Kubernetes is an open-source orchestration system for automating the management, placement, scaling, and routing of containers that has become popular with developers and IT operations teams.

Kubernetes is a container management technology developed in google lab to manage the containerized application in a different kind of environment such as physical, virtual kind of environments such as physical, virtual and cloud infrastructure.

There is an active Kubernetes community and eco-system developing around Kubernetes with thousands of contributors.

Kubernetes is an open-source system which helps in creating and managing the containerization of applications.



·       Who wants to start with Kubernetes should know the basics of docker.

·       How the docker images are created.

·       To learn about advanced configuration, one should understand basic networking and how the communication protocol works.


Kubernetes Architecture

Kubernetes follows client-server architecture wherein the master is installed on one machine and node on separate machines.kubernets has a decentralized architecture that does not handle tasks sequentially. These steps illustrate the basic Kubernetes process.

·       An administrator creates and places the desired state of an application.

·       Kubernetes API server using a CLI or UI. Kubernetes default command-line tool is called kubectl.

·       Kubernetes stores the file in a database called the key-value store (etcd).

·       Kubernetes implements the desired state on all the relevant applications within the cluster.

·       Kubernetes continuously monitors the elements of the cluster to make sure the current state of the application remains same and does not vary from the desired state.



Kubernetes Features

Automated rollouts & rollbacks

·       Service discovery and load balancing

·       Service topology

·       Storage orchestration

·       Secret and configuration management

·       Automatic bin packing

·       Batch execution

·       Self-healing

·       Horizontal Scaling

 Kubernetes Advantages

 Kubernetes has become the standard orchestration platform for containers.Kubernetes provides a common framework to run distributed systems. So development teams have consistent. Kubernetes can manage scaling requirements, availability, failover, deployment patterns, and more.

Advantages of Kubernetes

Kubernetes has many powerful and advanced capabilities.

Availability: Kubernetes clustering has way high fault tolerance built-in, allowing for extremely large scale operations.

Auto Scaling: Kubernetes can scale up and scale down based on traffic and server load automatically.

Extensive Ecosystem: Kubernetes has a strong ecosystem around a container networking interface container storage interface and inbuilt logging and monitoring tools.

Kubernetes applications can run in a hybrid and multi-cloud environment.

Kubernetes provides a set of primitives, collectively known as a federation for keeping multiple clusters in sync with one another across multiple regions & clouds. A given app deployment can be kept consistent between multiple clusters and different clusters.


Where Kubernetes is available in many forms

If you want to do it all yourself: The source-code and pre-built binaries for most common platforms.

If you are using community or docker enterprise: Docker's most recent editions come with Kubernetes as a pack-in. This is the easiest way for container mavens to get a leg up with Kubernetes.


Deploying ASP.Net core application to Kubernetes

This series does not focus on using docker with ASP.NET core in general. Kubernetes is an open-source platform for containers,it manages the life cycle and networking of containers scheduled to run. Kubernetes is unlikely to bring you value.

 Components for developers

·       Nodes

·       Pods

·       Deployments

·       Services

Nodes: Nodes in a Kubernetes clusters are virtual machines or physical hardware.

Pods: To run your applications in Kubernetes. Pod is the smallest unit that you can ask Kubernetes to run.
