What is Kubernetes? How do you use it?

Kubernetes is a container orchestration system that automates deployment, scaling, and management of containerized applications. It allows running applications as pods, managing their state, load balancing, and ensuring fault tolerance.

In my work, I use Kubernetes to automate test environments, where I run services and databases in containers. This enables quick creation of isolated testing environments, easy scaling of load, and management of configurations through YAML manifests. Kubernetes also helps integrate tests into CI/CD pipelines, ensuring stability and repeatability of test runs.
