📌 What about doing some hands-on now?

Let's read about minikube and implement k8s in our local machine

1. What is minikube?

Ans:- Minikube is a tool that quickly sets up a local Kubernetes cluster on macOS, Linux, and Windows. It can deploy as a VM, a container, or on bare-metal.

Minikube is a pared-down version of Kubernetes that gives you all the benefits of Kubernetes with a lot less effort.

This makes it an interesting option for users who are new to containers, and also for projects in the world of edge computing and the Internet of Things.

Features of minikube

Ans:-

(a) Supports the latest Kubernetes release (+6 previous minor versions)

(b) Cross-platform (Linux, macOS, Windows)

(c) Deploy as a VM, a container, or on bare-metal

(d) Multiple container runtimes (CRI-O, containerd, docker)

(e) Direct API endpoint for blazing-fast image load and build

(f) Advanced features such as LoadBalancer, filesystem mounts, FeatureGates, and network policy

(g) Addons for easily installed Kubernetes applications

(h) Supports common CI environments

📌 Task 01: Install minikube on your local

Step 1: Install and enable docker

sudo apt update
sudo apt install -y curl wget apt-transport-https
sudo apt install -y docker.io
sudo systemctl enable --now docker
sudo usermod -aG docker $USER && newgrp docker

Step 2: Install Minikube

curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
chmod +x minikube
sudo mv minikube /usr/local/bin/

Step 3: Install Kubectl

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x kubectl
sudo mv kubectl /usr/local/bin/

Step 4: Start Minikube and check the status

minikube start --driver=docker
minikube status

📌 Let's understand the concept of pod

Ans:-

Pods are the smallest deployable units of computing that you can create and manage in Kubernetes.

A Pod (as in a pod of whales or pea pod) is a group of one or more containers, with shared storage and network resources, and a specification for how to run the containers. A Pod's contents are always co-located and co-scheduled, and run in a shared context. A Pod models an application-specific "logical host": it contains one or more application containers that are relatively tightly coupled.

📌 Task 02: Create your first pod on Kubernetes through Minikube.

Create the pod. yaml file

Create the pod using the command - kubectl apply -f pod. yaml

Check the pod with the command - kubectl get pods
