How does Kubernetes work?
Kubernetes is an open-source platform designed to automate deploying, scaling, and managing containerized applications. It orchestrates a cluster of virtual or physical machines, grouping applications into containers for efficient resource management.
Key Components
- Master Node: This controls the Kubernetes cluster and is responsible for managing the state of the cluster, scheduling applications, and scaling.
- Worker Nodes: These run the applications and contain the necessary services to execute and manage containers.
- Pods: The smallest deployable units in Kubernetes, which encapsulate one or more containers, storage, and networking settings.
- Services: Abstracts access to a set of Pods, allowing for load balancing and stable endpoint communication.
Workflow Process
Kubernetes uses a declarative configuration model. Users define the desired state in YAML files, specifying how applications should run. The Kubernetes control plane then works to ensure the current state matches the desired state by automatically managing container deployments, scaling, and health monitoring.
Benefits
With Kubernetes, developers enjoy automated deployments, scalability, and efficient management of resources, enhancing productivity and streamlining software development practices.
