What is Kubernetes?
Kubernetes is an open-source container orchestration platform used for running distributed applications and services at scale. Also known as “k8s” or “kube”, Kubernetes helps in automating manual and tedious activities involved in managing, deploying and scaling containerized applications.
Here’s a quick overview of Kubernetes architecture, its components and how they interact with each other. Let’s read this brief Kubernetes architecture explanation to learn and explore more on the different components of Kubernetes and how its components work together.
What is a Kubernetes Cluster?
A set of nodes to run containerized workloads and applications is known as a Kubernetes cluster. It has two parts:
- The Control Plane( Master Node)
- The Compute Machines or Nodes( Worker Nodes)
The Compute Machines or Nodes( Worker Nodes)
A node is a worker machine within a Kubernetes cluster. It can either be a virtual or a physical machine depending on the cluster. Each node present inside a cluster is managed by the control plane. A node contains multiple or single pods.
Wondering what are pods in Kubernetes? A pod is the simplest unit in the Kubernetes architecture that represents a set of running containers.
Every cluster has at least one worker node. The worker node(s) are responsible to host the Pods. The automatic scheduling of these pods is controlled and managed by the Kubernetes control plane.
The Control Plane or Master Node
The Kubernetes Control plane manages the worker nodes and the pods within the Kubernetes cluster. The components of the control plane help in taking decisions about the cluster and in identifying and responding to events happening inside the cluster.
Here's the Kubernetes architecture diagram with all the components tied together.
