ACCESS TO ALL FREE PREMIUM COURSE:
Full Certified Kubernetes Application Developer (CKAD) Course:
In this video, the author (Mumshad Mannambeth) will walk you through the fundamentals of the Kubernetes API. The different API groups and versions, how as an external user you can get access to the Kubernetes API, API deprecation policy, how different APIs evolved and move through different phases. Also, the API lifecycle and finally we will see a hands-on demo of hands-on labs where we explore the Kubernetes API.
What is Kubernetes?
Kubernetes is an open-source container orchestration system for managing containers on a cluster of hosts. Also, Kubernetes is more than just a “container orchestrator.” It’s also a way to manage all the resources on a server or cluster so that they can be maximally utilized without running out of resources.
Uses of Kubernetes API:
The Kubernetes API is the core of Kubernetes. The API is the remote interface that enables users to create, configure, and delete Kubernetes objects. It allows developers to extend Kubernetes by creating controllers that drive the system. The controllers are responsible for things like replication, scaling, and rollout of new versions.
The Kubernetes API can be used to deploy applications, pull images from the registry, or even monitor cluster state. In addition, it can also be used for performing rolling upgrades and managing network policies.
The API provides programmatic access to all the features in Kubernetes. With it, developers can automate the deployment of applications, manage workloads, or access information about the cluster. In addition, familiarity with the API helps one know how to best use Kubernetes and kubectl commands to manage pods, services, replication controllers, etc., without needlessly typing commands.
