Introduction

This repository provides a step-by-step guide to setting up a Kubernetes environment with GKE Autopilot and using Google Cloud Shell for management and deployment tasks.

Prerequisites

Before you begin, make sure you have the following prerequisites:

• A Google Cloud Platform (GCP) account with billing enabled.
• Google Cloud SDK (gcloud) installed on your local machine.
• Access to a GKE cluster with Autopilot enabled.

Google Cloud Shell

Google Cloud Shell provides a browser-based shell environment that you can use for managing your GCP resources and interacting with Kubernetes clusters.

To access Google Cloud Shell, follow these steps:

Log in to your GCP Console. Click on the "Activate Cloud Shell" button in the upper-right corner.

Install HELM

To install HELM, use the following commands:

Add & Update the HELM repository

helm repo add helm https://helm.sh/helm

helm repo update

Install nginx-controller

To install the nginx-controller, use the following commands:

Add & Update the nginx-controller repository

helm repo add nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install nginx nginx/ingress-nginx 
helm search repo nginx

List all ValidatingWebhookConfigurations in all namespaces

kubectl get ValidatingWebhookConfiguration -A

Delete a ValidatingWebhookConfiguration (e.g., nginx-ingress-nginx-admission)

kubectl delete -A ValidatingWebhookConfiguration nginx-ingress-nginx-admission

On Shell

Create a Namespace

You can create a Kubernetes namespace using the following command:

kubectl create namespace <namespace-name>

Deploy an Application using Kustomize

To deploy an application, apply the YAML configuration file to your namespace:

kubectl apply -k <path-to-overlays-environment> 

Useful Commands

Here are some useful commands to help you manage your Kubernetes environment:

# List all pods in the current namespace
kubectl get pods -n <>namespace>

# Create a new Kubernetes namespace (e.g., "dev" or "sit")
kubectl create ns <namespace-name>

# Apply a YAML configuration file to create resources
kubectl apply -f <path-to-yaml-file>
