What is Kubernetes cluster used for?
Kubernetes is a cluster and container management tool. It lets you deploy containers to clusters, meaning a network of virtual machines. It works with different containers, not just Docker. The basic idea of Kubernetes is to further abstract machines, storage, and networks away from their physical implementation.
What is kind cluster in Kubernetes?
kind is a tool for running local Kubernetes clusters using Docker container “nodes”. kind was primarily designed for testing Kubernetes itself, but may be used for local development or CI. Go packages implementing cluster creation, image build, etc. A command line interface ( kind ) built on these packages.
What are pods and clusters in Kubernetes?
A cluster is central to the basic architecture of Kubernetes: If you’re running Kubernetes, you’re running at least one cluster. A pod is a unit of replication on a cluster; A cluster can contain many pods, related or unrelated [and] grouped under the tight logical borders called namespaces.”
What is cluster and namespace in Kubernetes?
Namespaces are a way to organize clusters into virtual sub-clusters — they can be helpful when different teams or projects share a Kubernetes cluster. Any number of namespaces are supported within a cluster, each logically separated from others but with the ability to communicate with each other.
What are cluster containers?
Simply put, a container cluster is a dynamic system that places and manages containers, grouped together in pods, running on nodes, along with all the interconnections and communication channels.

What is node and cluster?
Nodes store and process data. Nodes can be a physical computer or a virtual machine (VMs). VMs are software programs in the cloud that allow you to emulate a physical computing environment with its own operating system (OS) and applications. A cluster is a group of servers or nodes.
What are the different parts of a Kubernetes cluster?
A working Kubernetes deployment is called a cluster. You can visualize a Kubernetes cluster as two parts: the control plane and the compute machines, or nodes. Each node is its own Linux® environment, and could be either a physical or virtual machine. Each node runs pods, which are made up of containers.
What is name space in EKS?
Namespaces are a way to divide cluster resources between multiple users (via resource quota). With EKS you can take advantage of using powerful AWS IAM implementation. EKS authentication layers supports both IAM Users and IAM Roles.
