What is Kubernetes ?
Kubernetes Architecture ?
Deploying a Spring Boot Application in Kubernetes ?

Kubernetes (K8s) is an open-source system for automating deployment, scaling, and management of containerized applications.

Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

The name Kubernetes originates from Greek, meaning helmsman or pilot. Google open-sourced the Kubernetes project in 2014. Kubernetes builds upon a decade and a half of experience that Google has with running production workloads at scale, combined with best-of-breed ideas and practices from the community.

Containers have become popular because they provide extra benefits, such as:

Agile application creation and deployment: increased ease and efficiency of container image creation compared to VM image use.
Continuous development, integration, and deployment: provides for reliable and frequent container image build and deployment with quick and easy rollbacks (due to image immutability).
Dev and Ops separation of concerns: create application container images at build/release time rather than deployment time, thereby decoupling applications from infrastructure.
Observability not only surfaces OS-level information and metrics, but also application health and other signals.
Environmental consistency across development, testing, and production: Runs the same on a laptop as it does in the cloud.
Cloud and OS distribution portability: Runs on Ubuntu, RHEL, CoreOS, on-prem, Google Kubernetes Engine, and anywhere else.
Application-centric management: Raises the level of abstraction from running an OS on virtual hardware to running an application on an OS using logical resources.
Loosely coupled, distributed, elastic, liberated micro-services: applications are broken into smaller, independent pieces and can be deployed and managed dynamically – not a monolithic stack running on one big single-purpose machine.
Resource isolation: predictable application performance.
Resource utilization: high efficiency and density.

Why you need Kubernetes and what can it do
Containers are a good way to bundle and run your applications. In a production environment, you need to manage the containers that run the applications and ensure that there is no downtime. For example, if a container goes down, another container needs to start. Wouldn’t it be easier if this behavior was handled by a system?

That’s how Kubernetes comes to the rescue! Kubernetes provides you with a framework to run distributed systems resiliently. It takes care of scaling and failover for your application, provides deployment patterns, and more. For example, Kubernetes can easily manage a canary deployment for your system.

Kubernetes provides you with:

Service discovery and load balancing
Kubernetes can expose a container using the DNS name or using their own IP address. If traffic to a container is high, Kubernetes is able to load balance and distribute the network traffic so that the deployment is stable.
Storage orchestration
Kubernetes allows you to automatically mount a storage system of your choice, such as local storages, public cloud providers, and more.
Automated rollouts and rollbacks
You can describe the desired state for your deployed containers using Kubernetes, and it can change the actual state to the desired state at a controlled rate. For example, you can automate Kubernetes to create new containers for your deployment, remove existing containers and adopt all their resources to the new container.
Automatic bin packing
You provide Kubernetes with a cluster of nodes that it can use to run containerized tasks. You tell Kubernetes how much CPU and memory (RAM) each container needs. Kubernetes can fit containers onto your nodes to make the best use of your resources.
Self-healing
Kubernetes restarts containers that fail, replaces containers, kills containers that don’t respond to your user-defined health check, and doesn’t advertise them to clients until they are ready to serve.
Secret and configuration management
Kubernetes lets you store and manage sensitive information, such as passwords, OAuth tokens, and SSH keys. You can deploy and update secrets and application configuration without rebuilding your container images, and without exposing secrets in your stack configuration.

When you deploy Kubernetes, you get a cluster.

A cluster is a set of machines, called nodes, that run containerized applications managed by Kubernetes.

Thank You very much for your efforts Sir Could you please create a content for Jenkins Flow along with Kubernetes which can be more helpful to relate the real time Environment.

[rpvijay]

very good, simple, and efficient explanation. I followed so many videos I was not able to understand exactly what is Kubernetes and how it works. Now you made it so clear. Thank you so much, brother.

[vinothjohnson]

Nice explanation..Really helpful..Thanks bro..!!

[sencms]

Appreciated all your efforts, Keep up the good work

Communication between pods on node 1 to pods on node 2 is not explained properly

Can you explain once again?

[vimalprasath]

Thanks for all Kubernetes Videos, Can you pl explain pods restart count

[rajeshdheenan]

Hi Vinoth,
Can you please explain about Pause and Init contaier. How it work in POD.
THanks,
Rajesh. D

unga voice romba slow ah kekuthu, please try to increase the same

[vigneshelan]

good explanation konjam loud ah pesunga romba low ah iruku voice

[tamilselvan]

My humble request pls increase your voice

[rajeshdheenan]

Could you please explain how IP address assign to POD?

[mrramkumar]

Good explained bro, need more videos like DevOps related!!!
