GKE cluster using following command

gcloud container clusters delete <cluster-name>
