In my DevOps Journey Week 14, I moved from Docker & Compose into the world of Kubernetes.
This was a huge milestone: learning how to handle scaling, automation, and thousands of users without downtime.
๐น Step 1: Docker Networking
Before K8s, I explored Docker networking:
- Bridge โ local isolated communication
- Host โ container shares hostโs network
- Overlay โ multi-host (Swarm, cluster setups)
๐น Step 2: Docker Compose
Next, I practiced multi-service apps:
yaml
version: "3.9"
services:
web:
image: nginx
db:
image: mysql:5.7
With a single command:
bash
Copy code
docker-compose up -d
This was enough for small dev projects.
๐น Step 3: Kubernetes โ the Game Changer
Hereโs where Week 14 really leveled up.
Kubernetes gave me:
Scaling โ add more pods instantly.
Self-healing โ crashed pods restart automatically.
Rolling updates โ zero downtime deploys.
Load balancing โ spread traffic across pods.
Commands I used:
bash
Copy code
kubectl create deployment web --image=nginx
kubectl expose deployment web --type=NodePort --port=80
kubectl scale deployment web --replicas=5
kubectl get pods
๐ฅ Reflection
Docker was my foundation.
Docker Compose gave me small multi-service apps.
But Kubernetes unlocked production-level orchestration.
This week felt like moving from โdeveloperโ โ โDevOps engineer.โ
