Stop memorizing CI/CD commands. Understand the workflow instead.

Most people try to memorize hundreds of DevOps commands.The best DevOps engineers understand how everything connects.

This handwritten cheat sheet covers the complete CI/CD flow:
✅ Git
✅ Jenkins
✅ Docker
✅ Terraform
✅ Kubernetes
✅ AWS

Learn the flow, not just the commands. Save this for your next deployment or DevOps interview, and share it with someone preparing for DevOps.

GOOGLE GEMINI HAS BRUTAL FEATURES THAT ALMOST NO ONE IS USING.

MOST PEOPLE ONLY USE GEMINI FOR BASIC PROMPTS… WHILE GOOGLE HAS QUIETLY LOADED IT WITH TOOLS THAT REPLACE HOURS OF WORK IN SECONDS.

YOU'RE PROBABLY USING LESS THAN 5% OF WHAT GEMINI REALLY DOES.

HERE ARE 10 HIDDEN GEMINI FEATURES THAT FEEL ALMOST UNFAIR ONCE YOU START USING THEM: 👇

Contained Orchestration(Kubernetes/ECS)

If you're aiming for a DevOps role, learn and understand Container Orchestration and how tools like Kubernetes help run, manage, and scale containers in production.👇

Here’s a quick checklist to guide your practice:

Understand the problems orchestration solves:

- Scaling
- Self-healing
- Load balancing
- Rolling updates & rollbacks
- Service discovery
- Resource limits & quotas

Learn Kubernetes core concepts:

- Pods, Deployments, Services (ClusterIP, NodePort, LoadBalancer)
- ReplicaSets, Namespaces, ConfigMaps, and Secrets

Get familiar with Kubernetes architecture:

- 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 𝗣𝗹𝗮𝗻𝗲: API server, etcd, scheduler, controller-manager
- 𝗪𝗼𝗿𝗸𝗲𝗿 𝗡𝗼𝗱𝗲𝘀: kubelet, kube-proxy, container runtime

Also,

- Practice key kubectl commands.
- Deploy a sample app using a Deployment and expose it via a Service
- Use Git to manage your YAML manifests
- Optionally, explore managed Kubernetes services like EKS, AKS, GKE or alternatives like ECS, Fargate

DevOps Project for Beginners: AWS S3 + CloudFront
Project: Host a Static Frontend on AWS

Want to deploy your frontend without servers? This one is for you!

1. Create an S3 bucket
Make sure it’s named to match your domain (if using one). Enable static website hosting.

2. Upload your static site files
Add your HTML/CSS/JS files (React, Vue, plain HTML, your choice).

3. Set proper bucket policy
Allow public read access to files (or restrict via CloudFront later).

4. Enable versioning (optional)
Track changes to your files over time.

5. Create a CloudFront distribution
Point it to your S3 bucket as the origin.

6. Configure cache settings
Control how long assets stay cached in the browser/edge.

7. Set custom error pages
Handle 404s or SPAs (Single Page Apps) gracefully.

8. Add a custom domain (optional)
Use Route 53 or your DNS provider to point your domain to CloudFront.

9. Configure SSL certificate (HTTPS)
Use AWS Certificate Manager to issue a free SSL certificate.

10. Automate future deployments
Use GitHub Actions and AWS CLI to push new builds to S3 automatically.

This project gives you a real-world feel of cloud-native frontend hosting with zero servers, global CDN, and fast load times. Perfect starter for DevOps and frontend engineers!

Sargodha, Kirana Hills, Nuclear Weapons and Missile Strike

- Why the US intervened?

- There is ONLY one possible scenario running in my head.

- Pakistanis being Pakistanis, they made a dog and pony show of moving their nuclear assets.

- It could be movement of missile TELs or nuclear weapons form known storage sites.

- Now we know we hit Kirana Hills next to Sargodha.

- Kirana Hills is the motherload of weapons, ammunition and of course, nuclear arsenal.

- Just look at the area -
- It houses a Central Ordnance Depot, Central Ammunition Depot and Pakistan's nuclear stockpile within those hills.

- Which should not be surprising if you consider the following facts -

(1) Kushab Nuclear Plant is ~50km from Kirana Hills as the crow flies. It is part of Pakistan nuclear weapons making infrastructure.

(2) Sargodha Air Base - Home to Pakistan's aerial nuclear delivery platform ->F-16s! Hardly 10km from Kirana Hills in a straight line.

See the map below - The tip of the triangle rests on Kushab Nuclear Plant.

- So, my guess on the sequence of events is something like this -

(1) Pakistanis moved nuclear weapons at a time or in a manner where they knew it would be picked-up by the Americans.

(2) It is very much likely that India also picked-up these events in parallel.

(3) And fired a missile right into their nuclear weapons mothership - No, not to destroy the weapons or make them explode but to tell the Pakistanis that 'We See You' and we're ready to call your nuclear bluff.

(4) But the Americans panicked and well, rest is history.

PS: To see details of where exactly strike hit and details of the area, please see excellent work by @JaidevJamwal on his TL.
