Basic Pod Commands

# 🐳 Basic Pod Commands

This section covers essential commands and YAML for working with Pods — the smallest unit in Kubernetes.

---

## ✅ Create a Simple Pod

```bash
kubectl run nginx-pod --image=nginx

---

🛠️ Generate Pod YAML (Dry Run)

kubectl run nginx --image=nginx --dry-run=client -o yaml

This is useful for producing a manifest file you can tweak before applying.

---

🔍 Inspect a Pod's Image

kubectl get pod <pod-name> -o jsonpath="{.spec.containers[*].image}"

---

🗑️ Delete a Pod

kubectl delete pod <pod-name>

Example:

kubectl delete pod webapp

---

📄 Create a Pod from YAML

You can define a Pod manually in a YAML file, even with a broken image (useful for testing failure states):

apiVersion: v1
kind: Pod
metadata:
  name: redis
spec:
  containers:
  - name: redis
    image: redis123  # incorrect image for demo/testing

Save this to redis-pod.yaml and apply it:

kubectl apply -f redis-pod.yaml

---

✅ Summary

• Pods are ephemeral units running your containers
• Use kubectl run for quick tests, or YAML for reusable configurations
• Always validate with kubectl describe and kubectl logs if things go wrong
