Can you explain how the Kubernetes container orchestrator functions?

The Kubernetes container orchestrator manages the lifecycle of containerized applications, automating deployment, scaling, and management.

Key functions of Kubernetes as an orchestrator:

• Scheduling: distributes containers (pods) across available cluster nodes considering resources and constraints.
• Auto-scaling: increases or decreases the number of application replicas based on load.
• Availability assurance: restarts failed containers, replaces nodes in case of failures.
• Configuration and secret management: centrally stores and updates application parameters.
• Updates and rollbacks: allows smooth application updates without downtime.

Kubernetes uses controllers and an API server to monitor the desired state of the cluster and automatically bring the current state to it.
