Kubernetes

What is Kubernetes?

Kubernetes (often shortened to "K8s") is an open-source platform that automates deploying, scaling and managing containerized applications across clusters of machines.

It handles the hard parts of running containers in production — scheduling, self-healing, load balancing and rolling updates — at any scale.

Why employers value it

As companies run more containers, they need orchestration, and Kubernetes is the industry standard. Employers pay well for it because it underpins reliable, scalable cloud-native systems, and the skill is genuinely hard to master.

How to learn it

Be comfortable with Docker first. Then learn the core objects — pods, deployments, services — and practice on a local or managed cluster. Kubernetes rewards hands-on troubleshooting over theory alone.

• Master Docker and containers before starting
• Learn core objects: pods, deployments, services and config
• Practice on a local cluster (minikube/kind) or a managed one (EKS/GKE)
• Study scaling, health checks, secrets and rolling deployments

Careers that use it

Kubernetes is core to DevOps engineers, platform engineers, cloud engineers and site reliability engineers. It is one of the most valuable and well-paid infrastructure skills.

Market outlook

Cloud-native adoption keeps Kubernetes demand high and rising. Combined with a cloud platform and Docker, it is among the strongest infrastructure skill sets you can build.
