Hey everyone 👋
Today was one of those days in my Kubernetes journey where things started to feel a bit complex and overwhelming, but I chose not to give up. Instead, I chose to document, reflect, and move ahead — one step at a time.
🌸 Radhe Radhe for the strength, and let's begin.

🧠 What I Learned Today

This session focused on two crucial building blocks of Kubernetes:

Pods – the smallest deployable unit in K8s
YAML – the configuration language we use to define everything in Kubernetes

📌 Key Takeaways

🐳 Pods – The Core of Kubernetes

A Pod is the smallest unit you can deploy in K8s. It usually wraps a single container but can hold more than one if needed.

Example (Imperative):

kubectl run nginx --image=nginx

📄 YAML – Your Way to Talk to Kubernetes

Kubernetes loves YAML. Here's why it matters:

Human-readable
Spacing-sensitive (no tabs!)
Used to define every resource in a cluster

A basic pod YAML looks like this:

apiVersion: v1 kind: Pod metadata: name: mypod spec: containers: - name: nginx-container image: nginx

🧩 Imperative vs Declarative

🧪 Imperative (`kubectl run`)	📂 Declarative (`kubectl apply -f`)

Great for quick testing

Best for production setup

Not version controlled

Can be stored in Git

Less flexible

Full control and history

kubectl run nginx --image=nginx --dry-run=client -o yaml > pod.yaml

🔍 Troubleshooting & Useful Commands

kubectl describe pod – See events and logs for debugging
kubectl get pods -o wide – See node info
kubectl get pods --show-labels – Filter with labels
kubectl exec -it pod-name -- bash – Get inside a running Pod
kubectl edit pod pod-name – Edit directly in terminal (using vi)

💬 My Reflections

Today wasn’t easy.

There were moments when:

The concepts felt abstract
Tools like KIND were heavy to download
Hands-on felt out of sync with the theory

But instead of switching tracks or getting frustrated, I reminded myself:

“Learning something powerful will never feel easy — that’s what makes it powerful.”

And with discipline and a bit of faith in Shree Krishna & Radha Rani, I kept going.
