The primary function of Kubernetes is container orchestration and management.

Here's a step-by-step explanation:

1. Container Orchestration: Kubernetes is primarily used to manage, scale, and maintain containerized applications across clusters of nodes. This is known as container orchestration. It ensures that the system knows where to run a container, how many copies to run, and what to do in case a container goes down.

2. Service Discovery and Load Balancing: Kubernetes can expose a container using the DNS name or their own IP address. If traffic to a container is high, Kubernetes is able to load balance and distribute the network traffic to stabilize the deployment.

3. Storage Orchestration: Kubernetes allows you to automatically mount a storage system of your choice, such as local storages, public cloud providers, and more.

4. Automated rollouts and rollbacks: Kubernetes progressively rolls out changes to your application or its configuration, while monitoring application health to ensure it doesn't kill all your instances at the same time. If something goes wrong, Kubernetes will rollback the change for you.

5. Secret and configuration management: Kubernetes lets you store and manage sensitive information, such as passwords, OAuth tokens, and ssh keys. You can deploy and update secrets and application configuration without rebuilding your image and without exposing secrets in your stack configuration.

In summary, Kubernetes provides a platform for automating deployment, scaling, and operations of application containers across clusters of hosts. It works with a range of container tools and runs containers in a cluster, often with images built using Docker.
