Kubernetes is a container management technology hosted by google to manage respectable applications in different fields such as physical, virtual, cloud infrastructure.it is an open-source system i.e everyone can access easily.

Kubernetes comes with the ability to automate implementation, ascending of applications and operations of application containers across the clusters.it capable of creating a container-centric infrastructure.

Kubernetes architecture:

Kubernetes follows the client-server architecture. The architecture of Kubernetes follows the 2 machines one is a master machine and the other one is the node on the separate Linux machines.

Kubernetes-Master Machine Components:

Given below are the components of the Kubernetes course -Master Machine.


It stores the configuration information which can be used by each node in the cluster. It has a high availability key-value store that can be distributed among multiple nodes. It is accessible only by the Kubernetes API server as it may have some sensitive information. It has distributed key-value stores that are accessible to everyone.

API Server:

Kubernetes API server provides all the operations in the cluster using API. API server provides an interface, i.e different tools and libraries can instantly communicate with it.

Controller manager:

This component is responsible for most of the representatives that regulate the state of a cluster and performs a task. It is run on the continuation loop and is responsible for sending and collecting information to API Server.

It works toward the shared state of the cluster then makes a change to the current state of the server to the desired state. The key controllers of these components are the replication controller, namespace controller, endpoint controller, service account controller.


A scheduler is one of the key components of the Kubernetes Training master. It is a service in master responsible for allocating the workload. It is responsible for the upcoming utilization of workloads on cluster nodes then placing the workload on which resources available and accept the workload.

Kubernetes-Node components:

The following are the key components of Kubernetes-Node components which mostly communicate with Kubernetes master.


Docker is the initial requirement in the node component. Docker helps in running the encapsulated application containers is a relatively isolated but lightweight operating environment.

Kubelet service:

This is a small service in which each node responsible for transforming information to and from control panel service. It communicates with etcd store to read configuration details and write values. This communicates with the master component to receive commands and works.

Kubernetes proxy server:

This is a proxy service that can run and execute on each node and helps in services available to external users. It helps in forwarding the request to correct containers and capable of performing primitive load balance.

Uses of Kubernetes:

Kubernetes is one of the open-source container symmetry tools for enterprises. It provides application implementation, ascending, container management, other capabilities.

To solve the following problems we use Kubernetes:


vendor-challenger provides the operators to design, build, and manage multi-cloud and hybrid cloud platforms very easily and safely with the risk of vendor-lockin platforms. Kubernetes also eliminates the problems of the multi or hybrid cloud strategy.


To develop microservices applications, Java developers must control service availability and can easily respond to clients. Kubernetes provides this feature because developers don’t have to manage anything on their own.


Kubernetes Invocation feature provides bug fixes, function enhancements, security. Mostly, it enables advanced deployment strategy.


Elasticity is the key capability needed to handle a huge amount of work in a cloud environment. If we want to build a container platform we can improve the system reliability or end-users.


To deploy resilience problems we use Kubernetes. In a modern application architecture, failure handling codes should be considered to control unexpected errors and recover from them quickly. But it takes a lot of time and effort for developers to simulate all the occasional errors.

Features of Kubernetes:

The following are some of the important features of Kubernetes.

  • Continuous development and integration development.
  • Containerized framework.
  • Automatic scheduling.
  • Application-centric management.
  • expandable framework.
  • It provides a high density of resource utilization.
  • The substance of resource utilization.

Advantages of Kubernetes:

  • Documentation provides every bit of information.
  • It provides simple and fast configuration access to your business.
  • It has a simple configuration can easily interact with docker.

I hope this topic can give some awareness of Kubernetes. Get more info at Kubernetes online training
