Introduction:
Welcome back to Day 42 of the #90DaysDevOpsChallenge! After diving deep into Kubernetes architecture in our last task, it's time to get hands-on with Minikube. Today, we'll explore Minikube, its features, and dive into creating our first Pods.
Minikube: A Quick Overview
What is Minikube? Minikube is a powerful tool designed to swiftly set up a local Kubernetes cluster on macOS, Linux, and Windows. Whether deployed as a VM, a container, or on bare-metal, Minikube delivers the full capabilities of Kubernetes with minimal setup fuss.
Key Features of Minikube:
Latest Kubernetes Support: Stay current with the latest Kubernetes release and enjoy compatibility with six previous minor versions.
Cross-Platform: Seamlessly operates on Linux, macOS, and Windows, ensuring flexibility across different environments.
Versatile Deployment: Choose your deployment method - VM, container, or bare-metal - to suit your specific needs.
Container Runtimes: Supports multiple container runtimes including CRI-O, containerd, and docker, providing runtime flexibility.
Direct API Endpoint: Experience lightning-fast image loading and building with a direct API endpoint, boosting development efficiency.
Advanced Features: Benefit from advanced features like LoadBalancer, filesystem mounts, FeatureGates, and network policy, enhancing functionality.
Addon Support: Easily install Kubernetes applications with addons, simplifying management of additional features.
CI Environment Support: Seamlessly integrate with common CI environments, ensuring smooth operations across your development pipeline.
Task-01: Installing Minikube Exciting news - I've successfully installed Minikube on my local machine! Following the step-by-step instructions provided on the official Minikube installation page made the process a breeze.

Understanding Pods
What are Pods? Pods are the smallest deployable units of computing in Kubernetes. They represent one or more containers sharing storage and network resources, each specified with its configuration. Think of a Pod as a cohesive unit that encapsulates your application's functionality.
Practical Implementation: Task-02 Time to put theory into action! I've created my first Pod on Kubernetes using Minikube. For this demonstration, I opted to deploy an Nginx Pod, showcasing Minikube's versatility.
Here's a simple YAML configuration for an Nginx Pod:
Saving this YAML configuration in a file (e.g., pod.yaml) and applying it creates the Pod:
kubectl apply -f nginx-pod.yaml
And just like that, we've embarked on our Kubernetes journey with Minikube! Stay tuned for more thrilling adventures on our DevOps expedition. 🚀✨
