Excited to kickstart my journey into Kubernetes (K8s), the engine behind modern cloud-native applications.
Today, I explored:
🔹 History:
Kubernetes was originally developed by Google (based on their internal system Borg) and released as open-source in 2014. It has become the de-facto standard for container orchestration.
🔹 Monolithic vs Microservices:
Monolithic apps are single, tightly-coupled systems, harder to scale and deploy.
Microservices break applications into smaller, independent services—perfect for Kubernetes management, scaling, and CI/CD pipelines.
🔹 kubectl:
The command-line tool to interact with Kubernetes clusters. It allows managing resources, deploying applications, and inspecting cluster state.
🔹 Architecture:
Kubernetes uses a master-worker architecture:
Master components manage the cluster state.
Worker nodes run containerized applications.
This design ensures high availability, scalability, and self-healing.
🔹 Hands-on setup:
Today I set up my first cluster using Kind (Kubernetes IN Docker)—a lightweight, developer-friendly alternative to Minikube for local clusters.
💡 Tip for beginners: Understanding the architecture and orchestration concepts is more important than just running commands. Once you grasp this, everything else becomes easier.
Looking forward to diving deeper into Pods, Deployments, Job, and real Kubernetes projects in the coming days!
