Docker and Kubernetes are essential skills for modern software development and DevOps. If you deploy software to the cloud, you need to know these tools.
Docker vs Kubernetes
- Docker = Packages your app into a container (like a shipping container for code)
- Kubernetes = Manages many containers at scale (the ship that carries the containers)
Learning Order
- Linux basics (1–2 weeks)
- Docker — images, containers, Dockerfiles, Docker Compose (2–3 weeks)
- Kubernetes basics — pods, deployments, services (3–4 weeks)
- Helm charts & advanced K8s (2+ weeks)
Best Docker & Kubernetes Courses
Do I need Docker before Kubernetes?
Yes. Docker teaches containerization fundamentals that Kubernetes builds upon. Learn Docker first, then progress to Kubernetes.
