DevOps

DevOps has become a word that covers too much. For a small team it means three things in practice: that the development environment resembles production, that deploying does not depend on one specific person, and that you can roll back quickly when something breaks. This selection sticks to that. There are Kubernetes courses in the catalogue, but we deliberately did not put them first: most teams that hire us do not need it yet, and adopting it too early adds more problems than it solves.

Who it is for

• Developers who deploy by hand and know it does not scale.
• Teams where only one person knows how code reaches production.
• Anyone who wants to understand containers without jumping straight to orchestration.

What you will learn

• Docker properly: reproducible images, layers and why yours weighs a gigabyte.
• Continuous integration and deployment with pipelines that fail early and clearly.
• Deployment and rollback strategies without downtime.
• Observability: logs, metrics and alerts someone actually reads.

Recommended order

1. Docker first, until you can containerise your own project without copying a Dockerfile.
2. CI/CD next, automating the tests you already have.
3. Kubernetes only if your scale justifies it. Not before.
