Kubernetes (k8s) API is a way to interact with the Kubernetes cluster. It is a RESTful API that allows users to programmatically manage and deploy applications on Kubernetes. The API provides a set of resources, such as pods, services, deployments, and namespaces, that can be accessed and manipulated using HTTP requests.
The k8s API is the backbone of the Kubernetes system, and it is used by all other components, including the CLI tool kubectl, the Kubernetes dashboard, and other third-party tools.
Some common operations that can be performed using the k8s API include:
- Creating, updating, and deleting pods, services, and deployments
- Scaling up or down the number of replicas for a deployment
- Rolling out updates to an application
- Monitoring the status and health of the Kubernetes cluster
The k8s API is extensible and can be customized to meet specific requirements. Users can create their own custom resources and controllers to automate various tasks and integrate Kubernetes with other systems.
Overall, the k8s API provides a powerful mechanism for managing containerized applications at scale, making it a critical component of modern cloud-native architectures.
