🚀 Let's Get Started with Pods! 🐝

Welcome to this quick guide on deploying your first Kubernetes pod using Minikube. We'll walk through setting up your environment, creating a pod configuration, deploying it, and verifying everything works smoothly. Ready to dive in? Let’s go! ⚙️🐳

1. Environment Setup ⚙️

First, we started our Minikube cluster (Make sure you've set up Docker Desktop 🐳 on the machine before this tutorial, and it's running):

minikube start --driver=docker --cpus=2 --memory=4096mb
(recommended to run this amount of resources)

# Check kubectl context 🔍

kubectl config current-context

# Check cluster info 📋

kubectl cluster-info

2. Pod Configuration 🐝

I used the following YAML configuration:

apiVersion: v1
kind: Pod
metadata:
  name: nginx-pod
  labels:
    app: web
    tier: frontend
spec:
  containers:
  - name: nginx
    image: nginx:1.14
    ports:
    - containerPort: 80
    resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"

Save YAML file as "01-simple-pod.yaml" in the 'exercises/1-basics/pods folder'.

3. Pod Deployment and Verification 🚀

# Deploy the pod 🧩

kubectl apply -f exercises/1-basics/pods/01-simple-pod.yaml

# Verify pod status ✅

kubectl get pods

# Get detailed pod information 📝

kubectl describe pod nginx-pod

# View pod logs 📜

kubectl logs nginx-pod

# Set up port forwarding 🔌

kubectl port-forward nginx-pod 8080:80

4. Understanding the Components 🧩

• Pod Configuration:
  • apiVersion: v1 - Specifies Kubernetes API version 🛠️
  • kind: Pod - Defines resource type 📦
  • metadata - Contains pod name and labels 🏷️
  • spec - Defines pod behavior and containers ⚙️
• Resource Limits:
  • Requests (minimum): 250m CPU, 64Mi memory ⚡
  • Limits (maximum): 500m CPU, 128Mi memory 🚧
• Networking:
  • Container Port: 80 (nginx default) 🌐
  • Port Forward: localhost:8080 → pod:80 🔄

5. Current Status 📊

The pod is running with:

• Name: nginx-pod 🐱‍👤
• Status: Running 🟢
• Accessible via: http://localhost:8080 🌍

Common Commands Reference 📚

# Get pod status 🔎

kubectl get pods

# Get detailed pod info 📝

kubectl describe pod nginx-pod

# Delete pod 🗑️

kubectl delete pod nginx-pod

# Get pod logs 📜

kubectl logs nginx-pod

# Execute command in pod 🖥️

kubectl exec -it nginx-pod -- /bin/bash

Have a look, explore the pod and what's in there. Using Linux commands ls (to view the current directory contents) and cd (to traverse the directories) 🐧.

To STOP 🛑

Great job! You’ve successfully deployed and explored your first pod. Remember to stop and clean up your Minikube cluster to free resources when you’re done:

# Stop minikube 🛑

minikube stop

# Delete minikube cluster 🧹

minikube delete

You're now ready to move onto the next tutorial! Happy Kubernetes-ing! 🐳✨
