Tips for DevOps Career Success

1. Build a Home Lab

Run Kubernetes clusters locally (minikube, kind, k3s). Practice breaks things faster than production ever could.

2. Contribute to Open Source

CNCF projects welcome contributors. Even documentation improvements demonstrate expertise.

3. Automate Everything

If you do something twice, automate it. This mindset is the core of DevOps.

4. Learn to Write

Documentation, runbooks, and post-mortems are essential DevOps artifacts. Clear writing shows clear thinking.

5. Embrace On-Call

Production experience is invaluable. Learn from incidents and improve systems.

Conclusion

The DevOps career path rewards continuous learning and hands-on expertise. Start with Kubernetes and Terraform certifications, then progress to professional-level credentials as you gain experience.
