Deploying a Scalable Web App on gcloud via YAML Configurations

Due to its simplicity and readability, YAML is the preferred standard for writing configurations for Kubernetes by DevOps developers and system administrators. It’s a de facto standard for writing configurations for Kubernetes. It consists of key-value pairs organized as a list where the hierarchy is established using indentation.

This project will deploy a simple Django application on the Google Cloud Platform through gcloud, Kubernetes CLI, and YAML configurations. The project incorporates a range of tasks to facilitate the deployment and maintenance of applications, ensuring seamless and high-performing experiences for end users, and also shows how to add powerful capabilities like zero-downtime deployments, rolling updates, and rollback procedures through YAML configuration files. It establishes a robust version tracking system to monitor changes, updates, and modifications to applications. It also integrates horizontal pod autoscaling (HPA) via YAML, automatically adjusting resources based on application demand. Additionally, services are exposed using NodePort and load balancer in the YAML configuration to ensure that applications remain accessible to users, even as they scale and evolve. The project also incorporates YAML-based ReplicaSets and automatic repair mechanisms to maintain application reliability.
