This is my first post about K8s, as a Senior Frontend Engineer, I started expanding my learning and knowledge in cloud-native applications and deployments. So, sharing my learning here.

In the ever-evolving landscape of cloud-native applications, Kubernetes has emerged as a powerful platform, orchestrating container-based applications with unparalleled efficiency and scalability. This article delves into the key aspects of Kubernetes, from its foundational principles to its practical usage and troubleshooting techniques.

Understanding Kubernetes

At its core, Kubernetes is a platform designed for running container-based cloud-native applications. By leveraging containerization technology, Kubernetes offers a way to encapsulate and deploy applications and their dependencies in a consistent and reproducible manner. Stemming from Google’s Borg technology, Kubernetes inherits a robust foundation for managing containers, with a focus on scalability, availability, and efficient orchestration.

Key Features of Kubernetes

  1. Cloud-Native Architecture: Kubernetes enables the deployment and management of applications in the cloud, reducing dependencies on local hosts.
  2. Enterprise-grade Scalability and Availability: The platform provides enterprise features, ensuring applications can scale seamlessly and remain available under varying workloads.
  3. Container Orchestration: Kubernetes orchestrates containers to ensure they deliver the required services within a given environment. This orchestration capability streamlines the deployment and scaling of containerized applications.

Containers: The Building Blocks

Containers play a pivotal role in the Kubernetes ecosystem. They are lightweight, and portable, and encapsulate all the dependencies required to run an application. Running instances of container images are managed by container engines, with Docker and Podman being popular choices for standalone computers. Kubernetes enhances containers with cloud features, managing them within pod resources.
