Deploying a Containerized App in Google GKE

Kubernetes has emerged as the industry standard for deploying containerized applications, with Google Kubernetes Engine (GKE) offering a managed service that includes features such as auto-scaling, high availability, and automatic upgrades. The article provides a detailed walkthrough of deploying a containerized application on GKE, beginning with setting up a CLI environment in Google Cloud Platform (GCP) using Cloud Shell. It covers the steps for creating a Docker container image from a microservice application, uploading it to GCP's Container Registry, and deploying it on a Kubernetes cluster. The guide also explains how to scale the application, monitor its performance using tools like ELK or EFK stacks, and expose it to the internet through Kubernetes' LoadBalancer service. Throughout, it highlights GKE's ease of use and reliability, as Google, the creator of Kubernetes, provides a seamless and efficient cluster management experience.
